以当年生和2年生枝条为扦插材料,用不同处理方法对常绿白蜡进行扦插育苗试验,考察影响常绿白蜡扦插生根的主要因子,结果发现激素种类为影响常绿白蜡嫩枝扦插生根主要因素,其次是插穗类型和浸泡时间,激素浓度影响较小。试验分析表明当年生枝条扦插生根效果比2年生枝条扦插生根效果更好。常绿白蜡嫩枝扦插试验最佳处理为取当年生枝条中部用浓度为500mg/kg的ABT生根粉1号溶液快浸10s,扦插后60天生根率达60%。
The experiment on cutting propagation was carried out by using 1 or 2-year-old branches and different method to search the main factor which affects the rooting of Fraxinus griffithii. The result showed that the main influenced factor was hormone type, cuttings type and soak time were the next factor. The influence of hormone ' s concentration was lower. The rooting effect of 1-year-old saplings was better than those of 2-years-old. The best treatment of softwood cutting propagation was that using the middle part of 1-year-old branches as material, soaked the base for 10 seconds by ABT1 with the concentration of 500 mg/L. The rooting rate would reach over 60% after 60 days.
