Insect pests are mainly tigers, Scarab and so on.1.根腐病1. rotten diseases一般在6月份发生,病原菌为镰刀菌。病菌从根部侵入,使根部腐烂脱皮,木质部呈黑褐色,叶片逐渐萎蔫、干枯。排水不良、苗木过密的阴湿圃地发生率较高。其防治方法是:①及时拔掉病株烧毁;②发病期用70%托布津1000倍液喷雾;③及时排除积水,搞好间苗。Usually occurs in June, the pathogen is Fusarium. The pathogen invades from the root and causes the root to rot and peel, the xylem to be dark brown, and the leaves to wither and wither gradually. There was a high incidence of wet drainage in poor drainage and overdense seedlings. The prevention and cure methods are as follows: 1. Pulling out the diseased plant and burning it in time; 2. Spraying it with 70% tobrazine 1000 times liquid at the onset stage; 3. eliminating the accumulated water in time and improving the seedlings.2.茎腐病2. stem rot有两种情况:①幼苗出土后苗木木质化程度低,病菌易侵入苗茎,尤其在无遮阴措施,不能及时浇水降低地表温度的情况下,更易感染。病菌侵入苗茎后,产生褐色斑点,病斑逐渐扩大,引起茎部腐烂,呈猝倒状。一般发生在6月上旬。其防治方法一是及时浇水;二是连喷3次800倍多菌灵进行防治。②7月份左右,连续降雨和持续高温,使苗木茎部灼伤,苗木茎部变褐色,内皮层组织腐烂,逐渐扩展致根部,叶片逐渐死亡下垂。低洼易积水的苗圃地较易发生。其防治方法一是高温天气要搭阴棚在苗木行间覆草降低土壤温度,有条件的及时灌溉。阴雨天要注意排水,二是发病期间喷1%硫酸亚铁溶液,控制蔓延,三是防止人为碰伤苗木。There are two situations: 1. The lignification degree of seedlings is low after they are unearthed, and the pathogens are easy to invade the stems of seedlings, especially in the absence of shading measures and timely watering to reduce the surface temperature. After the pathogen invaded the stem of the seedling, it produced brown spots, which gradually expanded and caused the stem to rot, showing sudden collapse. It usually occurs in early June. One of its prevention and treatment methods is timely watering; the two is spraying 3 times 800 times carbendazim for prevention and treatment. (2) Around July, continuous rainfall and persistent high temperature caused burns to the stem, browning of the stem, decay of the endothelial tissue, gradual expansion to the root, leaf death and droop. Low lying and easy to accumulate water nursery is easy to happen. One of the control methods is to put up a shady shed to cover grass between rows of seedlings to reduce soil temperature in high temperature weather and to irrigate in time when conditions are available. We should pay attention to drainage in rainy days, spray 1% ferrous sulfate solution during the onset of disease, control the spread, and prevent artificial injury to seedlings.3.叶枯病3. leaf blight病害初期叶先端变黄,黄色部位逐渐变褐坏死,逐步扩展为整个叶片变为褐色脱落。一般苗木生长过密、通风不良的苗圃地发生较严重。其防治方法是:发病时喷多菌灵800倍液。In the early stage of the disease, the leaf tip became yellow, the yellow part became brown and necrotic, and the whole leaf became brown and shedding. Generally, nursery stock with excessive growth and poorly ventilated seedlings is more serious. The prevention and cure method is: 800 times liquid of carbendazim.4.虫害防治4. pest control①土壤消毒。对钙质土壤每667㎡用过筛的农用硫酸亚铁细粉15㎏或喷洒多菌灵和2.5%的敌百虫粉2.5~3㎏。对非钙质土用过筛的熟石炭粉15~20㎏进行消毒;Soil disinfection. For calcareous soils, 15_of screened agricultural ferrous sulfate powder or 2.5_of Carbendazim and 2.5% of trichlorfon powder were sprayed every 667_. Disinfection of 15~20 KC of sifted carbon powder for non calcareous soil was carried out.②堆青草拌敌敌畏等药液诱杀害虫。2. Stir up grass and grass with dichlorvos and other liquid to kill pests.新闻中心aowl原创2018-09-05 14:33绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/585.htm苗木花卉栽培养殖养护管理技术文章:土壤对花卉生长的作用是什么?卉的栽培大都是土壤栽培,土壤的质地直接影响花卉植物的生长发育。盆 栽 花卉因盆土容量有限,根系活动受到限制,更要求营养物质丰富、物理性质良好的土壤。其中应富含腐殖质.松软.通透性好,能长久保持土..苗木花卉栽培养殖养护管理技术文章:土壤对花卉生长的作用是什么?卉的栽培大都是土壤栽培,土壤的质地直接影响花卉植物的生长发育。盆 栽 花卉因盆土容量有限,根系活动受到限制,更要求营养物质丰富、物理性质良好的土壤。其中应富含腐殖质.松软.通透性好,能长久保持土壤的湿润状态。肥沃、疏松、干后不裂、渗透性和排水性能良好、酸度适当的土壤是最好的土质。What is the effect of soil on the growth of flowers and flowers? The cultivation of the plants is mostly soil cultivation, and the texture of the soil directly affects the growth and development of flower plants. Because of limited capacity of potted soil, the activity of root system is restricted, and the soil with rich nutrients and good physical properties is required. It should be rich in humus. It is soft. It has good permeability and can keep the soil moist for a long time. Fertile, loose, dry, non cracked, well penetrated and well drained soils with good acidity are the best soil.盆 花宜选用什么样的土壤?​栽花卉宜选用有良好的团粒结构、疏松而又肥沃、保水排水性能良好,同时还富含丰富腐殖质的中性或微酸性土壤,但这种土壤性质是任何一种天然土壤都不具备的。因此.盆花 培养土需根据各种花卉植物的不同生长习性、不同生长阶段进行人工合理配制,以满足花卉生长发育的需要。What kind of soil should be selected for potted flowers? Plants should be selected with good pellet structure, loose and fertile, good water conservation and drainage, and also rich in rich humus neutral or micro acid soil, but the nature of this soil is not available in any kind of natural soil. Therefore, the potted flower culture soil should be artificially prepared according to the different growth habits of various flower plants and different growth stages, so as to meet the needs of the growth and development of flowers.苗木,花卉新闻中心aowl原创2018-07-13 17:48绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/584.htm嫩枝扦插是指在苗木的生长季节,采用当年生半成熟的枝条作为插条的扦插方法,它主要适用于常绿和半常绿木本花卉。如茶花、杜鹃、金叶女贞、桂花、罗汉松、红叶石楠、红豆杉、海桐、月季、雪松、柏类等。对于生根困难的个别落叶树如银杏,也宜采用嫩枝扦插的办法。嫩枝扦..嫩枝扦插是指在苗木的生长季节,采用当年生半成熟的枝条作为插条的扦插方法,它主要适用于常绿和半常绿木本花卉。如茶花、杜鹃、金叶女贞、桂花、罗汉松、红叶石楠、红豆杉、海桐、月季、雪松、柏类等。对于生根困难的个别落叶树如银杏,也宜采用嫩枝扦插的办法。嫩枝扦插的具体操作方法是:在苗木生长旺盛季节,剪取当年生半木质化枝条,按2节至4节(一片或一对叶为一节)为一段,每段长约10厘米左右,上面保留1至2片叶,下部去掉1至2片叶。叶片大的树种如茶花、桂花、石楠可将叶片剪去1/2,然后将插条下端剪或者削成斜口,再将插条按几十根一把用绳子扎好,最后将插条均匀粘上由干净黄土加杀菌剂、生根剂和水调配成的泥浆,待泥浆稍干后即可到备好的苗床进行扦插。嫩枝扦插要求苗床土要细碎、松软、平整,同时去除杂草和其他杂质,并对土壤喷药、消毒、杀虫。The softwood cuttage refers to the cutting method used in the growing season of the seedlings. It is mainly suitable for evergreen and semi evergreen woody flowers. Such as camellia, Rhododendron, Ligustrum lucidum, Osmanthus fragrans, pines, red leaf Shi Nan, yew, tung tree, rose, cedar, cypress, etc. Softwood cuttings should also be applied to individual deciduous trees such as ginkgo. The specific operation method of the cuttage is to cut the semi lignification branch of the year in the growing season, with 2 to 4 sections (one or one pair of leaves) as one section, about 10 centimeters long each, 1 to 2 leaves, and 1 to 2 leaves in the lower part. The leaves of large leaves such as tea, osmanthus and Photinia can be cut off 1/2, then cut or cut into the slanting mouth at the bottom, then the cuttings are tied up with dozens of ropes, and then the cuttings are evenly glued to the mud with a clean loess with fungicides, rooting agents and water, and the slurries can be made to the prepared bed after the mud is dry. Cutting. Softwood cutting requires that the seedbed soil be finely broken, soft and smooth, remove weeds and other impurities at the same time, and spray, disinfect and kill the soil.扦插深度为5厘米左右。扦插完毕后洒透水,插条叶面水珠干后立即在苗床再喷施一次农药杀菌杀虫,然后插上竹弓,盖上塑料薄膜,之后再插一些竹弓,在竹弓上面盖上黑色遮阴网。薄膜、遮阴网都要固定好。支撑遮阴网的竹弓比支撑薄膜的竹弓要高出15厘米至20厘米,以防遮阴网的热量传到薄膜里面,烫伤苗木。The cuttage depth is about 5 centimeters. After the cuttage, the water is sprinkled, and the leaf surface water drops immediately after the spraying of the insecticidal insecticide in the seedbed. Then the bamboo bow is inserted, the plastic film is covered, and then some bamboo bow is inserted, and the black shade net is covered on the bamboo bow. The film and shading network should be fixed. The bamboo bow supporting the shading net is 15 centimeters to 20 centimeters higher than that of the supporting membrane, in order to prevent the heat of the shading net from reaching the film and scalding the seedlings.至此,扦插工作全部完成。At this point, the cutting work is complete.扦插结束后,还要经常对苗床进行检查护理,查看苗床所盖薄膜、遮阴网是否被虫、鼠咬破,被风吹开。每隔15天左右揭开薄膜和遮阴网查看一次,并喷施农药杀菌杀虫,再重新将薄膜和遮阴网盖好。如果发现苗床土壤干燥则要在喷药之前先洒一些水,待叶面水干后再喷农药。一般揭膜喷药2次至3次后,插条就已生根成活,之后可隔1至2个月打一次药。插条成活后可考虑揭膜。在正式揭膜之前,要选择阴雨天,先揭开苗床一头或两头的薄膜通风炼苗数日,再全部揭掉薄膜。揭膜后遮阴网仍要覆盖。上半年扦插的苗木,遮阴网一直盖到晚秋才能揭掉,因为嫩苗经不起强光曝晒。特别值得一提的是金叶女贞、金森女贞是易于感病的苗木,揭膜要及时,一般插后20天左右,有90%左右生根就可以开始炼苗揭膜了,揭掉薄膜后,马上要喷一次杀菌剂防病,7至10天喷一次,连喷3至4次即可。After cutting, check the nursery bed regularly to check whether the film covered by the seedbed and the shading net are broken by insects or rats and blown away by the wind. Every 15 days, the film and shading net will be exposed once again. Pesticide and insecticide will be sprayed and the film and shading net will be covered again. If it is found that the soil is dry, sprinkle some water before spraying, and then spray the pesticide after drying. Generally, after cutting the film 2 times to 3 times, the cuttings have been rooted and survived, and then they can be taken 1 to 2 months later. When the cuttings are alive, the film can be taken into consideration. Before uncovering the film, we should choose a rainy day. First, we can expose the seedlings in one or both of the beds for several days, and then remove the film. The shading net is still covered after the film is uncovered. In the first half of the year, the shading net of cuttings had been covered until late autumn because the seedlings could not withstand strong sunlight. Especially worth mentioning is the golden leaf Ligustrum lucidum, Higginson Ligustrum lucidum is easy to feel the disease of the seedling, the film should be timely, 20 days after the general insertion, about 90% of the roots can begin to start the film, after removing the film, immediately spray a fungicide to prevent disease, 7 to 10 days to spray once, Lian Zhen 3 to 4 times.苗木,花卉新闻中心aowl原创2018-06-19 16:08绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/583.htm一、杨树腐烂病发生症状。杨树干部和枝条是烂皮病发生部位。表现为干腐和(枯梢)枯枝两种类型。1.

