1、主枝开角:短枝型苹果树第一层主枝角度一般要求60—70度,而幼旺树主枝角度都偏小,可在5月份采用撑、拉、别等方法开张角度。开角可明显改善树冠内膛通风透光条件,缓和枝梢生长,均衡树势,有利于扩大树冠及花芽分化,提早结果。
1, the main branch opening angle: spur-type apple tree The first branch of the main branch of the general requirements of 60-70 degrees angle, and the branches of the tree branches are too small, can be used in May, pull, pull, and other methods of opening angle . Open angle can significantly improve the canopy ventilation and light conditions, to ease the growth of shoots, balanced tree potential, is conducive to expanding the canopy and flower bud differentiation, early results.
