[Abstract]:[objective] in this paper, the paddy soil and the coastal zone of Hangzhou Bay in 2000 were used as the research objects. The structure of ammonia-oxidizing bacteria community in paddy soils with different utilization years was studied. [methods] the composition of ammonia-oxidizing bacteria community in 6 paddy soils with different utilization years was analyzed by PCR-DGGE technique. [results] The electrophoretic images obtained by PCR-DGGE showed that there were significant differences in the number of AOB bands detected in paddy soil samples with different years of use. [conclusion] different utilization years had a great influence on the structure of ammonia-oxidizing bacteria community in paddy soil.
