| 摘 要： | 为解决烤烟连作带来的减产降质、促进烤烟生产的可持续健康发展,研究了不同种植制度下烤烟根际土壤微生物群落的结构变化。结果表明：对于细菌群落结构,连作2a和5a细菌群落结构相似性高,与大豆-玉米-烤烟和玉米-大豆-烤烟根际细菌微生物群落差异大,而大豆-小麦-烤烟根际细菌群落结构处于中间位置。对于真菌群落结构,大豆-小麦-烤烟、大豆-玉米-烤烟和玉米-大豆-烤烟的根际真菌群落结构相似性高,连作2a和5a烟草根际真菌群落结构发生改变,且以连作5a处理的变化为大。说明连作烤烟根际微生物群落结构,特别是根际真菌群落结构改变可能在烟草连作障碍发生中起到重要的作用。 |

| Abstract: | To solve the yield reduction and quality brought by continuous cropping,promote sustainable development of flue-cured tobacco production,the change of microbial community structure on flue-cured tobacco soil rhizosphere in the different cropping systems was studied.The results showed that the similarity of flue-cured tobacco continuous cropping system in two and five years was higher for bacterial community structure.There were big differences for bacterial community structure with 'soybean-maize-flue-cured... |
| Keywords: | flue-cured tobacco rhizosphere soil microorganisms change |
