翠冠梨主枝创伤处理控梢促花保叶效应试验

以10年生翠冠梨为供试品种，进行倒贴皮、环剥、环割等处理，探讨翠冠梨主枝创伤处理控梢、促花、保叶等效应。结果表明：翠冠梨主枝创伤处理，能有效抑制枝梢生长，缓和营养生长，促进花芽分化，提高坐果率，增产效应明显；叶部真菌性病害发生较轻，病毒性病害却呈加重发生趋势；对梨叶早衰脱落具有一定减轻发生程度与延缓发生过程作用。

The Effects of Injuring the Principal Branch of Cuiguan Pear on Controlling Shoot Growth, Improving Bloom and Protecting Leaf

In order to discuss the effects of injuring the Cuiguan principal branch on controlling shoot growth, improving bloom and protecting leaf, the ten years old Cuiguan pear were used to be experiment materials, which were treated by ringing, girdling, circled peel and lose in bargain skin respectively. The results showed that the treatment of injuring principal branch could control shoot growth, relax vegetative growth, improve flower bud differentiation, increase percentage of fertile fruit efficiently and increase yield significantly. In additionally, the leaf fungi diseases became light, but virus diseases became more and more severe. Injuring the principal branch also could reduce the leaf early senescence and defoliation and delay that occurring at some degree.
