摘　　要：[目的]探讨木霉菌与内生细菌防治甜瓜枯萎病的协同增效作用。[方法]在离体和活体条件下,研究了木霉菌T23和Ta22分别与内生细菌B6和B20-006复合使用对甜瓜枯萎病的防治效果。[结果]内生细菌B6和B20-006不论是与木霉菌T23复合处理还是与Ta22复合处理的防治效果均高于4个生防菌单独处理,其中B6+T23和B20-006+Ta22 2个复合处理的相对防效分别高达82.2%和81.0%。[结论]应用内生细菌与木霉菌复合防治甜瓜枯萎病有明显的协同作用。[ Objective] The aim was to explore the synergistic effect of Trichoderma and endophytic bacteria against muskmelon wilt. [ Method] The control effects of Trichoderma 3＂23 and Ta22 combined with endophytic bacteria B6 and B20-006 against muskmelon wilt were studied under in vitro and in vivo conditions. [ Result] Relative control effects of combined treatments of B6 ＋ T23 and B20-006 ＋ Ta22 against muskmelon wilt were 82.2% and 8l. 0%＇respectively in pot ,which were higher than single treatment with Trichoderma T23 and Ta22 or endophytic bacteria B6 and B20-006. [ Conclusion] Trichoderma and endophytic bacteria have obvious synergistic effect against muskmelon wilt.
