苹果由于短枝型品种和普通型品种的生物学特性有很大差异,因此在修剪上也有所不同。 一、幼树期修剪。短枝型品种以促为主,普通型以缓为主。短枝型品种树体矮小,节间短,萌芽率高,但成枝力弱,一旦形成短枝,进入结果期树冠扩大就极缓慢,不易成形。因此幼树期修剪应以促为主,使枝条放任生长,尽量多发枝,发旺枝,轻剪多留枝,以增加枝量,扩大树冠,促其成形。普通型品种树体高大,但萌芽率低。成枝力强,一
Apples are also different in pruning due to the large differences in their biological characteristics between spur-type and common-type varieties. First, young tree pruning. Spur type to promote the main type of ordinary slow-based. Spur breeds short tree species, internodes short, high germination rate, but weak branches, once the formation of short branches, into the results of the crown to expand very slowly, not easy to shape. Therefore, saplings should be primed to promote the main, let the branches let growth, as many branches, hair Wang branches, light cut more branches to increase the amount of branches, to expand the crown, and promote its formation. Ordinary varieties of tall trees, but low germination rate. A strong branch, one