Poplar cadres and branches are the sites of rotten skin disease. They are two types: dry rot and dead branches.1、干腐病:主要发生于主杆、大枝及分叉处。发病初期是暗褐色,水渍病斑,略肿胀,皮层组织腐烂变软,皮下有酒糟味,以手压之有水渗出,后失水下陷,有时病部树皮溃裂,甚至变为丝状,病斑有时有明显的黑褐色边缘。在适宜条件下,纵向扩展较横向快。当病部包围树干一周时,其以上部分即行枯死,皮层腐烂,纤维分离如麻状,易自木质部边材也变色。后期病斑上生出许多针头状大小突起,即病菌分生孢子器。潮湿天气时,自分生孢子器孔口挤出黄色、橙色或红色卷丝状分生孢子角。1, dry rot disease: occurs mainly in main stem, big branch and bifurcation. Early onset is dark brown, water stains, slightly swollen, cortex tissue decay and soft, subcutaneous wine distillers taste, water exudation in the hand, and then the fall of water, sometimes the bark of the disease and even filamentous, and the spots sometimes have obvious black brown edges. Under suitable conditions, the longitudinal expansion is faster than that in the transverse direction. When the disease department surrounds the trunk for a week, the above parts will be withered away, the cortex will rot and the fibers will be separated from the wood. There are many needles in the later stages of the disease, namely the conidia. In wet weather, conidia openings of yellow, orange or red filamentous conidia can be extruded.2、枯梢病:主要发生在苗木,幼树及大树枝条上。发病初期呈暗灰色,病部迅速扩展,环绕一周后,上部枝条枯死。2. Stem blight: occurs mainly in seedlings, saplings and branches. The early stage of the disease was dark grey, and the disease rapidly expanded. After a week, the upper branches withered away.二、杨树腐烂病病源及发病规律Two, the source and regularity of the disease of poplar rot该病害主要是子囊菌亚门的污黑皮壳菌,其无性型为半知菌亚门的金黄色壳囊孢菌。以菌丝体和未成熟的子实体在病组织内越冬。越冬病斑内产生分生孢子器和成熟的分生孢子,成为当年侵染的主要来源。翌年4月开始发病,5月下旬至6月形成第一个发病高峰。7-8月气温增高时病势减缓,9月出现第2个发病高峰,此时病菌来源于当年春季病斑形成的分生孢子,10月以后停止。春季气温达10℃以上,相对湿度在60%以上时,病害开始发生;24-28℃时最适宜发病。病菌从伤口或皮孔进入,潜育期约1个月。从发病到形成分生孢子期需要2-3个月,秋季在病斑上形成囊腔和子囊孢子。潜伏侵染是杨树溃疡病的重要特点,子囊孢靠风力传播至寄主皮层上,由伤口侵入,过冬后再显病症。当树势衰弱时,有利于发生病害。当年在健壮的树上发病的病斑,翌年有些可以自然愈合。同一株病树,阳面病斑多于阴面。未移植的苗木一般不发病或病害很轻。一经移植,水分失去平衡,树势衰弱,病害便易于发生。春季发病高峰是前年秋季侵染造成的结果,而不是当年春季侵染的缘故。春季造林时,初定植幼林上的新病斑也是头年在苗圃感染所致。所以,苗木带菌数量与新林地幼树的发病程度密切相关。干旱瘠薄的立地条件是发病的重要诱因,也是我国干旱和半干旱的“三北”地区溃疡病特别普遍而严重的主要原因。起苗时大量伤根和造林时苗木大量失水,是初栽幼树易于发病的内在原因。杨树的不同种类及品系对溃疡病的抗性有明显差异。白杨派树种抗病,黑杨派树种抗性中等,而青杨派树种则多易感病。青杨派与黑杨派树种的杂交品系绝大多数也是较易感病的。青杨、小青杨、群众杨、北京杨都是高度感病的杨树。在抗病的派别中,有的品系是感病的,如毛白杨是较抗病的树种,其中有些品系(三倍体毛白杨)却十分感病。在感病类型中也有抗病品系。同时,树种的感病性与其所在环境条件关系也非常密切。The disease is mainly asexual fungus, asexual type, and its asexual type is golden yellow cyst fungus. It overwintered in mycelia and immature fruiting bodies in disease tissues. The conidia and mature conidia were produced in the disease spots of overwintering, which became the main source of infection in the year. The onset of the disease began in April of next year, and the first peak occurred from late May to June. When the temperature increased in 7-8 months, the disease slowed down. In September, there were second peaks of disease. The pathogen came from the conidium formed in the spring disease spot in the year of the year, and stopped after October. When the temperature is above 10 C in spring and the relative humidity is above 60%, the disease will begin to occur. It is the most suitable onset at 24-28 C. The pathogen enters from the wound or lenticels, and the incubation period is about 1 months. It takes 2-3 months from onset to formation of conidia. Latent infection is an important characteristic of poplar canker. The sporospore transmitted to the host cortex by wind force, invaded by the wound, and showed symptoms after winter. When the tree is weak, it is beneficial to the occurrence of disease. The disease spots on the strong tree in those years could heal naturally. In the same disease tree, the disease spots on the Yang face are more than the shady side. Untransplanted seedlings usually do not develop diseases or diseases are very light. Once transplanted, the water is out of balance, and the tree is weak. The peak of spring is the result of infection in autumn, but not in spring. During spring afforestation, new disease spots on young plantations were also caused by infection in nursery gardens. Therefore, the number of bacteria carrying seedlings is closely related to the incidence of new woodland young trees. The arid and barren site condition is an important cause of the disease, and it is also the main cause of the ulceration in the arid and semi-arid area of the "Three North" areas. A large number of seedlings were damaged when the roots were damaged and the seedlings were damaged. The resistance of poplar varieties and strains to canker disease is different. The poplar tree species are resistant to disease, while the poplar tree species are moderately resistant, while the poplar tree species are susceptible to disease. The vast majority of hybrid strains of Cathay poplar and black poplar species are also susceptible. Poplar, poplar, Populus Populus and Beijing poplar are highly susceptible poplars. Among the resistant groups, some strains are susceptible. For example, white poplar is a more resistant tree species. Some strains (triploid Populus tomentosa) are very susceptible. There are also disease resistant strains in the type of sense of disease. At the same time, the disease susceptibility of tree species is closely related to its environmental conditions.杨树新闻中心aowl原创2018-05-30 17:32绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/582.htm1.适当遮阴 对于耐荫树种和花卉及播种期过迟的苗木,在生长初期要采用降温措施,减轻高温热害的不利影响,如搭荫棚等,有条件的可采用遮阳网,避免日灼危害苗木。1. appropriate shade for shade tolerant trees and flowers and late sowing time seedlings, in the ea..1.适当遮阴 对于耐荫树种和花卉及播种期过迟的苗木,在生长初期要采用降温措施,减轻高温热害的不利影响,如搭荫棚等,有条件的可采用遮阳网,避免日灼危害苗木。1. appropriate shade for shade tolerant trees and flowers and late sowing time seedlings, in the early growing period, the cooling measures should be adopted to reduce the adverse effects of heat damage at high temperature, such as shading and so on, and the sunburn net can be used to avoid sunburn harm to the seedlings.2.适时松土除草 在每次降雨或灌溉后要进行松土除草。松土宜浅,保持表土疏松,以利于苗木生长。除草宜“除早、除小、除了 ”,撒播苗不便除草和松土,可将苗间杂草拔掉,再在苗床上撒盖一层细土,防止露根透风。松土要逐次加深,但要注意不伤苗、不压苗。2. timely loosen the soil to remove weeds. After every rainfall or irrigation, loosen the soil and weed. Loose soil should be shallow to keep the surface soil loose, so as to facilitate seedling growth. Weeding should be "early, except for small, except", the sowing seedlings are inconvenient for weeding and pine soil, and the weeds can be pulled out between the seedlings and then a layer of fine soil is covered on the seedbed to prevent the rooting from the wind.

Other emergency measures for wind and wind resistance before typhoon are used as auxiliary measures for tree pruning. Other emergency measures on the eve of typhoon, combined with pre wind pruning, wind resistance and wind resistance are as follows: 1, on the eve of the typhoon, the vertical pillar should be carefully checked and strengthened, and the pillar which does not conform to the requirement of wind protection and its tie and tie situation It should be corrected in time. 2, the binding is generally appropriate to use 8# lead wire or rope to bind the branch, and the binding point should be lined with rubber or other cushioning, so that the bark and branches will not be damaged by the shaking of the typhoon. The end of the binding must be fixed. 3. When the soil in the cavern is low and water is accumulated, it is necessary to add soil before the arrival of the typhoon, so that the soil around the root neck is made of steamed bread, which is beneficial to drainage. 4, the plant which is seriously inclined to the tree body should be restored before the typhoon is attacked and set up the pillar. At the same time, after the typhoon, the trees that have been tilted or fallen because of the typhoon should be timely and cultivated. 5. Pile driving pile is an emergency measure. It is mainly to cross the tree stump at the base of the trunk of the windward lane, and use the side stone on the sidewalk to cut the tree stump into the length of the tree trunk and the side stone, so that the tree pile ends at the base of the trunk and the top is on the side stone. The main points of pruning of various tree species: 1. The main anniversary of palm plants is regular pruning. The emphasis is on the removal of dead leaves, old leaves, drooping leaves and nuts, and the protection of leaf sheath. For the prevention of typhoons above 12 levels, especially in the windward area, the palms can be cut off or cut off part of the leaves to be extracted. High wind resistance of high tree body. Two. The basic requirements for wind resistance of arbor tree species are to ensure that the main trunk of the tree body is unbiased and the main branch is evenly distributed, and 3-5 strong, upward and upright branches are generally retained, and the weak branches, withered branches, the inside branches, the overdense branches, the Cross branches, the long branches, the branches, the branches of the sick and the insects and the improper positions of the pests are formed to form the wind resistance. The ratio of secondary branches to main branches was less than 0.7, keeping the crown neat and the trees ventilated and translucent. 1, tall tree trees such as tall trees, tall trees, luxuriant branches and leaves, trees are fine leaf banyan, Gao Shanrong, bodhi tree, Huang Ge banyan, neem, red sandalwood, autumn maple, camphor, brandy, olive, May tea, kapok, and other trees, such as green kapok. The general control height of these trees is 8-10 meters, and the crown size is in order. The general control is about 6 meters. 2, medium arbor tree species include neerneah, Hainan red bean, red flower Bauhinia, sheeps hoof nail, fragrant incxiang, long leaf manhu oil, various wind SUZUKI, shield column wood, black ink, mango, iron knife, arthauea, flame wood, banyan and other trees, the height of pruning is generally controlled to 6-8 meters, the crown is in order, generally controlled in 4. -5 meters.雷竞技新闻中心aowl原创2018-05-07 15:37绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/579.htm花卉苗木产业与旅游的结合点The combination of flower and seedling industry and Tourism1One打造三个大场面,收好门票Make three big scenes and collect tickets花卉苗木旅游多是以观光作为吸引游客的敲门砖,门票经济是主要收入类型之一。Flower and tree tourism ..花卉苗木产业与旅游的结合点The combination of flower and seedling industry and Tourism1One打造三个大场面,收好门票Make three big scenes and collect tickets花卉苗木旅游多是以观光作为吸引游客的敲门砖,门票经济是主要收入类型之一。Flower and tree tourism is mostly a tourist attraction, and ticket economy is one of the main income types.植物观光有一个弊端,There is a malpractice in plant sightseeing.就是容易产生审美疲劳,It is easy to produce aesthetic fatigue,这就需要我们打造三个大场面。This requires us to create three big scenes.◇ 要体现花卉苗木景观的大气壮观;To show the magnificent atmosphere of the landscape of flowers and seedlings;◇ 要展示视觉上的震撼力和冲击力;To show the visually shocking force and impact force;◇ 要通过不同的角度塑造立体化、多维度的观赏结构,如樱花开得灿烂、月季花开得绵长、三角梅开得热烈,各种植物加以搭配,映衬山峦、湖水、高低起伏的地势,将形成色彩缤纷的大地景观,组织卡丁车、亲子农场等体验活动,一幅幅生动画面跃然天地间,引人流连忘返。Through different angles, we should shape the stereoscopic and multi-dimensional ornamental structure, such as the bright blossom of cherry blossoms, the long bloom of the rose, the warm of the triangle, the collocation of various plants, the mountain range, the lake water, the high and low terrain, the colourful landscape of the earth, the experience of organizing the carting car, the family farm and so on. Activities, a vivid picture of the sky and earth, attracting people to linger on.2Two利用三个黄金时段,把门票经济放大Take advantage of three prime time periods to magnify the ticket economy花木旅游的三个黄金时段分别为春天、夏天、秋天,正所谓春赏花、秋赏树、夏观景。The three prime periods of flowers and trees tourism are spring, summer and autumn. They are called spring flowers, autumn trees and summer scenery.发展花木旅游,有两点需要注意,避免多种树少种花和只观光不休闲,也就是说要着眼于景观延展性和消费释放。利用好这三个黄金时段,更需要解决季节性差异问题,这是旅游产业的特性之一,落实到花木旅游,则要做到“旺季更旺、旺季拖长、淡季淡化”。To develop flower and tree tourism, there are two points to note: avoid planting flowers and sightseeing instead of leisure, that is to say, we should focus on landscape extension and consumption release. It is one of the characteristics of the tourism industry to make use of the three golden period of time, which is one of the characteristics of the tourism industry. To carry out the flower and tree tourism, we should make "the peak season is more prosperous, the peak season is long, the off-season desalination".3Three做好三方面业态规划,延长产业链Do a good job in three aspects of business planning and extend the industrial chain三方面业态规划主要指将季节优势做到极致、将淡季保养做到合理、将产量过剩合理调节。In the three place, the format planning mainly refers to the seasonal advantages, the reasonable maintenance of off-season, and the reasonable regulation of excess production.关于解决季节性差异的问题,上面已经介绍过,这里主要讲一下产量过剩如何调节。传统花木产业主要是对接房地产、城市建设、城市公园等传统需求,但休闲类旅游景区,包括一些5A景区创建,对景观都有比较高的要求,所以花卉苗木企业要主动和旅游行业做一些接口,以在原有产业渠道基础上实现更大的延展。As for the solution of seasonal differences, the above has been introduced. Here is mainly about how to regulate excess production. Traditional flower and tree industry is mainly the traditional demand of docking real estate, city construction and city park, but leisure tourist attractions, including some 5A scenic spots, have high requirements for the landscape, so the flower and seedling enterprises should make some interfaces actively with the tourism industry in order to achieve greater extension on the basis of the original industrial channels.

