| 中文摘要: |
| 本试验旨在通过黄芪出苗率、根长、株高、增产率和对麻口病的防效等指标，以期筛选出对黄芪麻口病防治更加高效且对环境友好的生物药剂。生物菌剂混配撒施田间药效试验结果表明：各处理对黄芪产量和麻口病都具有一定的影响，其中10亿孢子/g金龟子绿僵菌和2亿CFU/g解淀粉芽孢杆菌处理组增产率和麻口病防效最高，分别为 58.37%和64.91%，与其他处理差异显著（P＜0.05）。菌剂各处理与对照相比对黄芪出苗率、根长和株高均无显著性差异（P＞0.05）。3种生物菌剂混配撒施均可有效防治黄芪麻口病，提高黄芪产量，因此,可广泛应用于实际生产。 |
| 英文摘要: |
| This study conducted a field efficacy experiment using broadcast-applied mixed microbial agents to evaluate their effectiveness in controlling numb mouth disease in Astragalus, aiming to identify environmentally friendly and highly effective biocontrol options. Evaluation indicators included seedling emergence rate, root length, plant height, yield increase rate, and disease control efficacy. The results showed that all treatments had a measurable impact on both Astragalus yield and disease incidence. Among them, the treatment composed of 1×108 spores/g of Metarhizium anisopliae and 2 × 108 CFU/g of Bacillus amyloliquefaciens achieved the highest yield increase (58.37%) and control efficacy (64.91%), with significant differences compared to other treatments (P < 0.05). There were no significant differences (P > 0.05) in seedling emergence rate, root length, or plant height between the treatments and the control. These results indicate that broadcast application of the tested microbial agents can effectively control numb mouth disease in Astragalus and enhance yield, demonstrating potential for practical application. |
