树冠是由许多不同年龄枝条组成的,在不同年龄的枝条上,具有正常芽和休眠芽。大多数正常芽着生在一年生枝条上,休眠芽隐藏在多年生枝和更老的树干内。因为芽的性质和着生部位不同,每个芽所萌发出来的枝条,都有其相对的独立特性,特别明显的是生长与结果的特性不同。在苹果幼树整形中,要着重掌握芽和枝条生长的特性,就能够预料到修剪后的反应效果。
Crown is composed of many branches of different ages, branches of different ages, with normal buds and dormant buds. Most normal buds live on annual branches, and dormant buds hide in perennial branches and older tree trunks. Because of the nature of buds and the different parts of their births, the shoots that emerge from each bud have their own relative independence, most notably the different characteristics of growth and outcome. In apple tree plastic surgery, we should focus on grasping the growth characteristics of buds and branches, we can expect to prune the response.