How can we check the survival of trees after planting trees?几乎所有的施工人员都知道苗木问题要及时..一、乔木种植后如何检查才能确认苗木是否成活?乔木种植后如何检查才能确认苗木是否成活?First, how can we check the survival of trees after planting trees? How can we check the survival of trees after planting trees?几乎所有的施工人员都知道苗木问题要及时发现,及时处理,但往往很多施工单位都是在苗木枯萎死亡后才发现。在此,我们希望施工人员能重视施工后的检查,及早发现问题进行解决,提高苗木的种植成活率。Almost all construction workers know that seedling problems should be found and handled in a timely manner, but many construction units are found only after the seedlings withered and died. Here, we hope that the construction workers can attach importance to the inspection after construction, find out the problems early, and solve them, so as to improve the survival rate of seedlings.解决方法:Resolvent:1.了解苗木的情况,是否山苗,泥球大小,运输时间,种植季节等。1. understand the situation of seedlings, whether mountain seedlings, mud balls size, transportation time, planting season.2.了解土方情况,是否深土层,PH值,土壤密实度,是否积水等问题。2. know about earthwork, whether it is deep soil, pH value, soil compactness, water accumulation and so on.3.用手有意识地推动树杆,看泥球与土壤是否结合紧密。3. consciously push the tree bar with your hands to see if the mud ball is closely linked to the soil.4.检查是否种植过深或泥球表面覆土过多,以免造成根系窒息死亡。4. check whether planting too deep or mud ball surface overburden, so as not to cause root asphyxia death.5.检查大型乔木是否有支撑或支撑是否牢固。以免大风吹杆造成根部松动,与土壤分离,致使树木死亡。5. check whether there is support or support for large trees. In order to prevent the roots from loosening and separating from the soil, the trees will die.6.检查树杆及枝条是否有破损或修剪方法不当,以免病菌从伤口倾入树体内,造成树木衰弱。6. check whether there are any breakage or pruning methods for tree stems and branches, so as not to let bacteria enter the trees from wounds and cause trees to weaken.7.观察树体上部情况,叶片是否有卷曲枯萎或非正常脱落,如有应及时用掏洞法查看根系情况,是否有腐烂,腐烂到何种程度,再来考虑是否能救活。因为根的好坏是树木成活的关键。7. to observe the upper part of the tree body, whether there is curly withering or abnormal shedding of the leaves, for example, it is necessary to use the hole method to check the root system in time, whether there is decay, to what extent, and to consider whether it can be saved. Because the quality of the root is the key to the survival of the trees.关键点:Key points:有问题及时掏洞看根系情况。There is a problem in time to dig holes in the root system.二、种植山苗为什么容易死亡?Two, why is the planting of a mountain seedling easy to die?一般的施工人员都知道山苗种植成活率很低,但是随着大乔木的日渐减少,尤其是个别大乔木苗圃已难觅,所以不得不用山苗。The ordinary construction workers know that the survival rate of the seedlings is very low, but with the growing decline of big trees, especially the big tree nursery is difficult to find, so it has to use the mountain seedlings.分析原因:Analysis of the reasons:1.由于环境的因素决定了山苗大多是直根系,长期依靠一个主根或多个主根向下生长。如果移植,主根切断,树体自身的水养分流失,根压减小,不能吸收土壤中的水养分而导致死亡。1. as a result of environmental factors, most of the seedlings are direct roots, which rely on a main root or a number of main roots for a long time. If transplanted, the main root will be cut off, and the nutrient loss of the tree itself will be reduced, and the root pressure will decrease.2.山上土层较薄,树木间的生存竞争使得树木的根系扎根很远,如果移植,能带的有效须根很少。2. the mountain soil is thinner, and the competition among trees makes the roots of trees far rooted. If transplanted, the effective fibrous roots of the trees are very few.3.一般山上的生长环境较好,水份充足,湿度较高,排水又好,土壤多偏酸性,较适合苗木生长。如果移植,苗木不能及时适应种植地的环境。3. generally, the growth environment of mountains is good, water is abundant, humidity is high, drainage is good, and soil is more acidic, which is suitable for seedling growth. If transplanted, seedlings can not adapt to the planting environment in time.4.山上的土壤多混有石块,所以苗木起挖,打泥球技术难度很大。4. the soil on the mountain is mostly mixed with stones, so it is very difficult to dig up the seedlings and make mud balls.解决方法:Resolvent:1.移植前半年最好先做好切根和树冠修剪工作。1. in the first half of the year, root cutting and crown pruning should be done first.2.起苗时注意保护泥球的完好不损伤,粗大根拔起而不是切断,保证树体的水养分的流失。2. when the seedlings are raised, pay attention to protecting the mud balls intact and not damaging. Coarse roots are pulled out rather than cut off, so as to ensure the loss of nutrients in the trees.关键点:Key points:粗大根不要切断。Do not cut off the thick root.苗木,园林,雷竞技,园林雷竞技新闻中心aowl原创2018-04-23 16:30绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/575.htm(l)绿篱的培育 矮篱培育要从最小植株开始。要选那些又矮又粗的植株,不选又高又细的植株,一般株距5一13cm通常是大叶子的灌木比小叶子灌木种植密度要小些。栽植后的前一、二年的首要任务是增加植株的宽度。如果植株基部没有长出足够的枝条,在栽种时或生长季的前几周,..(l)绿篱的培育 矮篱培育要从最小植株开始。要选那些又矮又粗的植株,不选又高又细的植株,一般株距5一13cm通常是大叶子的灌木比小叶子灌木种植密度要小些。栽植后的前一、二年的首要任务是增加植株的宽度。如果植株基部没有长出足够的枝条,在栽种时或生长季的前几周,要根据设计的绿篱高度来修剪(有的矮篱在离地15一30cm处短截),为了促进绿篱下部枝条生长,从水平方向发出的新枝不要剪掉太多。植株下部的枝条不能疏除,如果剪掉这些下部枝条会从修剪处形成直立枝,将在树篱的下端留下缺口,形成“光腿”现象。 随着绿篱在前三年中的生长,当新生长的直立枝比上一次修剪时的高度又长了15一30cm时,应剪掉其长度的1/2。同样,下部的枝条,一般不要剪去,随着植株下部的填满,变得比顶部更宽。 对于高篱,要防止下部枝叶干枯脱落。高篱种植后必须将顶部剪平,同时再将侧枝一律剪短,大大缩短营养的运输距离,也增强了各枝顶端对上行营养液的拉力,有利于养分向全树各部均匀分配,从而增加芽的萌发力,克服枝条下部“光腿”现象。每年在生长季均修剪一次,直至达到高篱要求为止。 (2)绿篱的维护 自然式绿篱的修剪可在任何时候进行,但在北方地区常绿阔叶绿篱的秋季修剪不得晚于“白露”之前,否则剪后萌发的新梢容易产生冻害。一般在春天新的生长开始前进行,剪后的空隙会很快被填满。自然式绿篱的维护通过回缩,或仅对最长的枝条进行短截,在绿篱外缘向内的15 -45cm短截,较短的枝条完整保留了下来,修剪后的绿篱外缘自然,对绿篱进行整形,使下部比上部宽,以便有足够的阳光照到下部的叶子上。(L) the cultivation of hedge hedge cultivation should start from the smallest plants. To choose those dwarf and coarse plants, and not to choose high and thin plants, the general plant spacing of 5 13cm is usually smaller than the small leaf shrub. The primary task of the first one or two years after planting is to increase plant width. If the plant base does not grow enough branches, in the first few weeks of the growing season or the growing season, it should be pruned according to the designed hedgerow height (some short hedges short at 15 30cm from the ground). In order to promote the growth of the lower hedgerow branches, the new branches from the horizontal direction should not be cut off too much. The branches in the lower part of the plant can not be removed. If the lower branches are cut off, the erect branches will be formed from the pruning, leaving a gap at the bottom of the hedgerow to form a "light leg" phenomenon. With the growth of hedge in the first three years, when the newly grown upright branch is 15 30cm longer than the last trimming, the 1/2 of its length should be cut off. Similarly, the lower branches should not be cut off. They will be wider than the top when they are filled up. For high hedges, it is necessary to prevent dry and shedding of lower branches and leaves. After high hedgerow, the top must be cut flat, and the lateral branch should be cut short at the same time, which greatly shortens the transportation distance of the nutrition and strengthens the pulling force of the upper nutrient solution at the top of each branch, which is beneficial to the distribution of nutrients to the whole tree, thus increasing the germination force of the bud and overcoming the "light leg" phenomenon in the lower branches. They are pruned once a year in the growing season until they reach high hedges. (2) the hedgerow maintenance of the natural hedgerow can be pruned at any time, but the evergreen hedgerow in the North should not be pruned later than "White Dew", otherwise the new shoots that germinate after the cut are prone to frost damage. Usually in spring, before the new growth starts, the gap will soon be filled. The maintenance of the natural hedgerow by retracting, or only the shortest cut of the longest branch, 15 -45cm short cut inside the outer edge of the hedgerow, the shorter branches completely preserved, the hedgerow outer edge of the trimmed nature, the hedgerow plastic, so that the lower part is wider than the upper part, so that there is enough sunlight to the leaves below.苗木,绿篱类苗木新闻中心aowl原创2018-03-28 15:47绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/573.htm棕搁在早春开花,10一U月间当果皮上出现白粉时种子成熟;用钦刀砍下果枝后把果皮晾干,与湿沙混合沙藏一冬。来年早春筛掉沙子,将果实故人草木灰水中浸泡3—5天,捞出后堆积3—4天,然后搓肄果皮和种子外面的蜡胶。用50℃温水浸泡一昼夜,捞出后直接播人露地苗床,覆土厚..棕搁在早春开花,10一U月间当果皮上出现白粉时种子成熟;用钦刀砍下果枝后把果皮晾干,与湿沙混合沙藏一冬。来年早春筛掉沙子,将果实故人草木灰水中浸泡3—5天,捞出后堆积3—4天,然后搓肄果皮和种子外面的蜡胶。用50℃温水浸泡一昼夜,捞出后直接播人露地苗床,覆土厚3厘米,盖上稻草保温保湿;在20℃以上的气温下刃天后开始出苗。 棕桐幼苗出土后生长极为缓慢,当年只能长出3厘米长的一枚针状叶,3年后才开始长出于茎和掌状叶,幼苗伯晒、怕早、怕冻,应搭设荫棚防护,保持土壤湿润。我国江南地区入冬后需盖革防寒。生长3年移栽一次,6年后出圃。 棕搁在我国南方地栽时.只要地面不低洼积水并有1米深的土层都能我活c起苗时尽量多带须根,栽植不要过深,否则容易烂心。五年生的植株可以盆栽,8一10年后应栽人木柄p20年后植栋生长缓慢,干茎不再加租,新叶萌发迟缓,应当淘汰。Palm flower in the early spring 10, a month when U appeared on the white pericarp of seed maturity; titanium cut fruit peel after dry and wet sand mixed sand reservoir in winter.

