摘　　要：核桃树高接是低产树品种更新的有效措施,但采用传统方块芽接法嫁接时间晚,新梢生长量小且发育不充实,越冬不安全。而5月20—30日采用嫩枝双舌接或嫩枝劈接法,嫁接成活率可达90%以上,嫁接成活新梢长度平均达40cm以上,粗度平均在1.7cm以上;嫁接时间较方块芽接提前10~20d。High grafting is an effective measure for low yield tree variety regeneration,but the traditional square bud grafting method is late,the growth of new shoots is small and the development is not full,and it is not safe to overwinter.On the other hand,from May 20 to 30,the grafting survival rate could reach more than 90%,the average length of grafted shoots was more than 40 cm,and the average thickness was more than 1.7 cm.The grafting time was 10~20 days earlier than that of square bud grafting.
