幼龄苹果树的冬季修剪,主要是采用增枝、促花手法的同时,注意树冠的通透性,使骨干枝迅速生长成形,辅养枝及时成花结果。 一、增枝扩叶,这是幼树从营养生长转化为生殖生长的重要物质基础。 轻剪缓放,多留少疏:在服从整形要求基础上,以轻为主。轻重结合。一方面要重视早果早丰,另一方面要重视骨架的建设和后期丰产。对骨干枝延长枝头应适当短截,对竞争枝、过密枝、病虫枝可进行疏除,其余枝条均宜轻剪缓放或变向。 培养枝组:为了缩短苹果幼年期,实现早期丰产,要特别注意培养细长型和单轴型枝组及斜生、下
Winter pruning of young apple trees, mainly by the increase of branches, flowers and flowers at the same time, pay attention to the permeability of the crown, so that the rapid growth of the backbone of the formation of branches, branch branches in time into flowers results. First, the expansion of branches and leaves, which is young trees from vegetative growth into an important material basis for reproductive growth. Gently slow release, stay less sparse: in compliance with plastic requirements, based on light-based. Combination of light and heavy. On the one hand, we must pay attention to early fruiting and early abundance, on the other hand, we must attach importance to the construction of the skeleton and the late harvest. On the backbone of branches to extend the branches should be appropriate short cut, the competition branches, dense branches, branches and pests can be sparse, the rest of the branches should be gently cut or change. Cultivation of branches: In order to shorten the juvenile apple, to achieve early harvest, pay special attention to cultivate slender and uniaxial branches and oblique, under
