| 中文摘要: |
| 通过随机区组试验，研究了施用枯草芽胞杆菌( Baci l l ussubt i l i s) BLG01 与覆盖对香蕉长势、枯萎病病情
指数、枯萎病病原菌（Fusar i um oxyspor um f .sp.cubense,FOC）与可培养细菌数量的影响。结果表明，与对照比较，在香
蕉移栽 100 d 时，不同覆盖模式下，施用 BLG01 能促进香蕉生长和提高枯萎病防治作用，其中以玉米覆盖与共同施
用 BLG01防治作用最显著，香蕉株高、茎围、地上部、地下部鲜重和防效显著提高，病情指数下降了 43. 07% ~60. 56% ，
根际 FOC 的 l ogCFU 降低了 72. 15% ~131. 18% ，可培养细菌数量的 l ogCFU 增加了 31. 21% ~35. 02% ；相关性分析表明，
FOC 与细菌数量呈显著负相关关系， 与病情指数呈极显著正相关关系。 施用枯草芽胞杆菌结合覆盖可促进香蕉生
长，降低枯萎病病原菌数量，提高根际可培养细菌数量，增加对香蕉枯萎病的防治效果 |