And then full field irrigation, and add a proper amount of octanoic acid, phosphorus, to prevent pests. 2, seed treatment, in order to improve the germination rate of lavender seeds, before sowing, should be soaked, first soaked with water for 12 hours, and then soaked with gibberellin for 6 hours. Gibberellin must be dissolved with a high degree of alcohol or alcohol, and the ratio of gibberellin to 4 pounds per gram. 3, sowing covers the soil, in order to sow evenly, we can seed a pot of fine soil mix, and then sow. Then cover the soil and cover the soil evenly, whichever is 2-3 times the size of the seed. 4, insulation, plastic film covering the entire furrow moisture, prevent shading with direct light, the lunar August and September temperature around 20 degrees, may emerge for 5-6 days, 7-8 days were all basic. 5, seedling management after refining, lavender seedlings, we will remove the plastic film with shading and spraying, antiseptic prevent rotten seedlings, generally with a fine and a bag of water against the bacteria. Sunny 15 kg, three times at intervals of five days later. As the sprouts grow about 10 cm can be transplanted. The above method of planting lavender for years of experience summed up, for large acreage reference.雷竞技竞猜雷竞技,雷竞技新闻中心aoutmy原创2017-09-04 17:37绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/562.htm1、打孔透气:就是在草坪上扎些小孔以便为根茎提供充足的氧气。每年进行2-3次便可提高草坪质量。  2、松根:即从草坪地中除去死叶和农药残留物,让草自由呼吸,以减少真菌和疾病的感染机会。松根可在春秋两季各施一次。  3、修剪:每周修剪2-3次可以保持草坪质地密集..1、打孔透气:就是在草坪上扎些小孔以便为根茎提供充足的氧气。每年进行2-3次便可提高草坪质量。  2、松根:即从草坪地中除去死叶和农药残留物,让草自由呼吸,以减少真菌和疾病的感染机会。松根可在春秋两季各施一次。  3、修剪:每周修剪2-3次可以保持草坪质地密集、有弹性。但请注意修剪并非意味着修剪的过低,装饰草坪应保持在2-4厘米的高度,娱乐用草坪应在4-5厘米之间。若您觉得修剪草坪很麻烦,百绿集团还为您提供了低养护混合草坪种子,这种混合配比包括有特殊的育种材料和生长缓慢的草种。  4、除杂草:可采用化学或生物等不同方法解决。对于大多数草坪来讲,去苔是个大问题。造成长苔的原因通常是由于修剪的太低或营养不良或土壤的PH值不理想;也可能是因为日照不充足。这就需要选择其它的混合配比。去苔可选用硫酸亚铁,市场中有很多不同品牌的产品。  若杂草太多,就有必要翻地进行重新播种了。  5、施肥不难,每隔4周施一次肥即可,秋冬季则无需施肥。1. Puncture and ventilation: make holes in the lawn to provide sufficient oxygen for the roots. Two to three times a year can improve lawn quality. 2. Loose root: remove dead leaves and pesticide residues from the lawn and let grass breathe freely to reduce the chance of infection by fungi and diseases. Pine root can be used in the spring and autumn. 3. Trim: trim 2-3 times per week to keep the lawn dense and elastic. But please note that the trim does not mean that the trim is too low, the lawn should be kept at 2-4cm and the lawn should be between four and five centimeters. If you think mowing the lawn is troublesome, the green group also provides you with a low maintenance hybrid lawn seed, which includes special breeding materials and slow-growing grass seeds. 4. Except weeds: chemical or biological methods can be used to solve the problem. For most lawns, a trip to the moss is a big problem. The reason for the mossy is usually due to the low cut or poor nutrition or the poor PH value of the soil; Or it could be because of the lack of sunshine. So you have to choose the other mixing ratio. There are many products of different brands in the market. If there are too many weeds, it is necessary to replant the seeds. 5. It is not difficult to fertilize, and fertilize once every four weeks.雷竞技工程,雷竞技新闻中心aoutmy原创2017-08-14 17:23绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/561.htm1、 雷竞技施工期:1.

Before the construction of the earth, measures should be taken to temporarily encircle in order to avoid the damage caused by the actual and incineration. In order to prevent mechanical injury of trunk, bark, straw bag protection application. In particular, street trees sometimes need to make cushions because of replacing sideboards or tree holes. Lime and cement can cause soil alkalinity and damage normal growth of trees. Therefore, during the construction of the first tree with soil protection, a high 30 cm below the mound, to avoid the invasion of lime. If the cushion needs to be watered, it should be surrounded by trees or water. It is forbidden to pour lime and cement into the tree hole.2.表土的采取和复原土壤是花草树木生长的基础,土壤中的土粒最好是构成团粒结构。适宜植物生长的团粒大小为1至5毫米,小于0.01毫米的孔隙,根毛不能侵入。一般情况下,表土具有大量养料和有用的土壤团粒结构,而在改造地形时,往往剥去表土,这样不能确保植物有良好的生长条件,因此应保存原有表土,在栽植时予以有效利用。在表土的采取及其复原过程中,为了防止重型机械进入现场压实土壤,避免团粒结构遭到破坏,最好使用倒退铲车掘取表土,并按照一个方向进行,表土最好直接平铺在预定栽植的场地,不要临时堆放,防止地表固结。掘取、平铺表土作业不能在雨后进行,施工时的地面状况应该十分干燥,机械不得反复碾压。为了避免在复原的地面形成滞水层,平铺时要很好地耕耘。2., the adoption and restoration of topsoil is the basis for the growth of flowers and trees. The soil particles in soil are best to form aggregate structure. The suitable granule size for plant growth is 1 to 5 mm, less than 0.01 mm pore, hair cannot invade. In general, the surface soil has a large number of nutrients and useful soil aggregate structure, and when the terrain is reformed, the topsoil is often stripped off, which can not ensure that the plant has good growth conditions. Therefore, the original topsoil should be preserved and used effectively when planting. In order to prevent the heavy machinery from entering the field compacted soil and avoid the destruction of the structure of the pellet, it is best to use the backward shovel to dig the topsoil in order to prevent the heavy machinery from entering the compacted soil. Excavating and spreading the surface soil can not be carried out after rain. The ground condition during construction should be very dry, and the machine should not be repeatedly rolled. In order to avoid the formation of stagnant water layer in the restoration of ground tile to good work.园林,雷竞技施工,雷竞技,园林雷竞技新闻中心aowl原创2016-09-10 21:20绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/553.htm投标人购买标书后,应仔细阅读标书的投标项目要求及投标须知。在获得招标信息,同意并遵循招标文件的各项规定和要求的前提下,提出自己投投标人购买标书后,应仔细阅读标书的投标项目要求及投标须知。在获得招标信息,同意并遵循招标文件的各项规定和要求的前提下,提出自己投标文件。  投标文件应对招标文件的要求作出实质响应。符合招标文件的所有条款、条件和规定且无重大偏离与保留。  投标人应对招标项目提出合理的价格。高于市场的价格难以被接受,低于成本报价将被作为废标。因唱标一般只唱正本投标文件中的“开标一览表”,所以投标人应严格按照招标文件的要求填写“开标一览表”、“投标价格表”等。  投标人的各种商务文件、技术文件等应依据招标文件要求备全,缺少任何必须文件的投标将被排除中标人之外。一般的商务文件包括:资格证明文件(营业执照、税务登记证、企业代码以及行业主管部门颁发的等级资格证书、授权书、代理协议书等)、资信证明文件(包括保函、已履行的合同及商户意见书、中介机构出具的财务状况书等)。  技术文件一般包括投标项目方案及说明等。  除此之外,投标人还应有整套的售后服务体系,其他优惠措施等。  上述是投标人投标时制作投标文件应注意的基本问题。投标人另外还须按招标人的要求进行密封、装订,按指定的时间、地点、方式递交标书,否则迟交的投标文件将不被接受。  投标人应以合理报价、优质产品或服务、先进的技术、良好的售后服务为成功中标打好基础。但投标人还应学会如何包装自己的投标文件。如在标书的印刷、装订、密封等均应给评委以良好的印象。园林,园林工程新闻中心不详原创2016-08-23 18:02绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/552.htm过去,观赏草因没有花朵般的色彩和诱人的香味,未能引起人们的兴趣。然而,1980年英国园艺设计师Res-selPage打破了这一过去,观赏草因没有花朵般的色彩和诱人的香味,未能引起人们的兴趣。然而,1980年英国园艺设计师Res-selPage打破了这一传统观念,利用各种观赏草组成了清新自然、管理成本低的新型花园,并产生了良好的观赏效果。从此,观赏草获得了新生。  观赏草系列品种达400种,它在色彩、高度、幅度、形态等方面的变化十分广泛,给园林应用提供了取之不尽,用之不竭的素材。观赏草种类繁多,有的喜欢光照,有的喜欢遮阴,还有的喜欢炎热,因而可以用在不同的环境中。观赏草与其他观叶植物配置时,可以丰富视觉效果。如在玉簪周围,种植纤细的苔草;在叶片平展的常春藤中点缀些叶片垂落的观赏草,使得阔叶和细叶有一定的比例,能起到丰富植物种类,改变单一观赏形态的效果。  与花配置:在观赏草的群落中,点缀些花朵,能缓和不同色彩花朵之间的强烈反差,同时还可作为背景,映衬出花的鲜艳,使景观更增韵味。  与灌木配置:灌木是园林景观中不可缺少的植物,更多的被运用在定型植物方面。是一种整齐划一的景观风格,然而在某些应用案例中,也不免使人感觉生硬。在这种情况下,观赏草与灌木配置也能产生奇妙的观赏效果。温柔的观赏草,会用其纤细、随风舞动的叶,软化那些略显生硬的界面,也可以算是一种阴阳协调的组合。  观赏草与不同的草搭配所达到的效果不同。园林新闻中心不详原创2016-08-14 15:27绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/551.htm园林树木冬季养护工作直接影响园林树木翌年的观赏价值和经济价值。园林树木的冬季养护应注意以下几方面:园林树木冬季养护工作直接影响园林树木翌年的观赏价值和经济价值。园林树木的冬季养护应注意以下几方面:  一、及时灌冻水  园林树木的整个生命过程都离不开水。虽然冬季蒸发量小,需水量相对较少,但却影响到园林树木的抗寒能力和来年的生长发育。因此,应在11月初,对树木尤其是新栽植的树木灌一次水。也就是“灌冻水”,灌后结合封冻水,在树木基部培起土堆。这样既供应了树本身所需的水份,也提高了树木的抗寒力。  二、施肥  秋后树梢停止生长后,根系又出现一次生长高峰。因此,应于秋末冬初视树龄大小和栽植时间的长短,适当施一些有机肥或化肥,且适量灌木,使肥料渗入,以促发新根,增强树势,为来年的生长发育打好基础。  三、整形修剪  根据园林树木不同的应用目的,进行正确的整形修剪,既可调整树形,还可协调地上地下部分之间的关系,促进开花结果,又可消灭病虫害。可在“冬至”前后进行此项工作。