杭州种猪场鸽宝山果树队,近年来梨树主栽品种菊水梨(即浙江梨外销名牌商品-西湖蜜梨)成年树生长普遍偏旺,骨干枝延长梢一般长1米以上,有的长达1.3-1.4米,致使生长强的树冠早已封行,内膛下部光照不良,造成枝弱、光秃、花少、果少的上强下弱的局面.为此,我们从1974年开始,开展对成年菊水梨夏季修剪试验.经过三年来的边试验、边总结、边推广应用,在生产上获得了良好效果,扭转了上强下弱生长偏旺的局面,使产量产值提高.现将试验总结如下.
Hangzhou pig farms Baoshan fruit trees team, in recent years, the pear cultivars Kikusui pear (that is, Zhejiang pear export brand-name products - West Lake honey) grown generally more popular adult trees, branches extend the tip of the general length of 1 meter long, and some long Up to 1.3-1.4 meters, resulting in a strong crown of growth has long been sealed line, the lower part of the bad light in the lower part of the borehole, resulting in weak branches, bare, less flowers, less fruit on the strong weak under the situation.To this end, we started from 1974, Carry out the summer pruning test of juvenile pears pear after three years of side testing, while summarizing, while promoting the application of good results in production, reversing the strong growth of the weak under the conditions of partial growth, so that output value increased now The test is summarized as follows.
