樱桃树生长迅速,发育阶段性明显而且集中。中国樱桃从开花到果实成熟采收,不过50天左右。大樱桃约需60天。树叶的生长和开花结果都集中在生长季节的前半期,花芽分化多在采果后的短时间内完成。因此,必须根据樱桃的特点合理施肥。在施肥过程中要把好三关,即早施基肥、花期追肥和采果后补肥。在肥料种类上,有机肥要多,磷钾肥比例要大,氮肥的用量宜少。 一、早施基肥 以秋季早施为宜,一般不得晚于11月。圈肥、土杂肥、人畜粪便均可。幼树和初果期树株施人畜粪尿30-60公斤或圈肥
Cherry trees grow rapidly, the stage of development is clear and concentrated. Chinese cherry harvest from the flowering to ripe fruit, but about 50 days. Cherry takes about 60 days. Leaf growth and flowering results are concentrated in the first half of the growing season, flower bud differentiation more in the short time after picking fruit. Therefore, we must rationalize the fertilizer according to the characteristics of cherry. In the process of fertilization should be a good three off, that is, early base fertilizer, topdressing flowers and plucking fruit. In the type of fertilizer, organic fertilizer to be more, a greater proportion of phosphorus and potassium fertilizer, nitrogen fertilizer should be less. First, early application of base fertilizer to fall as soon as possible, usually no later than November. Circle fat, Tuza Fei, man and animal manure can be. Saplings and early fruiting period of tree manure excrement urine 30-60 kg or lap fertilizer
