摘要
综述了脲酶抑制剂/硝化抑制剂对土壤氮的转化过程:尿素水解过程、硝化过程、硝酸盐淋溶过程、反硝化过程、微生物固持过程、N矿化过程及气体挥发过程的影响和抑制剂的作用机理,并提出今后研究的发展方向,为今后如何施用抑制剂来提高土壤中氮素利用率和减少环境污染提供一定的参考价值。
In this paper, the effects of urease and nitrification inhibitors on soil N transformation including urea hydrolysis, nitrification, nitrate leaching, denitrification, microbial immobilization, N mineralization and gassy volatilization, and their action mechanisms were reviewed, and some comments on their further study were put forward, which could be helpful to the application of these inhibitors in promoting soil-N utilization efficiency and mitigating environmental N pollution.
