摘　　要：为了寻找适合榉树新品种的繁殖技术,就采穗母树的树龄、扦插基质、激素种类和浓度对榉树扦插生根的影响进行了扦插繁殖试验。结果表明:随着采穗母树树龄的增加,榉树扦插生根率呈显著下降趋势,用以扦插的采穗母树以幼龄树比较合适;扦插基质以珍珠岩∶泥炭土等于3∶1的为好;榉树扦插用的激素以NAA与IBA混合使用的效果为好,其中以3.0 g.L-1的IBA和3.0 g.L-1的NAA混合的效果为最好,其生根率为58.7%。In order to find the propagation technology of Zelkova schneideriana,effects of age of donor plant of Z.schneideriana,cutting medium,and kinds and concentrations of hormone on cutting and rooting were researched.The results showed that with the age of donor plant increasing,rooting rate was significantly decreased,so young donor plant was optimal material.The optimal ratio of perlite to peat in medium was 3︰1.Effect of NAA and IBA used together was better than that of NAA or IBA used alone,in which 3.0 g·L-1 IBA in combine with 3.0 g·L-1 NAA had the highest rooting rate（58.7%）.
