| 摘 要： | 为了探索防治烟草青枯病的农艺栽培措施,于2008和2009年通过田间小区试验考察了地膜覆盖、水稻秸秆覆盖及黑麦草等覆盖对连作烟草青枯病的防治效果,并分析了不同覆盖模式对土壤青枯菌,土壤可培养细菌、真菌和放线菌种类及数量的影响.结果表明:膜草覆盖和前膜后秸覆盖均能有效防治烟草青枯病,在移栽后4周和采收末期的防效均达到65％以上,单一黑麦草覆盖或单一秸秆覆盖的防效仅为32％～62％;不同覆盖模式对土壤微生态的影响效果不同,盖膜和种植黑麦草处理,其移栽后1周、4周的相对抑菌率均达75％以上,前膜后秸在栽后1周、4周的相对抑菌率均达到74％以上;膜草覆盖和前膜后秸均能增加土壤可培养细菌的种类,但对真菌和放线菌的种类影响不大,因此,膜草覆盖和前膜后秸两种覆盖模式在防治青枯病方面具有较高的实用价值. |

| Abstract: | In order to explore the agricultural measures for controlling tobacco bacterial wilt disease,the effects of film mulching,rice straw mulching,and ryegrass planting on the disease were investigated with field plot trials in 2008 and 2009.The influences of tested treatments on Ralstonia solanacearum and the species and populations of soil culturable microbe,including bacteria,fungi and actinomycetes,were analyzed.The results indicated that the combination of film mulching and ryegrass planting and the mode of... |
