苹果树的枝势、枝量和负载量三者之间有着密切的生物学关系。为保持高产、稳产和树势健壮、长寿,必须经常调整三者之间的平衡。 枝势 枝势的强弱常用来表示苹果树的生长势。调控枝势除运用肥水条件外,主要通过控制修剪量来实现。比如: 1.为增加枝势,可加大修剪量,用助势修剪法;为削弱枝势,可用减少修剪量,用缓势修剪法。 2.幼树期为达到快长树迅速扩大树冠,修剪时对各级骨干枝的延长
Apple tree branches, branches and the amount of load between the three have a close biological relationship. In order to maintain high yield, stable yield and robust tree growth, longevity, we must always adjust the balance between the three. The strength of branches and branches is often used to indicate the growth potential of apple trees. In addition to the use of regulation and control of water and fertilizer conditions, mainly through the control of the amount of pruning to achieve. For example: 1. To increase the branch, you can increase the amount of pruning, with the potential pruning method; to weaken the branches, available to reduce the amount of pruning, with ease pruning method. 2. Saplings to achieve rapid growth of trees quickly grow crown, pruning at all levels of the backbone of the extension
