摘　　要：用三唑酮＋乙蒜素（1：15）混合配制160-1600mg/L10种不同浓度的药剂，分别对鹅掌柴插穗浸泡处理后扦插。结果表明，最佳处理的插穗生根数、根长、新枝长的平均值和最高成活率分别为39．7条、18．67mm、47．25mm、100％，分别比对照高出7．3条、2．54mm、17．15mm、46．67％，所测指标均与对照的差异显著（P〈0．05）；在160-400mg/L，处理浓度与以上各指标的关系均符合二次曲线模型（R^2〉0．96）；根径、小叶数、生枝数与对照差异不显著。Cutting propagation experiments of S. octophylla were conducted by dipping treatment of cuttings with 160-1 600 mg/L wettable powder mixture of 1% triadimefon ＋ 15% ethylicin. The results showed that under the optimal treatment, the measured indexes of rooting number per cutting, root length, new branch length and survival rate were respectively 39.7, 18.67 mm, 47.25 mm and 100%, and increased respectively by 7.3, 2.54 mm, 17.15 mm and 46.67% over the control group. The differences in all the measured indexes between the optimal treatment and the control were significant （P〈0.05）. Within range of 160-400 mg/L, the relationships between the treatment concentration and the above indexes were all in line with quadratic curve model （R^2〉0.96）. There were not significant differences in the root diameter, leaflet number and branching number between the optimal treatment and control.
