主侧枝开展角度过小时,树势易过旺,内膛不开阔,光照不充足,小枝少而瘦弱,有效短枝少,结果晚,产量低。适当加大主侧枝的开展角度,有利于缓和生长势,促进萌芽和增加早期封顶枝;内膛开阔,空间较大,光照充足,小枝多而充实;骨干枝易于前后平衡,有利于结果 The main side branches to carry out the angle is too small, the tree potential is too prosperous, the bore is not open, inadequate illumination, twigs less thin, less effective short branches, the results of late, low yield. Appropriate to increase the main branch of the angle, is conducive to ease the growth potential, promote germination and increase the early capping branch; bore wide, large space, adequate illumination, twigs and more substantial; backbone of the branch is easy to balance before and after, is conducive to the results
