摘　　要：对邓恩桉不同年龄母株上的嫩枝插穗以不同浓度ABT6号生根粉处理,并在不同时间进行扦插试验,结果显示:①500×10-6ABT6号生根粉处理邓恩桉嫩枝插穗,其扦插成苗率最高;②初夏扦插成苗率最高;③当年生邓恩桉母株上的嫩枝扦插成苗率最高。Through E. dunnii softwood cuttings seedling taken ABT6 powder of different concentrations, and different time and different age groups and parent stock for the softwood cuttings, the results showed： ① 500 ppm ABT6 powder for Eucalytus dunnii softwood cutting wasthe highest rate of seedling; ② In cutting time, the highest survival rate of seedling was in early of summer; ③ The highest survival was using the softwood of the current-year-planting mother tree Eucalytus dunnii.
