果树冬季修剪是通过人为控制和调节树冠各部生长结果的一种技术手段,是冬季果园管理中技术含量最高的工作。修剪的好坏直接关系到第2年甚至以后的生产,合理修剪能起到事半功倍的效果。无论栽培技术怎么更新,冬剪的基本要素必须掌握以下五点:一是树形的选择要符合果树品种生长结果的特性。二是树形应有利于树冠的通风透光和立体结果。三是控制树高和树冠,其范围应根据不同的地理环境综合考虑,一般树高应控制在3米以下,树冠直径 Winter pruning of fruit trees is a technical means by which people control and adjust the growth results of the branches of the canopy. It is the most technologically advanced work in winter orchard management. Pruning is directly related to the second year or even after the production, reasonable pruning can play a multiplier effect. No matter how the cultivation technique is updated, the basic elements of winter shear must have the following five points: First, the choice of tree should be consistent with the characteristics of the fruit tree growth results. Second, the tree should be conducive to the ventilation of the canopy and three-dimensional results. Third, the control of tree height and crown, the scope should be based on different geographical considerations, the general tree height should be controlled at 3 meters below the crown diameter
