摘要： 为了使中华金叶榆的芽接嫁接苗木当年成为商品苗，缩短培育周期，在传统“热粘皮”芽接技术的基础上研究开发新的嫁接技术“小枝冷粘皮”嫁接。采用“小枝冷粘皮”嫁接，就不同嫁接时间处理对中华金叶榆嫁接成活率、成苗率、苗木当年生长量进行了对比试验，筛选出最佳的“小枝冷粘皮”嫁接时期。结果表明，“小枝冷粘皮”和“热粘皮”2种嫁接的成活率并不存在明显差异，但“小枝冷粘皮”嫁接成苗率显著高于“热粘皮”，苗木当年平均生长量可以达到1.42m；结合苗木生长量确定4月15日—5月30日为“小枝冷粘皮”最佳嫁接时间。

Abstract: In order to make the Ulmus pumila cv.Jinye growing into commodity nursery stock in the same year and shorten the cycle of cultivation, the grafting skill with germination branches under low temperature was researched and developed on the basis of bud grafting. The writer adopted “grafting skill with germination branches” from different grafting time processing on the survival rate, seedling rate and seedling growth in through the contrast test. It selected the best grafting time. The results show that: graft survival rate of “grafting skill with germination branches” and “hot sticky skin” is not obvious difference, but the seedlings growth of “grafting skill with germination branches” can be achieved in the requirements. Combined with seedling growth, we sure April 15 to May 30 is the best grafting time for “grafting skill with germination branches”.
