摘　　要：研究结合太湖常熟市常福村示范田,提出了“深蓄减排、浅湿控灌、水肥耦合、渗滤控排、塘堰湿地”的农田径流氮磷高效去除模式,并通过技术集成示范,对TN、TP、NO3-N、NH4+-N等的拦截效果进行了研究。示范区建成后,水稻作物产量平均增加3.08 kg/hm2,生态系统对农田排水中TN、TP、NO3-N、NH4+-N去除率介于52.2%~67.1%之间,拦截效果均较为明显。研究结果为该地区农田径流面源污染防治及高标准农田生态体系构建提供理论依据及建设思路。This paper combines the demonstration field of Changshu City in the Taihu Lake Basin,and proposes“deep storage and emission reduction,shallow wet irrigation,water and fertilizer coupling,infiltration regulation,control drainage,pond wetland”efficient removal mode of nitrogen and phosphorus in farmland runoff.The interception effects of TN,TP,NO3-N and NH4+-N were studied through technical integration demonstration.After the completion of the demonstration area,the yield of rice crops increased by 46.2 kg/hm2 on average,and the removal rates of TN,TP,NO3-N and NH4+-N in farmland drainage were between 52.2%and 67.1%,and the interception effect was obvious.The research results provide theoretical basis and construction ideas for the prevention and control of farmland runoff non-point source pollution and the construction of high-standard farmland ecological system in this area.
