修剪能促进苹果树生长,延长寿命,提高果品产量和质量,但要合理修剪,否则,是达不到这个目的。在过去一个时期,我们曾机械地仿造基部三大主枝邻近的树形,大拉大砍,强做树形,结果大枝上的隐芽大量萌发,满树冒条,树冠老化而伸展缓慢。后来又采取了无计划的“轻剪长放”,结果又形成枝条过密过长,树冠郁闭,通风透光不良,内膛小枝大 Pruning can promote apple tree growth, prolong life and improve fruit yield and quality, but to be properly pruned, otherwise, is not up to this purpose. In the past period, we have mechanically imitated the tree shapes adjacent to the three main branches of the base, raged large and made tree shapes. As a result, the hidden buds on the large branches germinated extensively, the trees ran thick, and the canopy stretched slowly. Later, they took a unplanned “light cut long”, the result is too long branches formed too crowned canopy, ventilation and poor light, the inner branch sprig large
