楝树嫁接育苗试验及影响因素分析

对楝树进行的不同嫁接方法、不同嫁接时间和对接穗采集时间及其处理不同的多水平试验结果表明，采用冬前采集经沙藏的接穗，在芽萌动膨大期运用芽接法嫁接育苗方法可行，培育出的苗木成活率高，可以在楝树无性苗木繁殖中推广应用。统计分析表明：接穗采集时间及处理因素在0．05检验水平上差异显著。

Experiment on Grafting Reproduction of Melia azedarach and Research on the Survival Factor

The different grafting methods, different grafting time, different scissoring time of scion and different treatments of Melia azedarach were studied. The results showed that it was available to use the bud grafting by the way in used the scion gathered before winter and dealed with sand and grafted in the time when its buds germinating and englagementing, the grafting survival rates was higher and could be widely applied in vegetative propagation of Melia azedarach. Statistical analysis showed that scion acquisition time and processing factors in the 0. 05 test level were significantly different.
