梨树进入结果投产期,其生产量大,先端生长较旺盛,易形成外强内弱,上强下弱,外围枝多的情况。此时应以整形,扩大树冠和促生大量果枝,控制外围不使其生长过旺为主,又要保证向外延伸的先端优势,并要求膛内多发短枝,增大角度,张开骨架,控制树冠上升过快,使膛内枝组得到较足的养分, Pear into the results of the commissioning period, the production of large, more vigorous growth of the front, easy to form strong outside the weak, strong on weak, peripheral branches and more. At this point should be shaping, expanding the crown and promote large numbers of fruiting branches, the control of the external growth is not over-based, but also to ensure the outward extension of the advantages of the front, and require more muffles in the bore, increase the angle, open Skeleton, control canopy rose too fast, so that the inner branch group get more adequate nutrition,
