According to the variance analysis,the ammonifying bacteria and nitrifying bacteria quantities of RRS in the rhizosphere soil were much lower than that of other genotype soybeans.The effects of different genotype soybeans on ammoniation intensity and nitrification intensity were remarkable.The nitrification intensity and the nitrifying bacteria had the great positive correlation and sustainable development. 关键词：氮转移土壤生物学细菌生物
