中文摘要：
本文对核桃在青海循化地区嫁接的主要技术环节进行了试验,结果表明：覆地膜可以促进苗木的生长发育;不同的嫁接方法要选择适宜的嫁接时期,在适宜的嫁接时期内,绿枝接和芽接的成活率要高于子苗嫁接;各嫁接方法的新梢粗度无明显差异;从苗高和地径上看,绿枝接和芽接生长都大于子苗嫁接,绿枝接苗木生长优于芽接。
英文摘要：
The walnut grafting （seeding grafting, budding and scion grafting ）was studied at Xunhua in Qinghai. The results showed that covering with ground film could promote the growth of seedlings. The different grafting methods ought to select appropriate grafting time, at an appropriate grafting period, the survival rate of budding and scion grafting was higher than that of seeding grafting. The various grafting methods had no significant difference in shoot diameter. The seedling height and diameter of scion grafting were greater than budding grafting, and the seeding grafting was the smallest.
