1 拉枝时间及效果 苹果幼旺树枝以秋季(8月中旬至9月下旬)效果最佳。拉枝抑制秋梢生长。有利于均衡树势,扩大树冠;秋季树枝柔软,可塑性强,有利于改善树体光照,控制新梢旺长,促进中下部芽体充实,提高翌春芽率。秋季拉枝后改变了枝的生长方向,使养分向芽内流动,有利于芽体充实,提高成花率。2 拉枝角度 一般要求侧枝70～80度
1 Pulling time and effect Apple vigorous branches in autumn (mid August to late September) the best. Pull the branches to inhibit the growth of autumn shoots. It helps to balance the tree vigor and enlarge the canopy. In autumn, the branches are soft and strong in plasticity, which helps to improve the light of the trees, control the growth of new shoots, promote the enrichment of the buds in the middle and lower parts, and improve the rate of the next spring buds. Pull branches after the autumn changed the growth direction of the branches, so that nutrients flow to the bud, is conducive to enrich the buds and improve the flowering rate. 2 pull branch angle generally require collateral 70 to 80 degrees
