The effects of transgenic insect-resistant cotton with different planting years on soil microbe were studied.The result showed that the average number of soil microbe was 111.62 million per gram dry soil in different cotton field.The number of bacteria was 93.70 million,accounted for 83.95% of the total microbe with the absolute dominance and the ratio showed that the bacteria was the main microbe in the cotton field.The second was the actinomyces with the ratio of 14.44%.The fungus was the least,accounted for 1.62%.In three different stage of cotton growing,the number of bacteria,fungi and actinomyces in different cotton field reached top in the cotton field that planting transgenic insect-resistant cotton four years.The number of the bacteria changed obviously,the number of fungi increased straightly;and the number of the actinomyces decreased straightly in general.The results showed that transgenic insect-resistant cotton could influence the number of the soil microbe,and the cotton field of different years for planting transgenic cotton affected the number of microbe differently.
