摘　　要：为提高千阳县较高海拔(1400~1500 m)区域低产核桃园经济效益,在该县高崖镇以优良鲜食核桃品种西林3号为材料,比较研究了枝接、芽接高桩枝接、芽接等不同高接换头嫁接方法的嫁接成活率、新枝数量及其生长量,结果为芽接成活率75.8%,枝接成活率68.2%,前者略高于后者,二者差异不明显;枝接平均萌枝数量、萌枝长度高于芽接,差异显著;当年平均萌枝数枝接1.94个、芽接1.0个,萌枝径生长量枝接0.88 m、芽接0.44 m,差异都显著。宝鸡市高海拔地域核桃低产园改造时,应尽量采用低桩多砧(2~3个)芽接方式。Based on the investigation and analysis of the grafting and germination survival rate and grafting growth of Xilin 3,an excellent fresh walnut variety introduced during the transformation of walnut low-yield orchard in Gaoya Town,Qianyang County,Baoji City,Shaanxi Province,two top grafting methods,branch-grafting and bud-grafting,were compared.The result showed that bud-grafting had higher survival rate than branch-grafting,75.8%and 68.2%respectively.However,the average number of shoots and length of shoots from branch-grafting were 1.94 and 0.88m respectively,higher than those from bud-grafting,that is 1.0 and 0.44m respectively.Callusing degree of branch-grafting reached 25%,higher than that of bud-grafting.
