1.对大枝的处理在疏除上下功夫。首先疏除着生在中央干上过大、过密、下部光秃、影响通风透光的大枝,以增加有效叶面积,提高光能利用率。在本着疏一有利左右而助全树的同时,还要注意整个树势,维持上下平衡和树冠内的生长结果能力。完成2～3层主枝,并在树势稳定后,及时落头开心,控制树冠高度,一次将中干的顶部去掉,落头处的侧枝和大型辅养枝短截或轻剪长放。2.对小枝和花芽的修剪,细抓一个“疏”字。疏剪骨干枝前端外围这密枝,减少外围枝量,增加内膛枝的生长结果能力。疏剪多花中庸树花芽总量的40％左右,疏剪多花弱树花芽总量的60％左右,对中、长 1. The treatment of large branches in the sparse effort. First of all, we should sparse the large branches that live in the central government and are too big and too dense. The lower branches are bare and affect the ventilation and light. In order to increase the effective leaf area and increase the utilization rate of light energy, In the sparse and beneficial around the help of the whole tree at the same time, but also pay attention to the entire tree vigor, to maintain the balance between the upper and lower crown and the ability to grow results. Complete 2 to 3 layers of main branch, and in the stable of the tree, in time to fall happy, control the height of the canopy, one at the top to remove the stem, the beginning of the branch and the large branch of the secondary repair cut or cut light and long. 2. Pruning branchlets and flower buds, fine grasping a “sparse” word. Dredging the bony branches around the front of the dense branches, reducing the amount of peripheral branches, increasing the capacity of the growth of the billet branch. Sparsely cut flowers spend about 40% of the total amount of moderate tree sprouts, sparsely cut more spend about 60% of the total amount of weak tree flowers, the medium and long
