一、整形修剪中的问题我省中南部是苹果新区,在整形修剪上走了不少弯路。六十年代强调树形,修剪过重,七十年代推广“多留长放”,造成树形紊乱,树冠郁闭,树势衰弱,结果部位外移,果品产量、质量下降。主要表现是:1.树体过高。15—20年生大树一般树高均在5米以上。有的主枝角度小,抱头生长,帽子大,造成严重遮阴。 First, the problem of plastic trim In central and southern parts of our province is Apple’s new area, go in a lot of detours on the plastic trim. In the 1960s, emphasis was placed on the tree shape and over trimming. In the 1970s, the promotion of “leaving more and more long” resulted in derangement of the tree, closed canopy, weakening of trees and relocation of the resulting parts. The output and quality of fruit products declined. The main performance is: 1. The tree is too high. 15-20 year-old trees are generally 5 meters above the tree height. Some main branches angle is small, Baotou growth, hat big, causing serious shade.
