一、解决光照问题疏除树体膛内部分轮生、重叠、交叉的大枝，对密生枝视情况可疏除，其余枝条改造大、中、小型枝组，使全树大枝稀密适当，布局合理，通风透光良好。二、解决更新问题对骨干枝的更新。后部光秃、结果能力差的老龄枝进行重回缩，控前促后，剪截量控制在原校的１ First, to solve the problem of light sparse Tree body part of the rotation, overlap, cross the branches, depending on the conditions of dense branches can be sparse, and the remaining branches of large, medium and small Zhizu, the whole tree big branches appropriate density, layout Reasonable, well-ventilated and well-ventilated. Second, to solve the update problem on the backbone of the branch update. The back of the bald, the poor ability of aging branches to re-retraction, control before the promotion of shear cut-off control in the original school 1
