经 8年系统试验研究从 330个细菌菌株中筛选出 1株防病促生枯萎病拮抗菌“98 Ⅰ” ,经鉴定属蜡质芽孢杆菌。该菌对黄瓜枯萎病、西瓜枯萎病、青椒枯萎病和番茄枯萎病 4种土传病害均有显著防治效果 ,其平皿孢子萌发抑制率分别为 79 2 %、75 1%、72 3%和 95 7% ,且该菌对多种蔬菜有促生和促进种子发芽功效。 After 8 years of systematic experimental research, one antagonistic bacterium “98 Ⅰ” for preventing and treating Fusarium wilt was screened from 330 bacterial strains and was identified as Bacillus cereus. The fungus had significant control effects on four kinds of soil-borne diseases such as cucumber wilt, watermelon wilt, green pepper wilt and tomato wilt. The inhibition rate of the fungus to the soil was 79 2%, 75 1%, 72 3% and 95%, respectively 7%, and the bacteria on a variety of vegetables to promote growth and promote seed germination.
