苹果树在良好的土肥水等综合管理基础上,合理进行整形修剪是调节果树生长发育的重要途径之一。但近年来,由于各地留枝密度不一,表现在修剪程度上,走向忽轻忽重两个极端,在修剪方法上片面强调某一个方法是唯一的,因此在生产中一些果树表现光照不足、内膛枝细弱,结果部位外移,达不到立体结果,造成“大小年”结果严重,果品质量下降。针对我省存在的苹果树留枝密度不合理的主要矛盾和当前树的生长发育特点,提出以下几点意见,供各地参考。
Apple trees in a good soil fertility and other integrated management based on the rational pruning is to regulate the growth and development of fruit trees one of the important ways. However, in recent years, due to the density of stay branches everywhere, the performance of the degree of pruning, to the neglect of the two extremes, one-sided emphasis on pruning a method is unique, so in the production of some fruit trees show insufficient illumination, within Fibrous limbs, the results of part of the relocation, not up to the three-dimensional results, resulting in “size year” results are serious, declining fruit quality. In view of the main contradictions of irrational remaining branch density of apple trees existing in our province and the current growth and development characteristics of trees, the following opinions are put forward for reference.
