苹果幼树期间一般发枝少,要想早成形、早结果,必须使幼树尽快增加枝量,而且要在预想的部位有枝,但生产实践往往是要枝的地方没有枝,造成偏树;要枝组的地方无枝形成枝组,造成光腿,特别是离剪口远的地方,很难发枝,这给幼树整形、早期丰产带来很大困难。为了解决幼树枝量不足的问题,我们应 In general, young shoots tend to grow less during apple saplings. In order to prematurely shape and early results, young shoots must be increased in quantity as soon as possible and branches must be planted at the desired locations. However, branches are often not practiced in production practice, resulting in partial trees ; Zhizhi group of branches without the formation of branch group, resulting in bare legs, especially away from the scissors far, it is difficult to shoot, which give young trees plastic, early bumper crop brought great difficulties. In order to solve the problem of insufficient seedlings, we should
