Abstract Counting the number of bacteria、antinomyces and fungi in the soil after different years of planting Bt cotton.The results showed as follow：（1）the trend of influence of planting Bt cotton to the bacteria、antinomyces and fungi number in the soil is basically similar.（2）After one year of planting Bt cotton the number of bacteria、antinomyces and fungi in the soil would increase. With 4 successive years of planting，it reaches to the peak and then begins to fall. After 7 successive years the number even is close to that of 1 year.（3）After one year of planting Bt cotton and then one year of non-Bt cotton，the number of microbes in the soil is smaller than that of planting one year of Bt cotton which is close to the number of planting non-Bt cotton. So, there are some effects on the number of microbes in the soil, while planting Bt cotton for more years.