如果量大,可延至春节前后,根据树木的生长特性,将枯死枝、衰弱枝、病虫枝等一并剪下,并对生长过旺枝进行适当回缩,改善树冠内部的通风透光条件,培养理想的树形,对于较大的伤口,用药物消毒,并涂上铅油加以保护。  四、树干涂白  冬季树干涂白既可减少阳面树皮因昼夜温差大引起的伤害,又可消灭在树皮的缝隙中越冬的病虫。涂白剂配方为生石灰10份,食盐1份,硫磺粉1份,水40份,可于11月份进行此项工作。  五、伐挖死树  由于各种不同的原因,如树木衰老,病虫侵袭、人为破坏等,造成一些树木死亡,破坏了整体景观,影响市容市貌。可利用空闲时间,对那些无可挽救的树木,尽早伐除,并补栽上相同规格的苗木。  六、清理杂草落叶  杂草落叶不仅是某些病虫害的越冬场所,而且在干燥多风的冬季易发生火灾。因此,应把绿地中的杂草落叶清理干净,集中处理,既消灭了病虫源,也消除了火灾隐患。园林,园林树木新闻中心不详原创2016-07-15 19:39绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/550.htm研究工程综合说明,以对工程作一整体性的了解。一、研究招标文件  资格预审合格,取得招标文件,即进入投标前的准备工作阶段。  1.研究工程综合说明,以对工程作一整体性的了解。  2.熟悉并详细研究设计图纸和技术说明书,使制定施工方案和报价有明确的依据。对不清楚或矛盾之处,要请招标单位解释订正。  3.研究合同的主要条款,明确中标后应承担的义务、责任及应享有的权利。包括承包方式;开工和竣工时间及提前或推后交工期限的奖罚;材料供应及价款结算办法;预付款的支付和工程款结算办法;工程变更及停工、窝工等造成的损失处理办法等。  4.明确招标要求,在投标文件中要尽量避免出现与招标要求不相符合的情况。  二、调查投标环境  投标环境是招标工程项目施工的自然、经济和社会条件。投标环境直接影响工程成本,因而要完全熟悉掌握投标市场环境,才能做到心中有数。  主要内容包括:场地的地理位置;地上、地下障碍物种类、数量及位置;土壤(质地、含水量、PH值等);气象情况(年降雨量、年最高温度、最低温度、霜降日数及灾害性天气预报的历史资料等);地下水位;冰冻线深度及地震烈度;现场交通状况(铁路、公路、水路);给水排水;供电及通讯设施。材料堆放场地的最大可能容量,雷竞技材料苗木供应的品种及数量、途径以及劳动力来源和工资水平、生活用品的供应途径等。  三、投标策略  投标策略是能否中标的关键,也是提高中标效益的基础。投标企业首先根据企业的内外部情况及项目情况慎重考虑,做出是否参与投标的决策,然后选用合适的投标策略。  常见投标策略有以下几种:  1.做好施工组织设计,采取先进的工艺技术和机械设备;优选各种植物及其他造景材料;合理安排施工进度;选择可*的分包单位,力求最大限度的降低工程成本,以技术与管理优势取胜。  2.尽量采用新技术、新工艺、新材料、新设备、新施工方案,以降低工程造价,提高施工方案的科学性赢得投标成功。  3.投标报价是投标策略的关键。在保证企业相应利润的前提下,实事求是地以低报价取胜。  4.为争取未来的市场空间,宁可目前少赢利或不赢利,以成本报价在招标中获胜,为今后占领市场打下基础。  四、制定施工方案  施工方案是招标单位评价投标单位水平的重要依据,也是投标单位实施工程的基础,应由投标单位的技术负责人制。  1.施工的总体部署和场地总平面布置。  2.施工总进度和事项(单位)工程进度。  3.主要施工方法。  4.主要施工机械数量及配置。  5.劳动力来源及配置。  6.主要材料品种的规格、需用量、来源及分批进场的时间安排。  7.大宗材料和大型机械设备的运输方式。  8.现场水电用量、来源及供水、供电设施。  9.临时设施数量及标准。  10.特殊构件的特定要求与解决的方法。园林,园林工程新闻中心不详原创2016-06-22 14:03绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/569.htmFlower refers to herbaceous flowers, is an important landscape plant material.

Flower variety, high propagation coefficient, color rich, application in landscape greening has very high ornamental value and decorative effects. It can not only enhance the cover effect of the surface, but also form a unique plane composition with the ground to be combined with the ground. The value and characteristics of herbaceous flowers in the landscaping and beautifying of the garden can be highlighted by the use of artistic techniques.园林雷竞技中常用草花大致可分为传统品种和引进栽培品种两大类。传统品种有一串红、万寿菊、三色堇、金盏菊、金鱼草、石竹、美女樱、太阳花、美人蕉等。引进栽培优良品种有矮牵牛、非洲凤仙、矮生向日葵、杂交天竺葵、藿香蓟等。Common flower landscape can be divided into traditional varieties and introduced varieties of two categories. The traditional varieties of Salvia splendens, marigold, pansy, Jin Zhanju, snapdragon, carnation, Verbena, sunflowers, Canna etc.. The introduction of fine varieties of cultivated Petunia, African Impatiens, dwarf sunflower, hybrid geranium, ageratum etc..草花的园林雷竞技造景按照运用形式可分为草坪镶嵌、立体美化、花坛用花等几种。草坪镶嵌是指用草花在草坪的某些区域点缀或营造花境,使草坪更富色彩;立体美化主要是垂直雷竞技装饰,用草花制作成花柱、花球等园林小景;花坛用花一般采用几种草花搭配种植,可保证全年有花。现在还有一类新的应用方式,即草坪组花,采用15种以上的一年生和多年生草花混合而成,其中大多数一年生草花具有自播繁衍能力,多年生的草花可3年~5年不需要重新播种。因此草坪组花适应能力强,其建植、栽培、养护的成本很低,并且其色彩、花型多样,春、夏、秋季可连续开花,观赏期长,可广泛应用于公园、广场、道路、住宅小区和庭院的雷竞技美化。Flower garden landscaping in accordance with the application form can be divided into mosaic, landscaping, lawn stereo flower with flowers etc.. The lawn mosaic refers to flower in certain areas of lawn ornament or create a flower, make the lawn more colorful; three-dimensional landscaping is mainly vertical greening decoration with flower making style, flower balls and other flower garden king; flowers generally use several flower planting collocation, can ensure that the entire year there are flowers. Now there is a new class of applications, namely grass group of flowers, adopt more than 15 annual and perennial flower mixture, most of the annual flower has self reproduction ability, perennial flower can be 3 to 5 years without re seeding. Therefore, the lawn group has strong adaptability, and its cost of planting, cultivation and maintenance is very low, and its color and flower pattern are various. It can bloom continuously in spring, summer and autumn, and has long viewing period. It can be widely applied to landscaping and beautifying of parks, squares, roads, residential quarters and courtyards.草花在园林雷竞技中的配植和其他植物景观设计一样,必须做到景观与生态共生,美化与文化兼容,以展现草花的美丽形态和丰富内涵,使人们在欣赏时产生意境之美。使用草花造景时,在种类的选择上,既要在色彩、线条、质地及比例方面有一定的差异和变化,显示出多样性,又要使各类草花之间有一定的和谐性,保持统一。统一不仅包含内部的统一,而且包含外部的统一,整体景观艺术风格要与周围环境相协调。在较自然的环境中,可采用自然均衡布局;在广场、大门两侧摆放,则要采用规整布局,花柱、花球、花钵的摆放就要求规整对称。在配置中,有意识地将草花进行一些有规律的变化,会产生韵律感。The flower in the garden afforestation planting and other plant landscape design, must be landscape and Ecological Symbiosis, landscaping and culture, with beautiful flower form and rich connotation, make people enjoy the beauty of artistic conception in. The use of flower landscape, in the selection, not only have a certain difference and change in color, line, texture and proportion, showing diversity, harmony and make certain kinds of flower, maintain unity. The unity not only contains the internal unity, but also contains the external unity, the overall landscape art style should be coordinated with the surrounding environment. In a more natural environment, the balanced layout; placed in the square, on both sides of the door, want to use the regular layout, display style, bouquets, flower requires neat symmetry. In the configuration, consciously make some flower regular changes, will have a sense of rhythm.根据应用场合的不同,选择生态习性与之相适应的草花,能起到事半功倍的效果,而且节省养护费用。在建筑背阴处可选择摆放耐阴的花卉;在广场摆放草花时,考虑到是全光照,地面升温快,可选择一些耐干旱、喜光、管理粗放的草花品种,如万寿菊、一串红、长春花、太阳花、千日红等。According to different applications, select the ecological habits of the flower, can play a multiplier effect, but also save the cost of maintenance. In the construction of the shade can choose placed shade flowers; flower placed in the square, taking into account the full sunlight, the ground temperature quickly, can choose some drought resistant, light and extensive management of flower varieties, such as marigold, a string of red, Changchun flowers, sunflowers, globeamaranth etc..园林,雷竞技,园林雷竞技新闻中心aoutmy原创2016-06-13 21:21绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/568.htmGovernment procurement greening project involving seedling varieties selection, seedling quantity specifications, acceptance criteria, maintenance services, standard complex, especially the quality of green seedlings require long-term growth cultivat..Government procurement greening project involving seedling varieties selection, seedling quantity specifications, acceptance criteria, maintenance services, standard complex, especially the quality of green seedlings require long-term growth cultivation to appear, so greening engineering procurement is the difficulty of the work of government procurement. Based on some experience accumulated in the work, the author briefly explains several key links and problems that should be paid attention to in the procurement of greening engineering with ten requirements.一、时间要合理安排First, time should be arranged reasonably由于受自然条件的限制,对各种苗木栽植的具体时间要求也不相同,应该遵循自然界客观规律,根据项目预算合理安排采购时间、园林工程建设开工时间与完工时间。Due to the limitation of natural conditions, the specific time requirements for seedling planting are also different. We should follow the objective laws of nature, arrange procurement time according to project budget, start time and completion time of landscape engineering construction.二、苗木选择要认真研究Two. The choice of seedlings should be carefully studied应选择适合当地栽植的苗木,根据当地栽植的历史习惯、地段特征选择合适的苗种。对栽种区域土质、水质调研分析,筛选出适合生长的苗木品种。We should choose the seedlings suitable for local planting, and choose suitable seedlings according to the historical habits and characteristics of the local planting.

