苹果在生长期,果树体消耗了大量的养分。因此,苹果树必须在果实采收后及时进行施肥。此期施肥,不仅补充树体急需营养,而且,直接关系到下一年的产量。采果后,最好施基肥,因为秋季施基肥能有充分的时间腐熟和供果树在休眠前吸收和利用、加强光合作用,增强贮藏营养物质,同时,这时正值根系生长高峰,伤根容易愈合,并能促进生长新根;还能促进后期叶功能,增加光合产物的积累,为树体储备更多的营养,也有利于枝条、芽体的充实和晚化芽的形成。施基肥的种类以腐熟的农家有机肥为主,也可适当配施少量的氮素化肥。施基肥的方法
The apple tree consumes a lot of nutrients in the growing season. Therefore, the apple tree must be timely fertilized after the fruit is harvested. This period of fertilization, not only to supplement the urgent need for nutrition tree, but also directly related to the next year’s production. After picking the fruit, the best base fertilizer, because the base fertilizer in autumn can have sufficient time for decomposing and fruit trees for absorption and utilization before dormancy, enhance photosynthesis, enhance storage of nutrients, at a time when the root growth peak, root injury Easy to heal, and can promote the growth of new roots; but also to promote late leaf function, increase the accumulation of photosynthetic products, reserve more nutrients for the tree, but also conducive to the branches, buds enrichment and late bud formation. The type of basal fertilizer to decompose the main farm organic fertilizer, but also can be appropriate with a small amount of nitrogen fertilizer. The method of base fertilizer
