试验表明:苹果树冬剪的时间不同,效果也不一样。如严寒以后,春季树液流动前修剪的苹果树,第二年的生长势比较旺盛,结果良好,产量也较高;同时,对低温和干旱等不良外界环境条件的抵抗力也强。据观察在这段时间内修剪越早,越有利于促进树体生长,修剪时间越晚,作用就越小。因此,为使苹果幼树树冠迅速扩大,增加枝叶量,减轻生理干旱和灾害,应在11—12月间完成修剪。
Tests show that: apple tree winter shear time is different, the effect is not the same. For example, after cold, the apple tree pruning before the flow of sapwood in spring increased vigorously in the second year with good result and high yield. Meanwhile, it also possessed strong resistance to adverse external environmental conditions such as low temperature and drought. It is observed that during this period of pruning earlier, the more conducive to promoting the growth of trees, pruning time later, the smaller the role. Therefore, in order to make apple tree canopy rapidly expand, increase the amount of branches and leaves, reduce physiological drought and disasters, should be completed in 11-12 months pruning.
