(1) 氮肥催春梢 茶花一般在18℃左右开始荫发春梢。这时要施氮肥为主的摧芽肥,每10天1次,直到春梢开始木质化为止。有条件的,还可同时用磷酸二氢钾1000倍、1%左右的尿素和300倍左右的米醋混合稀液进行叶面喷施。经过多次根部和叶面喷洒,春梢就会长得十分茂盛,叶片能伸展到最大限度,枝梢能积累丰富的营养物质,为花芽分化创造良好的条件。 (2)增施磷、钾肥,促使花芽分化,形成花蕾 茶花春梢抽足,进入木质化后,会有一段较短的半休眠期。这时茶花由营养生长阶段转入生殖生长,花芽开始分化。如果要使茶花多结蕾,应多施磷、钾肥,不施或少施氮肥。如果小株茶花以发棵为主,则仍以氮肥为主,不施或少施磷肥。每10天左右用1000倍磷酸二氢钾、少量硼砂和米醋混合稀液进行叶面喷施,既可以控制茶花枝条徒长,又能促进和缩短花芽分化时间,利于花蕾形成。 (3) 盛夏不宜施肥,更不能施浓肥 盛夏天气炎热,茶花生长缓慢或陷于半停顿状态。此时不宜施肥,特别要注意不能施浓肥。如土质瘠薄,可结合浇水略施稀薄的液肥,以改善土质。 (4)秋季适当施以磷、钾肥为主的混合肥 秋季天高气爽,属茶花植株营养积累期。为了安全越冬,每隔半个月可施以磷、钾肥为主的混合肥,结合叶面喷施,促进植株健壮,提高茶花抗寒力。 (5)冬天宜施稀磷钾液肥 寒冬的茶花进入半休眠期。茶花入室入窖,营养生长已进入休眠,不需多少肥料。但它生殖生长并未完全停止,正处于开花或准备开花的季节,应结合浇水施稀薄的磷钾液肥。切忌施浓肥。 (1) the growth of spring Camellia at the beginning of 18 days is usually caused by nitrogen fertilizer. At this time, nitrogen fertilizer should be used as the main fertilizer to remove buds, 1 times every 10 days until the sprouts begin to lignification. Conditional spraying of potassium dihydrogen phosphate 1000 times, about 1% urea and about 300 times of rice vinegar mixed with dilute solution can also be applied. After a number of roots and foliage spraying, the spring shoots will grow very luxuriantly, and the leaves can extend to the maximum. The branches can accumulate rich nutrients and create good conditions for the differentiation of flower buds. (2) increase phosphorus and potassium fertilizer, promote flower bud differentiation, form flower bud camellia flower spring shoot foot, and after entering lignification, there will be a short half dormancy period. At this time, Camellia turned from vegetative stage to reproductive growth, and flower buds began to differentiate. If we want to make the camellia more bud, we should use more phosphorus and potassium fertilizer, and do not apply or apply less nitrogen fertilizer. If the small plant Camellia is mainly planted, it is still mainly nitrogenous fertilizer and no or less application of phosphate fertilizer. The foliage spraying with 1000 times potassium dihydrogen phosphate, a small amount of borax and rice vinegar every 10 days, can not only control the growth of the flower branches of the tea flower, but also promote and shorten the time of flower bud differentiation, which is beneficial to the bud formation. (3) it is not suitable to fertilize in midsummer, but not to fertilize in midsummer. The weather is hot in midsummer, and the growth of camellia is slow or half halted. It is not suitable to fertilize at this time. If the soil is barren, the thin liquid fertilizer can be combined with watering to improve the soil quality. (4) in the autumn, Shi Yilin and potash fertilizer were the main nutrients in autumn, which belonged to the vegetative accumulation period of Camellia plants. In order to survive the winter safely, Shi Yilin and potash fertilizer should be used every half a month to combine the foliar spray to promote the plant's sturdy and enhance the cold resistance of Camellia. (5) in winter, the Camellia in cold winter is suitable for the semi dormancy period. When the camellia enters the cellar, the vegetative growth has entered into dormancy without much fertilizer. But its reproductive growth has not stopped completely. It is in the season of flowering or ready to bloom. Do not apply strong fertilizer.
