一、确定树形及主侧技1.确定树形可根据栽植密度选定适宜的树形,一般稀植树多采用疏层形,中度密植树(667米~240～60株)可采用小冠形,高密度(667米~280～120株)可采用圆柱形或塔形。目前各地多采用中度植树栽培,以小冠疏层形(简称小冠形)为例。2.选定主枝小冠形树体由中央干及5～6主枝构成,主枝分上下两层,下层3～4个,上层2个,现有的大枝中选方位适合的3～4个枝子为主枝,主枝头要选在一年生强枝的饱芽上下剪,剪口芽留在
First, to determine the tree and the main skill 1. Determine the tree according to the planting density selected appropriate tree shape, generally sparsely layered sparse use of sparsely layered, moderately dense tree planting (667 m ~ 240 ~ 60) can be small Crown-shaped, high-density (667 meters ~ 280 ~ 120 strains) can be cylindrical or tower-shaped. At present, the use of moderate planting around more trees to sparse small crown shape (referred to as the small crown) as an example. 2. The selected main branch of the small crown-shaped tree from the central stem and 5 to 6 main branches, the main branch is divided into two layers, the lower 3 to 4, the upper 2, the existing large branches of the election for the appropriate orientation of 3 to 4 A branch of the main branch, the main branch to be elected in the annual branch of the full buds of the upper and lower shear, cut buds left
