一、梨树树体高大,干性强,生长慢,寿命长在相同管理条件下,同龄梨幼树和苹果树相比,梨树的冠径小、干周细、树冠呈圆锥形;但结果后,尤其到盛果期之后,树形较苹果树开张。所以,梨幼树整形修剪时,应比苹果树轻些;要及时而适当地控制中心干的生长势和上升速度,以促进其他枝的长势。二、梨树萌芽率高而成枝力低梨树的多数品种萌芽率较高,成枝力较弱,所以整 First, the pear tree tall, dry strong, slow growth, long life Under the same management conditions, the same age pear and apple trees, pear crown diameter small, dry weeks, the crown was conical; but After the results, especially after the full fruit period, the tree is opened to apple trees. Therefore, pear saplings plastic trim should be lighter than the apple tree; to timely and appropriate control of the growth of the center of dry and rising speed, in order to promote the growth of other branches. Second, the pear sprouting rate is high and the branch force is low Most varieties of pear higher germination rate, weaker branch force, so the whole
