摘　　要：通过设置不同砧木年龄、粗度和高度,以及接穗粗度、芽数等几种处理,研究影响核桃嫁接苗成活及生长的主要因素。结果表明:成活率以子苗嫁接较高,高生长以1a生实生苗为砧木的嫁接苗最为迅速;砧木对嫁接成活率及生长的影响程度为:粗度>高度,且砧木以粗砧为好。子苗嫁接时,接穗应以1芽或2芽的嫁接成活率及高生长为佳;1a生实生苗嫁接时,接穗以2芽成活率较高,而生长情况则以1芽接穗较好;接穗对嫁接成活率及生长的影响程度为粗度>芽数,且以粗接穗为好。Dominant influence factors of survival ratio and growth of grafted walnut were studied under rootstocks of different age ,width and height, and scions of width and buds in this paper. The results were as follows：Survival ratio of seedling grafting was higher than that of 1-year-old seedling grafting, and sprout growth of 1-year-old seedling grafting was quicker than that of seedling grafting. The effect of rootstocks on survival ratio and growth of grafted walnut was width〉height, and wide rootstocks was good. Survival ratio and growth which scions had one or two buds was good by seedling grafting; Survival ratio with two buds of scions was good by 1-year-old seedling grafting, on the other hand, growth with one bud of scions was good; The effect of scions on survival ratio and growth of grafted walnut was width〉buds, and wide scions was good.
