库尔勒香梨嫁接苗一般第3年就可少量开花,零星结果,第5年就有初步产量,进入初果期。但由于其干性强,幼龄树及初果期树在自然生长状态下枝条直立,树体抱合,树冠内膛郁闭,导致营养生长旺盛,6~7年生树依然结果甚少,极大地影响了早期经济效益。生产上常在5月中旬至6月下旬采用撑枝、拉枝技术削弱顶端优势,缓和生长势,促使侧芽发育,同时改变枝条伸展的方位角,使枝条在中心干周围按一定的开张角度均匀分布,促使形成合 Korla fragrant pear grafted seedlings in general the first 3 years can be a small number of flowering, sporadic results, the first 5 years there are initial production, into the early fruit period. However, due to its strong dryness, the young trees and early deciduous trees in the natural growth state branches upright, tree body cohesion, canopy canopy closed, resulting in vigorous vegetative growth, 6-7 year-old trees still very little results, greatly Affected the early economic benefits. Production often in mid-May to late June using brace, pull stick technology to weaken the top edge, ease the growth potential, to promote the development of lateral buds, while changing the azimuth of branches stretch, so that the branches in the center around the dry opening by a certain degree of uniform angle Distribution, prompting the formation of co-
