【摘要】 对农田土壤氮素淋失的相关研究进行综述和总结是研究农业面源氮素污染的一个至关重要的前提。本文从土壤氮素渗漏淋失形态和迁移机理、氮素渗漏淋失的研究方法和影响土壤氮素渗漏淋失的因素三方面进行了详细的分析介绍,概述了近年来国内外农田氮素渗漏淋失的研究进展和研究成果,并在此基础上展望了未来氮素淋失研究工作的重点。研究结论对农田土壤的水肥管理措施及浅层地下水硝氮污染的减缓有一定的理论和借鉴意义更多还原

【Abstract】 Reviewing and summarizing the related research of farmland soil nitrogen leaching loss is a crucial basis of studying agricultural non-point source of nitrogen pollution. This paper introduced and analyzed the leaching form and migration mechanism of soil nitrogen,research methods and influencing factors of nitrogen leaching in farmland soil. The recent research progress of nitrogen leaching in farmland soil at home and abroad was summarized,and the future research priorities were pointed out. The research conclusions have some reference values on farmland soil fertilization management measures and slowing down the nitrate nitrogen pollution in shallow groundwater.更多还原
