对影响江南桤木半木质化嫩枝扦插生根效果的植物生长调节剂、扦插基质、插穗粗度等凶子进行了试验研究。结果表明，在全光照自动间歇喷雾条件下，江南桤木插条生根率及根系生长等指标因植物生长调节剂IBA的质量浓度、基质的种类及配比组合和插穗的粗度的不同有明显差异。在生长旺盛夏季的6月至8月，选择0．7～0．8em粗度插条，使用800mg／LIBA浸泡处理1min后，扦插于泥炭土：砻糠灰：珍珠岩体积比为1：1：1的混合基质中，45d成活率可达92．3％。

The experiment on the growth regulators, substrates and roughness of cuttings which affect the rooting of the semi - hardwood tender branch cutting of Alnus trabeculosa Hand. - Mazz. in the growth period showed that there were obvious difference of rooting rate and root growth with different IBA densities, types and proportions of substrates, and roughness of cuttings. The survival rate of 45 d could reach above 92. 3% , when the 0. 7 -0. 8 cm roughness cutting woods were treated by 800 mg/L IBA for one minute and then cut into the composite base material which was comprised of sand, rice chaff ash, pearlite at the ratio of 1： 1： 1 （V： V： V） from June to August.
