【摘要】：【目的】本文以利用年限分别为100、300、700、1000和2000年的水稻土及杭州湾海涂(0年)作为研究对象,探究对不同利用年限水稻土氨氧化细菌群落结构随着利用年限的变化而显著变化。【方法】采用PCR-DGGE技术分析6个利用年限水稻土的氨氧化细菌群落组成。【结果】利用PCR-DGGE得到的电泳图像显示不同利用年限水稻土样品可检测到的AOB的DGGE条带数量均存在明显差异。【结论】不同利用年限对水稻土氨氧化细菌群落结构产生较大的影响。
[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.
