目前梨树多用疏散分层形整枝,进入盛果后期,树体高大,树冠郁闭,内膛空虚,结果部位外移,产量开始下降,出现大小年。此时截除中干改疏散分层形为延迟开心形,以缩代疏,充实内膛,平衡树势,复壮结果枝组,是恢复和提高产量的有效措施。 At present, the pear tree is mostly divided into pruning branches by evacuation to enter the late stage of the full-blown fruit. The tree is tall, the canopy is closed, the inner cavity is empty, and the result site is relocated. The output begins to drop and the size of the year appears. At this point cut off in the dry change evacuation layered delamination happy-shaped, to reduce the sparse, enrich the bore, balance the tree potential, rejuvenation Zhizu group, is an effective measure to restore and increase production.
