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%。
對影響江南榿木半木質化嫩枝扢插生根效果的植物生長調節劑、扢插基質、插穗粗度等兇子進行瞭試驗研究。結果錶明,在全光照自動間歇噴霧條件下,江南榿木插條生根率及根繫生長等指標因植物生長調節劑IBA的質量濃度、基質的種類及配比組閤和插穗的粗度的不同有明顯差異。在生長旺盛夏季的6月至8月,選擇0.7~0.8em粗度插條,使用800mg/LIBA浸泡處理1min後,扢插于泥炭土:礱糠灰:珍珠巖體積比為1:1:1的混閤基質中,45d成活率可達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.
