摘　　要： 以琴叶变叶木(Codiaeum varie gatum 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3h后进行扦插试验,研究这两种混合杀菌剂对插穗生根的影响。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、15.4mm、0.25mm、60%和9.6、7.4mm、0.36mm、46.67%,与对照比较差异达极显著水平(P!0.01)。三乙和多福浸泡3h的最佳浓度分别为1.819gL-1和1.894gL-1,三乙浸泡优于多福(P!0.01)。 Softwood cuttings of Codiaeum variegatum var. pictum were treated with different concentrations of solutions 1 （1% Triadimefon ＋ 15% Ethylicin WP） and 2 （15% Carbendazim ＋ 15% Thiram WP） for 3 hours, respectively. Compared with control, rooting number, root length, root diameter and survival rate of softwood cuttings increased by 26.2, 15.4 mm, 0.25 mm, and 60%, respectively in solution 1 treatment, and by 9.6, 7.4 mm, 0.36 mm, and 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）.
