不同嫁接方法对珙桐成活率的影响

Effects of Different Grafting Methods on Survival Rate of Davidia involucrata Baill.

通过使用切接、劈接、腹接、皮下接、T型芽接、嵌芽接6种不同的嫁接方法,观察嫁接后的成活率与植株的生长状况,研究6种不同嫁接方法对珙桐成活率及成活后生长状况的影响。结果表明,成活率由高到低的嫁接方法依次为嵌芽接、切接、劈接、T型芽接、皮下接、腹接;生长状况由好到差依次为切接、劈接、皮下接、腹接、嵌芽接、T型芽接。

By using six different grafting methods,including cut grafting,cleft grafting,side grafting,crown grafting,T type budding and chipbudding,survival rate and growth of the plant after grafting were observed,and the effect of six different grafting methods on survival rate and growthstatus after grafting of Davidia involucrata Baill.were studied.The results showed that survival rate from high to low were in turn of chip budding,cutgrafting,cleft grafting,T type budding,crown grafting and side grafting;growth status from good to bad were in turn of cut grafting,cleft grafting,crowngrafting,side grafting,chip budding,T type budding.
