摘　　要：连续3年对弱势苹果树进行研究,结果表明,采用重剪、回缩更新复壮的修剪方法后,树体通风透光性能改善,叶绿素含量和比叶重提高,光合作用增强,果实着色好,可溶性固形物含量和硬度也得到了提高,改善了果实品质,同时还增加了果实产量。Various pruning methods used old apple trees were studied for 3 successive years. The results showed that： After being pruned heavily, the transparency and ventilation of apple trees were improved; Photosynthesis was accelerated; Fruit oloring was much better; Soluble solid content and Hardness were increased; Fruit quality was improved; and yield was also increased.
