摘　　要：在大田和盆栽条件下,以转Bt基因抗虫棉晋棉26号和其具有相似遗传背景的普通棉花品种晋棉7号为材料,研究棉花不同生育期的土壤细菌、真菌、放线菌及其生理菌种的变化。结果表明,转Bt基因棉晋棉对土壤微生物种类和数量有一定的影响,在某些生育期显著高于或低于普通非转基因棉花,或者差异不显著。因此,转基因安全评价需要对土壤微生物进行评价。In order to evaluate the ecological risk of transgenic Bt cottor on soil microbe, field and pot experiments were conducted to study the effects of transgenic Bt cotton on soil bacteria, fungal, actinomyetes population and bacterial physiological group in Yuncheng, Shanxi Province and Hanzhou, Zhejiang Province. Jinmian 26 （transgenic Bt cotton variety） and its near - isogenic non - Bt counterpart Jinmian 7 were used. The results showed transgenic Bt cotton affected soil microbial population. At some growth stage, transgenic Bt cotton affected some soil microoial species significantly or not. So evaluation of transgenic Bt cotton on soil microbe was necessary to be conducted.
