通过不同激素、不同激素浓度、不同浸泡时间对金叶榆进行嫩枝扦插试验，结果表明：激素浓度是影响金叶榆扦插生根率、生根数量的显著因子，是影响生根长度的极显著因子，而激素种类和处理时间对生根影响不显著；确定采用ABT1＃200×10-6处理2 h ，生根效果最好，生根率达到80％，平均根量为12个，平均根长9．2 cm。

Experiments of different hormones ,different hormone concentrations and different soaking time on soft-wood cuttings of Ulmus pumila were conducted .Result shows that :hormone concentrations are not only the sig-nificant factor affecting rooting rate ,rooting number of Ulmus pumila‘Jinye’ ,but also the very significant factor affecting the root length ;hormone type & treatment time have no significant effect on rooting ;it determined that a-dopting ABT1 # 200 × 10-6 with 2 h can obtain the optimal rooting effect ;rooting rate reached 80% ;the root mass are 12 ,and the average root length being 9 .2 cm .
