| 摘 要： | 采用木霉菌（Trichoderma asperellum）和木霉粉剂，通过平板对峙培养法，进行了木霉菌对黄瓜枯萎病菌的体外抑菌活性（ECS0）测定和棚室小区试验对黄瓜猝倒病和枯萎病防效及生长发育的调查。结果表明，木霉菌对黄瓜枯萎病菌（Fusarium oxysporum f. sp．cucttmarirtttm）的致死中浓度约为535个孢予mL^-1，可见木霉对黄瓜枯萎病菌具有很强的抑菌能力；木霉粉剂对黄瓜猝倒病的防治效果为54．4％，对黄瓜枯萎病的防治效果最高可达89．5％。同时木霉粉剂对黄瓜有促进提早开花和增产作用。图3，表4，参13。

| Abstract: | In this study, we conducted a lab bioassay and field trial with Trichoderma asperellum and Trichoderma spp. against cucumber damping-off disease caused by Fusarium oxysporum f. sp. Cucumarinum. The result shows that the EC50 of Tr/choderma against Fusarium oxysporum f. sp. Cucumeris was 535 spores/ml. We concluded that Tr/choderma has a great efficacy against pathogens. The control rate on cucumber damping-off disease was 54. 4% , Fusarium oxysporum（SChl） f. sp. cucumerinum was 89. 5%. It was also found that the application of Trichoderma agent enhanced the cucumber flowering and yield. |
