本研究运用嫁接愈合原理，结合山核桃生物学习性，分析了山核桃嫁接成活的主要抑制因子；通过变换嫁接时间和操作方法，以及优选接穗类型、砧木等技术试验，把山核桃嫁接成活率提高到了８８％；进而以野生化香为砧木，就地嫁接后简单管理使平均成活率达到了５９％；且嫁接苗生长良好，当年平均高０．９５ｍ，是一年生实生苗高的４倍，平均地径１．２ｃｍ，前期表现较强的亲和性。 In this study, the principle of grafting healing, combined with the biological behavior of pecan, analyzed the main inhibitory factors of grafting survival of hickory. The grafting survival rate of pecan was increased by changing the grafting time and operation method, and the optimal scion type, rootstock and other technical tests To 88%; and then the wild-flavored incense as rootstocks, simple management after grafting in situ so that the average survival rate reached 59%; and grafted seedlings grew well, the average high 0.95m, 4 times the annual seedling height, the average 1.2cm diameter, early performance of strong affinity.
