摘　　要：通过不同季节、不同嫁接方法进行了种鸡爪槭对比试验,以此分析影响大径阶砧木高位嫁接鸡爪槭接穗生长因素,试验结果表明:砧木可以是定植或移植;嫁接方法以枝芽接最好,可在春、秋季进行,切接易受风折;接芽外露可提早萌芽;接芽部位侧枝比主杆生长好,嫁接高度对接芽新梢生长影响不明显;遮阴保湿可以促进砧木和接穗新梢的生长,防止树杆灼伤;适时保留接芽上方的砧木萌条,可防止剪砧回浆,提高成活率。树冠恢复能力:鸡爪槭>紫叶鸡爪槭>红细叶鸡爪槭。This paper analyzes the factors that affect the growth of the Acer palmatumThunb top- grafted by large diameter group rootstocks through contrasting experiments on three kinds of Japanese maples grafted in different seasons and in different grafting methods. The results are as follows： Firstly, it has turned out that rootstocks can be field planted or grafted. As for the grafting methods, branch bud grafting which is often carried out in spring and au- tumn is the best one because cut grafting Acer palmatumThunb tend to be broken by wind. Secondly, grafted buds exerted can advance stem sprouting. In addition, lateral branches grow better than the main rod in the parts grafted while the grafting height has little influence on the growth of grafted bud shoots. Thirdly, shading and moisture retention can prevent the tree rod from being burned, promoting the growth of the rootstocks and the new grafted shoots. Finally, proper preservation of the rootstock＇s sprouted roots on the grafted buds can prevent the cut branches from pulp refluxing, improving the survival rate. As for the recover ability of the tree crown, the Acer palma- tumThunb is better than the Atropurpureum while the latter is better than the DissectumOrnatum.
