用郯城９号、５号、１３号、１６号、３１３号、３１７号６个银杏品种进行嫁接试验，嫁接成活率均在８３．３％以上，品种间无明显差异，新梢生长量以郯城９号最大为４２．０ｃｍ，郯城９号等５个品种间无显著差异，均与３１３号（２１．２ｃｍ）有显著差异。以郯城９号为试材进行嫁接部位、接穗留芽数、接穗年龄及粗度试验，结果表明：嫁接部位在苗高５０～８０ｃｍ较好，成活率均在８５％以上，幼树生长旺盛；接穗留３芽成活率可达９０％以上，留单芽成活率仅６０％；接穗年龄对嫁接成活率影响不显著，但接后新梢生长以１～３年生较好；接穗粗度以０．４～０．９ｃｍ为好。
Grafting experiments were carried out on 6 varieties of Ginkgo biloba, including No. 9, No. 5, No. 13, No. 16, No. 313 and No. 317, the grafting survival rates were above 83.3%. There was no significant difference among the varieties. There was no significant difference among the five cultivars, such as No. 9, No. 42.0cm and No.9 of Yuncheng, all with 313 (21.2cm). The results showed that the grafting sites were better at the height of 50 ~ 80cm and the survival rates were over 85%, the saplings grew vigorously; The survival rate of scion spiked with 3 buds was more than 90% and the survival rate of single buds was only 60%. The scion age had no significant effect on the graft survival rate, but the shoots grew well after 1 to 3 years. .4 ~ 0.9cm as well.
