一看树形。培养和调整树形是苹果冬剪的一项主要任务。不同的栽培方式(乔化、半矮化、矮化等),不同的栽植密度要选择不同的树形。乔化密植亩栽33～55株的宜选择简化小冠疏层形,矮化密植亩栽66～83株的宜选自由纺锤形,矮化密植亩83～111株的宜选细长纺锤形。如果疏于管理,树形紊乱,那就需要进行树形改造,冬剪就要重一些,修剪量较大一些。如果树形比较规范,没有完成树形培养目标的继续进行树形培养;树形完成的按规范要求进行适当调整。这样的话,冬
A look at the tree. Cultivating and adjusting the tree shape is one of the main tasks of Apple’s winter scissors. Different cultivation methods (Qiao, semi-dwarf, dwarf, etc.), different planting density to choose a different tree. Qiaohua dense planting planted acres of 33 to 55 should choose to simplify the sparse small sparse crown, dwarf dense planting acres of 66 to 83 plants should be selected from the spindle, dwarf densely planted acres of 83 to 111 strains should be selected slender spindle . If you neglect management, tree disorder, it needs to be tree-shaped, winter cut will have to be heavier, a larger amount of pruning. If the tree is more normative, do not complete the tree training objectives continue to tree training; tree completed according to the specifications required to make appropriate adjustments. In this case, winter