But if the lifting, transportation, transfer, management of a link handled properly, will affect the transplant survival rate, causing unnecessary losses.起苗准备起苗前7天,充分浇水,以防苗木脱水。对于表土板结的,由于浇水难渗到深层,应先在苗木根部周围土壤打几个小洞,让所浇的水渗透到植株的各个根群,补足水分,以避免起苗后苗木过早脱水而影响成活率。起苗前,喷施陪嫁肥,以提高苗木抗逆性和适应性,一般用磷酸二氢钾、多元叶面肥、光合微肥等的混合液喷施。For 7 days before transplanting seedling, well watered, to prevent dehydration of seedlings. The surface soil compaction, due to difficult to seep into the deep water, should be first in the seedling root soil around a few small hole, let the water penetration into various plant roots, supply water, to avoid premature dehydration after lifting seedling survival rate. Meanwhile, the dowry spraying fertilizer, in order to improve the stress resistance and adaptability of seedlings, the mixed liquid spraying foliar fertilizer, potassium dihydrogen phosphate, multiple photosynthetic fertilizer for general use.细致起苗对带土球不完整和根群伤口多的苗木,应用糊状黄泥浆蘸根后包装。包装时Careful on the ball is not complete and seedling root group wound seedlings, application of yellow mud paste dipping root after packing. Packing time,先用湿稻草包扎一层,然后用塑料薄膜包裹并用绳子捆扎结实。 定植前准备苗木运到后,应尽快开箱,把苗木竖起,稀疏放置,剪除徒长枝、病残枯老枝、密生弱小枝,其大伤口用蜡溶封,然后叶面喷施磷酸二氢钾、多元叶面肥或植物动力2003。First, wrap a layer of wet straw, then wrap with plastic film and tie up with a rope. Prepare to seedlings before planting, should as soon as possible out of the box, put the seedling erect, sparsely placed, cut off water branch, dry branch, dense sick old small branches, the wound with dissolved wax seal, and then spraying potassium dihydrogen phosphate, or multiple foliar fertilizer plant power 2003.整畦挖穴畦地土壤易板结的要加沙;太贫瘠的应填沃土,进行土壤改良。畦地是沙层的,应填保水性能良好的黄泥30厘米厚;低洼、排水不畅的畦地,应开凿排水沟,依次填上卵石、粗沙、细沙。定植穴应先灌足水,然后填入稻草、疏松沃土。The soil in the border area of the whole border is easy to add to the soil, and it should be too poor to fill the soil and improve the soil. The furrow is sand, should be filled with good water retention properties of soil 30 cm thick; low-lying, poor drainage basin, should be dug ditches in turn fill gravel, coarse sand, fine sand. The planting point should be filled with water first and then filled with straw and loose fertile soil.定植定植讲究原向定植,原向定植能使植株更好地适应环境,提高成活率。对于带土球不完整的苗木,根群已有不同程度脱水,需用蘸根浆(2%的磷酸二氢钾、2%的白砂糖、1%的维生素B12针剂、95%的黄泥浆)浸蘸。将苗木的根放入定植穴中,对准原向,理顺根系,填入一半的土,略提起苗木基部,让根系伸展,然后浇水,再填土至离穴面5厘米处,压实、浇足水。The original planting and planting can make the plant adapt to the environment better and improve the survival rate. The ball is not complete seedling root group have different levels of dehydration, by dipping the root pulp (2% phosphate, 2% sucrose, 1% vitamin B12 injection, 95% of yellow mud) dip. The seedling root on the concentration of planting hole, to the original alignment, straighten out the root, fill half of the soil, slightly lift seedlings base, let the root, and watering, then fill to 5 cm from the hole surface, compaction, water well.定植后护理大穴种植的单株大苗,定植后,应用木棍支撑,捆扎结实,以防风吹摇动,影响根与土的黏合而影响生根。当表土干白,要及时浇水。有霜冻的地区,穴土面要覆盖稻草保温;苗木主干用草绳缠捆,以防裂皮;株冠最好用塑料薄膜罩住并用绳子捆牢。Plant seedlings, planting nursing big hole after planting after planting, application of wooden poles, tied to strong wind shaking, effects of root and soil adhesion and rooting effect. When the surface of the surface is white, water should be watered in time. Frost area, point to the soil surface covered with straw insulation; seedling trunk with a rope wrapped in leather, crack; canopy covered with plastic film and best rope.苗木新闻中心aoutmy原创2016-05-31 19:34绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/566.htmThere are two situations in the watering of the seedlings of the seedlings.

Another is due t..There are two situations in the watering of the seedlings of the seedlings. One is pouring water from time to time because of the overindulgence of the flowers and plants, which causes the flowers to be waterlogged by too much water. Another is due to poor management, the month after month and year after year even a drop of water will not be careless with water, resulting in the death of drought. The following will ever experience summed up a flower watering for the novice should pay attention to more than 7 and seven little to share the first flower new friends. Let you in the days after the process of flowers, pouring over watering less aware.天旱多浇天阴少浇天气干旱,土壤容易失水,浇水要多而勤,小盆每日浇水2次,大盆每日浇水1次。The drought irrigates day overcast weather drought soil less water, easy to dehydration, watering to small basin and diligent, daily water 2 times, a large pot of daily water 1 times.旺盛期多浇休眠期少浇花卉生长旺盛期时需要大量的养分和水分,故应结合施肥多浇水、勤浇水;花卉休眠期时,生长趋于停滞状态,需水量很少,应严格控制浇水。During the vigorous period, multi cast and dormancy period need less nutrient and moisture when watering the flower growth period.

Experts said. The structure of flower seedlings planted in Henan, ornamental seedlings absolute position, fresh cut flowers, potted flowers and edible flower seedlings accounted for relatively low; in the industrial structure, planting industry output accounted for 89.1%, two or three industrial enterprises accounted for only 10.9%; single product, by assimilation phenomenon is serious, the product structural overcapacity issues outstanding, resulting in a lot of flowers seedling nursery stock sales difficult.一、转型I. transformation会议指出,今年,河南将重点抓好许昌鄢陵、信阳潢川、南阳卧龙、新乡获嘉、郑州近郊及惠济区的苗木花卉产业集群和产业基地建设,在科技 创新、标准化生产、社会化服务、市场化流通、品牌化建设、政策扶持等方面推进苗木花卉产业基地建设转型升级。同时,引导企业向生产标准化、专业化、规模化 和智能化转变,实现苗木花卉生产由劳动力、土地密集型向资本、技术密集型转变。The meeting pointed out that this year, Henan will focus on the flowers and plants industry cluster and industry base construction in Xuchang Yanling, Xinyang Huangchuan, Nanyang Wolong, Xinxiang Huojia, Zhengzhou suburbs and Huiji District, to promote innovation in science and technology, standardized production, social services, market circulation and brand construction, policy support and other aspects of the construction of flower seedlings the transformation and upgrading of industrial base. At the same time, guide enterprises to production standardization, specialization, large-scale and intelligent change, to achieve the production of nursery stock from the labor, land intensive to capital, technology intensive change.