一、秋季施肥灌水对于土肥水管理较差的果园,特别是一些土壤瘠薄的果园,要搞好秋冬季施肥,施肥时间一般是果实采收后到落叶前进行。此时正是果树根系二次或三次生长高峰,苹果树主要根系分布层的土温较高,有利于微生物活动,根系生长旺盛,吸收机能活跃,有利于树体吸收,还可补充果实采收后的树体营养,恢复树势。常用的基肥主要有猪粪、人粪尿等各种厩肥及少量氮索化肥。粪肥要先堆沤腐熟后再用。1.施肥方法可采用放射状沟、环状沟、行间深沟或全面措施等多种方法。一般采用环状沟 First, the fall of fertilizer irrigation Fertilizer and water for poor management of orchards, especially some barren orchards, to do a good job autumn and winter fertilization, fertilization time is generally harvested after the fruit leaves before deciduous. At this moment, it is the secondary or tertiary growth peak of the root of the fruit tree.

The root system grows vigorously and absorbs the active energy, which is good for the tree body to absorb, After the tree nutrition, restore the tree vigor. Commonly used base fertilizer mainly pig manure, human waste and other manure and a small amount of nitrogen fertilizer. Manure must be piled up before use. 1. Fertilization methods can be radial ditch, annular ditch, inter-line deep trench or comprehensive measures and other methods. Generally use annular groove
