摘 要 ：以琴叶变叶木（Codiaeum variegatum var .pictum）为材料，用1%三唑酮+15%乙蒜素可湿性粉剂（三乙）和15%多菌灵+15%福美双可湿性粉剂（多福）分别配制成不同浓度的系列溶液，对插穗浸泡处理3 h后扦插试验，研究这两种混合杀菌剂对插穗的影响。结果表明，三乙和多福处理的最佳插穗平均生根数、平均根长、平均根直径、成活率分别高出对照26.2、15.4 mm、0.25 mm、60%和9.6、7.4 mm、0.36 mm、46.67%，与对照的差异均极显著（p＜0.01）。结果还表明，三乙和多福浸泡3 h的理论最佳浓度分别为1.819 g L-1和1.894 g L-1，三乙浸泡优于多福（p＜0.01）。
Abstract:Softwood cuttings of Codiaeum variegatum var.pictum were treated with diffrent concentrations of solutions 1 (1％Triadimefon +15％Ethylicin WP) and 2 (15％Carbendazim + 15％Thiram WP)for 3 hours. Compared with control, new roots, root length, root diameter and survival rate increased by 26.2, 15.4 mm, 0.25 mm, 60%, respectively in solution 1 treatment, and they increased by 9.6, 7.4 mm, 0.36 mm, 46.67% , respectively in solution 2 treatment. The statistical analyses indicated that the optimal concentrations of solutions 1 and 2 were 1.819 g L-1 and 1.894 g L-1, respectively. In addition, solution 1 was more effective than solution 2（p＜0.01）.
