| 中文摘要: |
| 研究了豆饼粉、泥碳土、木屑、KCl和尿素按不同配比制成的4种配方的存活基质对生防菌ANIT-8098A在室内的保存、田间防效和土壤定殖能力的影响。试验结果表明:用8.0%豆饼粉、46.0%泥炭土、40.0%木屑、5.0%KCl、1.0%尿素制成的生防菌制剂ANIT-3号存活基质对生防菌ANIT-8098A室内保存效果最好,经90 d后保存率仍高达83.33%;生防菌制剂ANIT-3号在田间对茄子青枯病的防效最高,达100.00%;生防菌制剂ANIT-3号对生防菌ANTI-8098A在土壤中定殖力的促进效果也最高,药后40 d定殖率为11.2%。 |
| 英文摘要: |
| The bacterium strain Anti-8098A(Bacillus cereus) was used as a biological agent to control bacterial wilt(Ralstonia solanacearum).To enhance the disease-control efficacy of ANTI-8098A in the field,the effects of different medium formula on preservation,control efficacy and soil fixability of Anti-8098A were studied.Four different biological antiseptics,named ANTI1,ANTI-2,ANTI-3 and ANTI-4,were prepared using four different media and ANTI-8098A fermentation liquids.The results showed that ANTI-3,the medium of which was composed of 8% bean powder,46 % turf soil,40 % wood crumb,5% KCl and 1% urea,had the highest conservation ratio of ANTI-8098A,that is 83.33 % after preservation for 90 days.Meanwhile ANTI-3 also showed the best control efficacy,100.0 % control of eggplant bacterial wilt disease and the highest fixability of soil. The reason might be that the bean powder,turf soil and wood crumb could supply ANTI-8098A with nutrition and keep it growing,while KCl could prevent the nutritional components from decaying and urea constantly release ammonia to slower the respiration of ANTI-8098A and enhance its survival ability. |
