Our experiment studied the changes of ammonia-oxidizing microorganisms in brown soil of northeast China after 38-year long-term fertilization, in order to add theoretical evidence for the role of ammonia-oxidizing microorganisms in the process of nitrogen cycling.本实验以中国东北棕壤为研究对象，探究其经38年长期施肥后氨氧化微生物（ammonia-oxidizing microorganisms）的群落变化，旨在为阐明氨氧化微生物在氮循环过程中的作用提供理论依据。