二、创新Two, innovation由于河南省从事苗木花 卉科研教学的机构较少,导致苗木花卉产业科技创新能力不足,这已成为制约全省苗木花卉产业持续健康发展的瓶颈。河南省苗木花卉协会会长何东成说,全省规模以上苗木花卉企业仅占总数量的21%,知名度高的苗木花卉龙头企业更少。会议建议,今后河南要加快培育自有技术和苗木花卉品牌,在产品的名、优、新 上取得新突破;加强苗木花卉种质资源收集保存、品种创新、技术研发和良种繁育示范基地建设,为花农提供更多有自主知识产权的新品种;不断加大科技投入,壮 大中端苗木花卉产业板块,打造高端苗木花卉中心链条。Due to the lack of scientific research and teaching institutions in Henan Province, the lack of scientific and technological innovation ability of nursery stock and flower industry has become the bottleneck restricting the sustained and healthy development of the flower and flower industry throughout the province. Henan province flower seedlings association chairman He Dong said that the flower seedling Enterprises above the scale of the province accounted for only 21% of the total land, the high visibility of flower seedlings less leading enterprises. The meeting recommended that the future of Henan to accelerate the development of its own technology and brand products in the flower seedlings, name, excellent, new new breakthroughs; to strengthen the collection and preservation of germplasm resources of varieties of flower seedlings, innovation, technology development and breeding demonstration base construction, provide more new varieties with independent intellectual property rights for farmers continue to increase; investment in science and technology, in the end of growing seedlings flower industry sector, to create high-end flower seedling center chain.三、融合Three, integration.统计显示,2015年,全省以苗木花卉为主题的休闲旅游接待游客6500万人次,实现综合收入48.8亿元。其中,鄢陵县推出春季 赏花、消夏采摘、花香茶韵、踏雪寻梅、花香农家乐等系列休闲游,全年接待游客421万人次,旅游综合收入达9.2亿元。对此,会议建议,今后苗木花卉产业 要与旅游、文化创意等产业相融合,以苗木花卉基地为载体,打造苗木花卉艺术主题公园和主题景区,开发苗木花卉观赏、游憩休闲、文化体验产业,形成苗木花卉 文化创意和苗木花卉旅游商品设计、加工、销售等花文化产业链,打造综合、混合发展新业态,培育新的增长点。Statistics show that in 2015, the provinces seedlings, flowers as the theme of leisure travel 65 million visitors, to achieve comprehensive income of 4 billion 880 million yuan. Among them, Yanling County launched the spring flowers, summer tea picking, flowers, flowers, taxuexinmei farmhouse leisure series, the year 4 million 210 thousand tourists, tourism revenue reached 920 million yuan. In this regard, the meeting suggested that in the future the flowers and plants industry should be combined with tourism, cultural and creative industries, to flower seedlings base as the carrier, to

最常使用于城市园林绿化中http://www.yjlvhua.com/news/543.htm冬季,园林工人经常会对行道树木进行修剪,以清除病虫枝、徒长枝,保持树姿优美。在修剪过程中常会在树体上留下伤口,特冬季,园林工人经常会对行道树木进行修剪,以清除病虫枝、徒长枝,保持树姿优美。在修剪过程中常会在树体上留下伤口,特别是对大枝进行回缩修剪易造成较大的伤口,或者因扩大枝条开张角度而出现大枝劈裂现象。另外,因大风和其他人力的影响也会造成树木受伤。这些伤口若不及时处理,极易造成枝条干枯,或经雨水浸蚀和病菌侵染寄生引起枝干病害,导致树体衰弱。针对伤口种类有以下几种不同处理方法。  一、修剪造成的伤口处理。在修剪中有时候需要疏枝,将枯死枝条锯平或剪除,在其附近选留新枝加以培养,以补充失去部分的树冠空缺。疏枝后树体上的伤口,尤其是直径2厘米以上的大伤口,应先用刀把伤口刮平削光,再用浓度为2%~5%的硫酸铜溶液消毒,然后涂抹保护剂。一般保护剂是用动物油1份、松香0.7份、蜂蜡0.5份配制的,将这几种材料加热溶化拌匀后,涂抹于树体伤口即可。  二、大枝劈裂伤口的处理。先将落入劈裂伤口内的土和落叶等杂物清除干净,再把伤口两侧树皮刮削至露出形成层,然后用支柱或吊绳将劈裂枝皮恢复原状,之后用塑料薄膜将伤处包严扎紧,以促进愈合。若劈裂枝条较粗,可用木钉钻在劈裂处正中钻一透孔,用螺丝钉拧紧,使劈裂枝与树体牢牢固定。如果劈裂枝附近有较长且位置合适的大枝,也可用“桥接法”把劈裂的枝条连接上,促进愈合,以恢复健壮的树势。若枝条损坏程度不是很严重,可借助木板固定、捆扎,短期内便可愈合,半年至一年后可解绑。被风将树干刮断的大树,可锯成1米~1.5米高的树桩,视树干粗细高接2至4根接穗,或在锯后把锯面切平刨光,消毒涂药保护后,让其自然发生萌蘖枝,逐渐培养成大树。  三、树洞的填补。有些树体上的伤口因保护不周导致愈合不良,引起树皮木质部腐烂,进而形成树洞。树洞严重时会破坏树体的输导组织,使水分和养分不能正常运转而危及树木生命。因此,必须及时采用补救措施,防止树洞继续扩大。可先将腐烂的木质挖出,并切削去全部腐烂组织,清理干净之后用消毒药水消毒,然后用水泥和小石子按1:3的比例混合填补。小树洞可用木板钉楔填平,或用沥青混合3至4份锯末,涂抹填平。  四、皮层腐烂的治疗。有些树木皮层严重受损但尚未环状烂通的主枝和主干,可在4月~6月实行植皮手术。先用酒精消过毒的刀片把损伤坏死的树皮皮层和木质部刮净,并对伤口进行消毒,之后沿病疤边缘向外削去3厘米~4厘米宽的一圈好皮。在同一品种树体的光滑健壮枝干上取一块健康树皮,大小和病树上伤疤部大小一致,将其贴于病树枝条上,使四周接触好,并紧贴木质部。植皮之后用塑料薄膜将伤处封严,防止雨水进入。园林新闻中心不详原创2016-05-09

www.zhongyifengliao.com www.dzyangguang.com.cn(4)根据施工任务量、施工要求、预算项目的具体定额等组织施工技术力量、安排施工计划、制定工程进度表。(5)熟悉图纸、熟记规范,准备好施工机械、工具以及花草树木、肥料等材料的来源,做好施工的前期准备工作。人员必须到位,工具必须足够,机械必须检修完好,花草树木必须符合要求、无病虫害,肥料要求合格。2.土方施工山水是中国园林的骨架。在园林建设中,首当其冲的工程就是地形的整理和改造,工程量较大,工期也较长,是建园的主要工程项目。在满足设计意图的前提下,如何尽量减少土方的施工量,减少一些不必要的土方浪费而造成投资上的浪费,做到节约投资和缩短工期,这就要对土方的挖、填、运进行必要的计算,做到心中有数、统筹安排,以提高工作效率和经济效益。(1)土方量计算。需要进行土方量计算的一般都是要堆土挖湖等较大土方量的情况,一般根据附有原地形等高线的设计地形图来进行。由于园林山水是要求具有自然效果的,不可能是规则的简单形状,我们在计算工程量的时候要力求准确,尽量把土方分解成越细越好(即把复杂地形分解成简单易算的简单图形),可减少误差。计算完堆土及挖湖的量后,统计所需土量或需运走余泥的量,寻找优质泥源和余泥堆放地。(2)土方放线。应按设计图纸的要求,用测量仪器在施工现场进行定点放线工作。为使施工充分表达设计意图,放线时应尽可能精确。如果湖、山的地形比较大,现场较难放线,这种情况下可先在施工图上打方格,再把方格网放到地面上,而后把设计地形等高线和方格网的交点,标到地面并打桩,桩木上标明桩号及施工标高。(3)土方工程施工包括挖、运、填、压四个内容。其施工方法又可分为人力施工、机械施工、人机混合施工。以人机混合施工最为普遍。对要求需要挖湖造山或如空中花园项目,根据图纸要求,与建筑、园建部门协调,把土方填到位,在空中花园项目中,若客土量较大(如厚度超过80cm)用机械压土会影响到楼板的承受力,应采取灌水方法让其沉降至所要求高程。(空中花园项目中,应先请专业公司做好防水、疏水、排水处理)。但无论如何,都要保证种植层疏松的要求。①挖湖。在施工前必须向有关部门了解清楚施工点情况,查清楚是否有地下管线或其它有影响施工的物件。然后才按图放线进行开挖,如果同时有堆山的,可考虑挖出的土是否适合利用(这可节约成本、缩短工期)。挖湖时还要注意湖底应平整有一定的倾斜度(一般有设计要求),以利排水。况下作些松土或少量换土、客土就基本可作雷竞技施工的场地。施工时要②堆山。如果山体体积比较大(如高超过3m),尽可能每堆约1.5m 厚度用机械碾压一次,以防下沉。如果山体高在3m 内,亦可用灌水方法让其沉降。但山体的种植层一定要求是疏松的种植土。③一般场地。即基本在原有地(而且是较平整)的情注意排水措施,熟悉设计图,先做好排水工程(如明沟或暗沟),将水引入市政管道。(4)雷竞技地平整及清理。①平地。种植地表应按预算定额规定在20cm 高差以内平整雷竞技地面,同时清除碎石及杂草杂物;种植场或草坪坡度可定在2.0%~3.0%之间以利排水。一般情况下,靠路边或路牙雷竞技地面应低于路边或路牙5cm以防泥水冲落路面,而且要将雷竞技地面水引至排水管井。但有种情况是路边为草地时要把水排出到马路排水沟的,草地边与路牙等高或略高于路牙,所以在实际施工中,要根据设计图和实际情况灵活掌握。②坡地。按设计高程图所定坡度整理,特别是造假山时要处理好峰、谷、涧的关系,一方面在功能上要有利于排水,另一方面在美观上要符合园林美感,细腻之处要用人工慢慢雕琢。力求从不同角度有不同的景观效果。(5)土质要求。PH 值要求为5.5~7.5 间壤土,不含建筑和生活垃圾;在种植层内不能有杂草。土质要疏松,有一定的土深:草地大于30cm,花灌木大于50cm,乔木则要求在种植穴周有大于50cm 的土壤(即一般在130cm 以上)。如果土壤不合要求(如酸碱度太大、垃圾杂质太多等等),就要进行换土。3.供电、供水施工因为园灯照明必须用电、雷竞技管理必须用水,而且水、电管线必须要埋在土层、道路、园林建筑下,因此我们要在种植之前,土方施工之后,园建、路建同步完成这些工作。必须指出的是水、电施工也要严格按图施工,有些经验不足的施工员会有这样的错误观点:水、电到位就行,不管水管、线缆的走向,依其施工方便。这种做法会造成很多不利后果:雷竞技种植或改造时不清楚管线而挖断,水、电维修时为了找到管线而到处乱挖乱掘等等。4.园林小品及园路施工在上述工作的同时,进行园林建筑及园路的施工。建筑小品种类繁多,材质各异。园路是园林的脉络,是联系各个风景点的纽带,是构成园景的重要因素,具有引导游览、组织交通、构成园景等等的作用。园路在结构上可分为面层、基层、垫层等三部分组成。此项工作在这里就不祥述了。5.种植定点放线种植放线必须遵循由整体到局部,先控制后局部,先乔木后灌木再到地被最后草地的原则。按图比例准确放线定点并作好标记(如乔灌木打木牌、地被及草撒石灰线),这是如何体现园林美的关键步骤。为了准确起见,可在种植点插上清晰的木牌,上面记载苗木品种、规格等。(1)对于规则式种植必须按设计图所要求尺寸、数量准确无误地在现场定好点,并作好标记。(2)对于自然式种植则在领会设计意图的前题下,力求准确地表现设计理念而进行灵活放线。除主景树需精确定点并标明外,其他次要同种树可用目测定点,放线一定要自然,切忌呆板、平直。