新金县第四中学、双塔公社双塔大队,为了提高旺树产量,使幼苗提早结果,他们于1969年对留做桥接的旺枝,在萌芽后进行了短剪,发现有缓和生长势、促进芽萌发的作用。在这一现象的启示下,于1970～1972年连续3年进行了晚春修剪试验,获得了较好效果。试验表明:晚春修剪是一项缓和树势,提高萌芽率,促进花芽形成,使旺树提早结果的有效措施。特别是对萌芽率低的小国光品种的旺树旺枝,效果更为明显,可以提高萌芽率20～40%,最高达60%,能克服该品种因萌芽率低而造成“光杆”现象;部分短枝当年即可形成花芽;使延长枝生长势趋向中庸。
Xinjin County Fourth Middle School, Twin Towers Commune twin towers brigade, in order to improve the production of Mongolian trees, so early seedlings results, they stay in 1969 for the bridge to stay Wang Chi, after the sprout in a short shear and found to ease the growth potential , Promote bud germination. Inspired by this phenomenon, the late spring pruning test was carried out for three consecutive years from 1970 to 1972, obtaining good results. Experiments show that: pruning in late spring is an effective measure to alleviate the tree vigor, improve the germination rate, promote the flower bud formation and make the Mongolian tree early result. Especially for the low germination rate of Wangguangwangwang branches, the effect is more obvious, can increase the germination rate of 20 to 40%, up to 60%, to overcome the variety due to the low rate of germination caused by the “polished rod” phenomenon; Part of the spur to form flower buds that year; to extend the trend of growing branches tend to moderate.
