对七年生苹果梨层面非骨干枝进行了环剥试验，试验结果（环剥比对照枝显著增加花芽形成量。枝干直径的１／１２，１／１０，２／１０及对照四个处理差异极显著。在６月１０日、６月２０日、６月３０日及７月１０日４个时期环剥中，前３个时期无显著差异，而７月１０日处理有显著差异。试验中发现，６月１０日以前环剥，剥口不宜小于１／１０，１／１２的剥口愈合快，不能充分起到环剥的作用，而６月３０日以后剥口不宜大于１／１０，２／１０剥口不易愈合影响枝条生长甚至倒置枝条死亡。环剥对枝干粗度的增长无显著影响。本次试验中最佳组合是６月１０日的２／１０处理，６月２０日的２／１０处理和６月２０的１／１０处理。
The results of the girdling test showed that the number of flower bud formation was significantly increased in the ring petioles compared with the control branches. The differences in the diameter of the branch stems were 1/12, 1/10, 2/10 and the control four treatments Extremely significant in the June 10, June 20, June 30 and July 10 in the four periods of girdling, the first three periods were no significant differences, while the July 10 treatment was significantly different in the experiment Found that before June 10 girdling, the skin should not be less than 1 / 10,1 / 12 of the wound healing, can not fully play the role of girdling, and June 30 after the mouth should not be more than 1/10, 2/10 peeling is not easy to heal the growth of branches and even the death of upside branches.Grape peeling has no significant effect on the growth of the branches.The best combination in this experiment is the 2/10 treatment on June 10 and June 20 2/10 and June 20 1/10.
