近些年来,新发展梨园多为密植园。整形修剪如果按传统修剪方法进行,势必造成树冠过高,骨干枝数量多,枝条密集,通风透光不良,树势偏旺,结果晚,形成花芽少,座果率低等不良现象。通过对几个果园连续几年改革整形修剪方法,保持树体了骨干枝级次少,开张角度好,结果枝组在冠内外、上下分布均匀,无结果部位外移现象。果园 In recent years, the newly developed pear orchard is mostly a densely populated garden. Trimming if the traditional method of pruning, is bound to cause the crown is too high, the number of backbone branches, branches dense, poor ventilation and ventilation, tree vigor Wang, the result is late, the formation of flower buds less, fruit set rate is low and other undesirable phenomena.
