一、放任树的修剪。放任树是指没有修剪基础,让其自然生长的树。对放任树的修剪原则是:因树修剪,随枝造形,不能操之过急,切忌大杀大砍。修剪时首先应张开角度,选出几个方位、部位较好的大枝作主枝和侧枝。对多余的大枝可分2~3年逐步回缩疏除。有空间的大枝,可适当回缩,去弱留强,改造成大型枝组。对中心干上过密的辅养枝,去小留大,打开层次。同时,应注意利用骨干枝光秃部位的营养枝培养结果枝组,以填补空间。
First, leave the tree pruning. Indulgent trees are trees that are not pruned to grow naturally. The principle of pruning a lazy tree is: pruning the tree, with the stick shape, can not be hurried, should not kill. Pruning should be the first to open the angle, select a few azimuths, the better part of the main branch and side branches. The extra large branches can be divided into 2 to 3 years gradually shrink thinning. There is room for large branches, may be appropriate retraction, weak to stay strong, transformed into large branches group. On the center of stems too close to supporting the branch, to stay small, open level. At the same time, should pay attention to the use of bare branches of the backbone of the vegetative shoots branch group training to fill the space.
