拉枝是用绳子、铁丝等将其某种着生状态的枝,拉到一定的开张角度和缺枝方位的措施。直立和角度小的枝被拉大角度后,能有效地削弱该枝的顶端优势,提高中下部芽的萌芽率,生成较多的枝量和中短枝,有利于形成较多的花芽;空间较小的枝,被拉向空间较大的缺枝方位,能丰满树冠,填充其空间,弥补其缺枝,克服偏冠现象,有利于提高形成树形。树冠长到一定高度,将中心和侧生的骨干枝、延长枝分别拉倒和拉向侧生,有利于控制树高和冠径等。总之,拉枝是使果树早结果、多结果的措施之一。苹果树拉枝的方法是: Pull the stick is a rope, wire and other will be a kind of living state of the branches, pulled to a certain degree of opening angle and the direction of the missing branches. When the erect and small angle branches are widened, the top edge of the branch can be effectively weakened, the germination rate of middle and bottom buds can be increased, and more branches and short branches can be formed, which helps to form more flower buds. Space Smaller branches are pulled to a larger space where they can fill the crown, fill their space, make up for their lack of branches, and overcome the phenomenon of partial crowns, which helps to improve the formation of trees. Canopy grow to a certain height, the center and the lateral branches of the backbone, the extension of the branches were pulled down and sideways, is conducive to the control of tree height and crown diameter. In short, pulling the stick is one of the early results of the fruit tree, the result of more than one. Apple tree pull branches are:
