| 摘 要： | 设置非转基因抗虫棉棉田以及分别种植7和10 a转Bt基因抗虫棉的棉田3个处理,于2007--2008年棉花苗期、蕾期、花铃期和吐絮期采样测定了土壤中5个微生物种类的数量,以监测长期种植转Bt基因抗虫棉对土壤微生物群落生物多样性的影响.结果表明,3种类型棉田土壤细菌、真菌、固氮菌、反硝化细菌、亚硝化细菌数量以及微生物多样性指数在整个棉花生长期内变化趋势基本一致,其中,在棉花蕾期各种微生物数量达到高峰.与种植非转基因抗虫棉相比,不同种植年限转Bt基因抗虫棉对土壤细菌、真菌、固氮菌、反硝化细菌、亚硝化细菌数量和微生物多样性指数都无显著影响,但随着采样时间的不同,3种类型棉田土壤各类微生物数量和多样性指数都呈明显季节变化. |

| Abstract: | Transgenic Bt cotton has been released into the environment commercially for over 10 years in China,and its influence on soil microbes is an important part of biosafety research.To monitor impact of long-term cultivation of transgenic Bt cotton on diversity of soil microbial community,one cotton field where non-transgenic had been planted all along and other two cotton fields where transgenic Bt cotton had been planted for seven and ten years,respectively,were selected and soil samples were taken from these... |
| Keywords: | transgenic Bt cotton long-term planting soil microorganism environmental monitoring |
