培育银杏嫁接苗，通常都采用2—3年生实生苗作砧木。我们通过秋、春两季试验，采用1年生实生苗作砧木，同时进行4种嫁接方法比较，其中顶芽劈接嫁接成活率达100%，平均高可达60．70cm，枝径1．04cm，而且苗木质量好。
Breeding ginkgo grafted seedlings, usually 2-3 year-old seedlings for rootstocks. Through the autumn and spring seasons, we used 1-year-old seedlings as rootstocks and compared 4 grafting methods. The survival rate of top buds was 100%, average height was 60.70cm, branch diameter 1.04cm , But also good quality seedlings.
