分4个不同时期进行芽接试验，结果表明，北美豆梨在春季树液开始流动后（4～9月）均可进行贴芽嫁接，但在夏季高温季节要注意保湿，贴芽接成活率可达84％以上；分析比较了贴芽、劈接、插皮接3种方法对嫁接成活率及芽萌动时间的影响，3种方法嫁接成活率分别为85％、80％、79％，芽接萌发时间主要集中在接后第12～16天，劈接和插皮接萌发时间主要集中在接后第14～18天。

The grafting experiments of Pyrus calleryana were done in four different periods .The results were as follows:grafting with sticking a bud could be conducted after the sap began to flow ( between April and September ) , and more attention should be paid to moisture preservation in summer;its survival rate could be above 84%.The effects of three grafting methods containing sticking a bud , cleft grafting , skin receiving on survival rate and bud stirring time were studied , and their survival rate was 85%, 80%and 79%respec-tively .The bud stirring time of sticking a bud mainly focused on the 12 nd~16 th day after grafting , while that of cleft grafting and skin receiving mainly focused on the 14 th~18 th day .
