坠枝和拉枝都是用来开张果树枝条角度,达到缓和树势。促进花芽分化和早果早丰目的的。但在生产运用上,坠枝不如拉枝效果好。这是因为:(1)坠枝的角度不易拉制,其角度会随着枝条持续下垂而不断开张,结果是或角度不开张,或开张过了头。(2)坠枝因其下垂下限,为了达到开张角度,往往会使被坠枝成弓型,容易冒条。(3)坠枝时间不易掌握,且只能开张角度,不能改变被坠枝
Falling branches and pulling branches are used to open branches of fruit trees point of view, to ease the tree vigor. Promote flower bud differentiation and early fruiting purposes. However, in the production and use, not as good as pulling branches. This is because: (1) the angle of falling branches is not easy to draw, and its angle will continue to open as the branches continue to sag, with the result that the angle is not open, or opened too far. (2) falling branches due to its lower limit of sagging, in order to achieve the opening angle, tend to make the bow into a bow, easy to take the bar. (3) fall time is not easy to grasp, and can only open the point of view, can not be changed by falling branches