草坪或地被植物边线要顺畅自然。(3)若受现场地物条件限制,可依实与甲方和质监单位商讨,在不影响景观效果的前提下或另选树种或稍微移位。6.挖穴整地这也是对定点放线的延伸,要符合设计和施工验收规范要求。(1)对于乔灌木,按设计的土球规格,以某省园林建筑雷竞技工程预算定额所定挖穴规格标准施工。值得注意的是必须使穴上口沿与底边垂直,大小一致,切忌挖成上大下小的锥形或锅底形。并按技术要求放置基肥,并在基肥上覆盖一层约15~20cm 的泥土,以防根系直接接触肥料而烧伤根系。(2)对于花灌类,松土层要达到50cm 以上。(3)对于草坪类(如台湾草),要求先压实土壤,再在上面铺一层(约3~5cm)优质嫩黄泥或细嫩沙壤土,然后用直木条等将土括平、括顺,并做好排水措施。7.植物准备植物准备也是一个关键环节,除了要严格按照设计及技术规范外,我们还要注意如下两点:(1)在确保低成本的前提下,必须计算好种植施工进度所需苗木的数量与种类,力求当天苗木当天完成种植。(2)树木形态要求:主要是要符合美观的实效作用,还要求与周围环境协调一致。8.种植种植最好在春秋两季,但由于工程需要往往要反季节施工,这就要求我们要采取适当的技术措施。种植一般按照大乔木中、小乔木灌木地被植物草皮 的顺序施工。(1)乔灌木种植。种植前先检查苗木状况进行适度修剪,剪去枯枝、烂枝、烂根、劈裂根、过长根,并进行疏剪、缩枝,以减少水分蒸发。但修剪时应注意树木形态,特别是孤植树。如果剪后(或锯后)大乔木伤口较大,在伤口上涂抹油漆,然后准确种植在预定位置,种植时注意观赏面,要种直,如果是规则式种植一定要行列对正。乔木灌木的栽植应注意前景与背景的关系,认真领会设计意图,充分展现植物的群体美与个体美。在丛植时,按要求应具有相同的胸径、冠幅,但它们姿态的丰满度及高度不完全一致,需要施工人员充分发挥自己艺术眼光,把植物进行因地制宜的调配组合,姿态丰满的处于主要观赏位置,前低后高,个体的姿态缺陷在组合位置上进行弥补,以达到最佳的植物景观效果。种后踩实、灌足水,使根系与泥土很好地粘在一起,不要出现有空隙,并用木棒等支撑好植株,支撑无论用何种方法都要一致以求实用美观。支撑选料应统一,粗细均匀、长度一致,绑扎时做到支撑物横平竖直,角度相同,并在树干处加上垫层来保护树皮免受损伤。如果是秋冬季节,可在大乔木上扎草绳以利保湿。如果是盛夏季节,还要考虑在大树上方搭遮荫网,遮荫网要离树冠50cm 以上,以利通风;如果树木特别高大,地面难于把水喷到树冠时,可引一条水管到树冠,并在水管上围绕树冠安置多个微喷头(待树木成活后再拆除)。(2)地被植物种植。按照株行距要求种植,种植边线清楚顺畅(特别是色块种植)。有些花苗叶较多、叶片较大(如美人蕉),也要进行适当修剪,以提高成活力。(3)草坪种植。我们一般是采取直接铺草块的形式种植草坪,铺完后浇足水,待半干后打实,使草与土壤充分接触,每天拍打一次,连续拍打三天以上,同时拍打要使草地平整。9.场地清理种植完成后,应立即清理施工现场如枝叶、绳索等垃圾。园林建筑及园路完成后,须立即清理如石材、木材、钢材、玻璃等废料,清洗水泥沙浆等残留物。有些还要进行适当补苗。只要我们用心做好雷竞技施工的每一步骤,严格把好质量关,便能创造出高质量的园林作品,供人们鉴赏,提高我们的生活质量。园林,雷竞技施工,雷竞技新闻中心aoutmy原创2016-05-04

最常使用于城市园林绿化中http://www.yjlvhua.com/news/540.htm绿篱又称植篱、生篱。常见的绿篱形式分为规则式和自然式两类。规则式绿篱是按照人们的需要,通过不断地修剪形绿篱又称植篱、生篱。常见的绿篱形式分为规则式和自然式两类。规则式绿篱是按照人们的需要,通过不断地修剪形成各种规则的、整齐的、艺术性的绿色墙垣。自然式绿篱外形自然。依绿篱的高度不同,可分为矮绿篱,高度控制在0.5 m左右;中绿篱,高度约lm;高绿篱,高度达2一3m以上。构成绿篱的植物不同,则名称也随之改变,如用开花的花灌木(桅子花、米兰、七姐妹蔫薇等)作植篱,称为花篱;如用带刺的植物,如小粟、火棘、黄刺玫等作植篱,则称之为刺篱;作为防护性绿篱,还有用桧柏等作绿篱达到分隔景区的目的;此外还在园林绿地中的“色带”与绿篱近似,也可以按规则绿篱来修剪。  (l)绿篱的培育  矮篱培育要从最小植株开始。要选那些又矮又粗的植株,不选又高又细的植株,一般株距5一13cm通常是大叶子的灌木比小叶子灌木种植密度要小些。栽植后的前一、二年的首要任务是增加植株的宽度。如果植株基部没有长出足够的枝条,在栽种时或生长季的前几周,要根据设计的绿篱高度来修剪(有的矮篱在离地15一30cm处短截),为了促进绿篱下部枝条生长,从水平方向发出的新枝不要剪掉太多。植株下部的枝条不能疏除,如果剪掉这些下部枝条会从修剪处形成直立枝,将在树篱的下端留下缺口,形成“光腿”现象。  随着绿篱在前三年中的生长,当新生长的直立枝比上一次修剪时的高度又长了15一30cm时,应剪掉其长度的1/2。同样,下部的枝条,一般不要剪去,随着植株下部的填满,变得比顶部更宽(图11-22)。  对于高篱,要防止下部枝叶干枯脱落。高篱种植后必须将顶部剪平,同时再将侧枝一律剪短,大大缩短营养的运输距离,也增强了各枝顶端对上行营养液的拉力,有利于养分向全树各部均匀分配,从而增加芽的萌发力,克服枝条下部“光腿”现象。每年在生长季均修剪一次,直至达到高篱要求为止。  (2)绿篱的维护  自然式绿篱的修剪可在任何时候进行,但在北方地区常绿阔叶绿篱的秋季修剪不得晚于“白露”之前,否则剪后萌发的新梢容易产生冻害。一般在春天新的生长开始前进行,剪后的空隙会很快被填满。自然式绿篱的维护通过回缩,或仅对最长的枝条进行短截,在绿篱外缘向内的15 -45cm短截,较短的枝条完整保留了下来,修剪后的绿篱外缘自然,对绿篱进行整形,使下部比上部宽,以便有足够的阳光照到下部的叶子上。  规则式绿篱的修剪,通常在生长季新枝开始变绿时进行。如果新长出的枝条不是太长、太乱,可等到植株生长变慢的时候再进行修剪。规则式绿篱的外形是几何图案,要利用人工或电动工具定期修剪(打头)维持形状,务必使下部比上部宽,以便有足够的阳光照到所有的叶子上。规则式绿篱正确的修剪方法,应先剪其两侧,使其侧面成一个斜面,两侧剪完,再剪平顶部,整个断面呈梯形。这样修剪,可使绿篱植株上、下各部枝条的顶端优势受损,刺激枝条再长新侧枝,而这些侧枝的位置,距离主干相对变近,有利于获得充足养分。同时,上小下大的斜面,有利于绿篱下部枝条获得充分阳光,从而使全树枝叶茂盛,维持美观外形。如果对绿篱两侧面的修剪强度完全一致,其断面形成上下垂直的长方形(图11-23),那么下部枝叶因处于树荫下,阳光不充足而逐渐发黄枯死脱落,最终造成下部光秃裸露。  对建成的规则式绿篱打头时,最后的打头长度应在2一3cm。为不使绿篱生长过高、过宽,每一两年可以选择修剪至前一季节的生长量。最好在春天修剪,那时新的生长即将开始,植株仅光秃很短一段时间。  当前园林实践中,许多地方修剪绿篱时,只将顶部剪平,很少或根本不剪两侧枝条,这样,下部的侧枝终年得不到阳光,也没有外来刺激,逐渐干枯死亡,形成基部光秃。从断面看,形成上大下小的倒梯形,景观效果很差。  花篱大都采用自然式,最好在花谢后进行修剪,这样既可防止大量结实和新梢徒长,又能促进花芽分化,为来年或下次开花作准备。但平时要做常规疏剪工作,将枯死枝、病虫枝、伸展过长过远扰乱树形的枝条全部剪除。苗木求购信息  (3)绿篱的更新  大多数绿篱最终都将变得过大。对阔叶树绿篱的修复,在春天新梢生长开始之前,大约回缩到绿篱体量的一半大小。这种方法将显露出无叶或少叶的新枝。务必使较低处的枝条比顶部的枝条长,以便所有新叶接受到阳光。当新枝长到10cm长,然后再进行常规修剪,重整绿篱。对自然式绿篱修剪时,剪后的枝条要长短不齐,以保持开展自然的外形。对针叶树篱进行修剪时,要避免重剪,否则,大多数难以成活。苗木,绿篱类苗木新闻中心不详原创2016-04-28

 (一) 土壤的选择和处理  要选择通气、透水性好,有保水保肥能力,土内水、肥、气、热状况协调的土壤。经多年实践,用泥沙拌黄土(3:1为佳)作为移栽后的定植用土比较好,它有三大好处,一是与树根有"亲和力"。在栽培大树时,根部与土往往有无法压实的空隙,经雨水的侵蚀,泥沙拌黄土易与树根贴实;二是通气性好。能增高地温,促进根系的萌芽,三是排水性能好。雨季能迅速排掉多余的积水。免遭水沤,造成根部死亡,旱季浇水能迅速吸收、扩散。  在挖掘过程中要有选择的保留一部分树根际原土,以利于树木萌根。同时必须在树木移栽半个月前对穴土进行杀菌、除虫处理,用50%托布津或50%多菌灵粉剂拌土杀菌,用50%面威颗粒剂拌土杀虫(以上药剂拌土的比例为0.1%)。  (二) 移栽后的水、肥管理  1、 旱季的管理:6~9月,大部分时间气温在28℃以上,且湿度小,是最难管理的时期。如管理不当造成根干缺水、树皮龟裂,会导致树木死亡。这时的管理要特别注意:一是遮阳防晒,可以树冠外围东西方向"几"字型,盖遮阳网,这样能较好的挡住太阳的直射光,使树叶免遭灼伤;二是根部灌水,信预埋的塑料管或竹筒内灌水,此方法可避免浇"半截水",能一次浇透,平常能使土壤见干见湿,也可往树冠外的洞穴灌水,增加树木周围土壤的湿度;三是树南面架设三角支架,安装一个高了树1米的喷灌装置 ,尽量调成雾状水,因为夏、秋季大多吹南风,安装在南面可经常给树冠喷水,使树干树叶保持湿润,也增加了树周围的湿度,并降低了温度,减少了树木体内有限水分、养分的消耗。没条件时可采"滴灌法",即在树旁搭一个三角架,上面吊一只储水桶,在桶下部打若干孔,用硅胶将塑料管粘在孔上,另一端用火烧后封死,将管螺旋状绕在树干和树枝上,按需要从没方向在管上打孔至滴水,同样可起到湿润树干树枝、减少水分养分消耗的作用。  2、 雨季的管理:南方春季雨水多,空气温度大,这时主要应抗涝。由于树木初生芽叶,根部伤口未愈合,往往会成树木死亡。雨季用潜水泵逐个抽干穴内水,避免树木被水浸泡。  3、 寒冷季节的管理:要加强抗寒、保暖措施。一要用草绳绕干,包裹保暖,这样能有效地低御低温和寒风的侵害,二是搭建简易的塑料薄膜温室,提高树木的温、湿度,三是选择一天中温度相对较高的中午浇水或叶面喷水。  4、 移栽后的施肥:由于树木损伤大,第一年不能施肥,第二年根据树的生长情况施农家肥或叶面喷肥。  (三) 移栽后病虫害的防治  树木通过锯截、移栽,伤口多,萌芽的树叶嫩,树体的抵抗力弱,容易遭受病害、虫害,如不注意防范,造成虫灾或树木染病后可能会迅速死亡,所以要加强预防。可用多菌灵或托布津、敌杀死等农药混合喷施。分4月、7月、9月三个阶段,每个阶段连续喷本次药,每星期一次,正常情况下可达到防治的目的。  大树移栽后,一定要加强养护管理。俗话说得好,"三分钟,七分管",由此可见,养护管理环节在雷竞技建设中的重要性。当然,要切实提高大树移栽后的成活率,还要在绿地规划设计、树种选择等方面动动脑筋,下点功夫。园林,大树移栽新闻中心不详原创2016-04-15 13:46绿化苗木 最常使用于城市园林绿化中http://www.yjlvhua.com/news/537.htm苗木种植是雷竞技工程中一项必不可少的施工工序。苗木种植费用的计算是根据施工设计图上苗木的数量乘以相对应的定额种植苗木种植是雷竞技工程中一项必不可少的施工工序。苗木种植费用的计算是根据施工设计图上苗木的数量乘以相对应的定额种植费用基价,计算出该品种苗木的复价,复价累计之和即为该工程的定额种植费用。  定额种植费用的基价,是根据苗木的各种内在质量规格指标确定的。所谓苗木内在质量规格指标,不是通常所指的苗木高度、蓬径等外形尺寸,而是指苗木根部所带泥球大小、胸径大小、地径大小等尺寸指标,两者是有根本区别的。  根据“九三”园林定额规定,按照苗木分类不同,其苗木的内在质量规格指标也是不同的。通常在计算时,常绿乔木、灌木是以泥球大小;落叶乔木、竹类是以胸径大小;灌木、绿篱是以苗木高度;草坪是以铺种的不同方式;攀缘植物是以地径大小……等等不同标准,取定额种植费用的多少。  所以我们在计算苗木的质量规格标准是否齐全(一般有雷竞技设计资质的单位,均有能力也应该完成以上设计要求)。只有数量正确,质量规格指标齐全、才能正确套用定额规定的种植子目基价,保证其种植费用计算的正确性。  根据“九三”园林定额规定,计算出的工程苗木种植费用,除古树木的种植、移植、保护费用可由双方协商确定外,一般种植费用中,均应包括苗木种植、竣工移交后一个月的养护工作(单纯花坛种植为10天)。工程苗木成活率为100%,竣工移交后,若有死亡苗木,应由施工单位补种齐全后,方可正式移交给甲方(业主),由甲方(业主)进行后期的雷竞技养护日常管理工作。苗木,雷竞技工程,雷竞技新闻中心不详原创2016-04-13

首先,花叶类园艺品种大多需全光照条件,否则长势不良,且花叶性状将逐步丧失。而在目前普遍夏季高温干旱的城市绿地,越夏浇水管理相对困难,因此一些叶形较大、叶片较薄质的花叶种,其蒸腾作用强、失水快,容易引起叶枯焦,即便在林缘、疏林下配置也可能引起灼烧现象,如花叶玉簪、花叶锦带花、花叶节骨木等。  其次,在夏季高温多雨的江南地区,尤其是梅雨季节,植株往往生长表现不理想,环境过湿易引起腐烂,叶枯、叶烂后的群体景观效果不佳,如金叶过路黄、多花筋骨草、银香菊、绵毛水苏等。此外,尽管某些彩叶类地被植物在局部地区配置形成了良好的景观效果,但不适于大面积栽植,如花叶杞柳、紫叶酢浆草、花叶美国薄荷等。  彩叶类地被植物能形成炫耀亮丽的植物景观效果,但如应用过多,则难免过于花哨,容易引起视觉疲劳。随着人们雷竞技观念的回归,今后将更为注重自然的绿色,因此应慎重选择彩叶植物,尤其在大面积进行的园林地被应用中。  对于地被植物彩化、亮化的发展趋势,我们提倡应大量应用观花类地被植物,如宿根美女樱、宿根天人菊、美丽月见草、常夏石竹、地稔、二月兰、蝴蝶花、马蔺、白芨、中华蟛蜞菊、旋覆花、岩白菜、蛇莓等。要充分考虑植物种类和品种的生态习性、生长适应性和观赏价值特点,以期达到最佳的景观效果。地被植物新闻中心不详原创2016-03-25 11:38
