摘    要:从吉林、黑龙江、北京、天津等地采集土样28份,经室内分离纯化后得到木霉菌(Trichoderma.spp)菌株60个,以立枯比丝核菌为供试病原菌,通过对峙培养筛选出1株对立枯丝核菌有强拮抗作用的木霉菌菌株,将其孢子悬液对茄苗不同时期进行人工接种测定其对立枯病的防治,结果表明:这种拮抗木霉菌对茄子苗期立枯病人明显的防治效果,子叶期防效达73.3%,真叶期防效达71.34%。

关 键 词:拮抗木霉菌  立枯丝核菌  拮抗作用  防效  蔬菜  苗期

Abstract:There were 28 samples of soil collected from Jilin,Heilongjiang,Beijing and Tianjin etc., and 60 strains of Trichoderma spp.were isolated.By antagonistical cultivation, we obtained one strain of Trichoderma spp. of high antagonistical action to Rhizoctonia solain . We also used suspender liquid of Trichoderma spores to control Rhizoctonia Wilt at different period of eggplant. The results show that effectiveness of Trichoderma spp.is 73.3% in period of cotyledon and 71.34% at true leaf period.
Keywords:Trichoderma  spp  Rhizoctonia solani  antagonistical cultivation  antagonistical effectiveness
