摘  要：
为了研究不同灌排模式稻田排水中氮磷流失规律,以集成合理的节水灌溉与控制排水技术,在江苏高邮开展田间试验。试验区排水斗沟出口处设水位调控闸门,在水稻不同生育阶段对排水沟水位及田间水分进行控制,形成新型的控制灌排模式。与常规灌排模式进行对比,两年田间试验成果表明,控制灌排模式较常规灌排模式节水16.7%,增产7.1%,排水总量减少54%,水稻全生育期稻田排水中NH4+-N、NO3--N与TP流失总量分别减少38.07%、82.29%和52.15%,节水减排和降污效果显著。采用控制灌排模式,通过实施灌水调控和排水管理,控制了氮磷流失关键时期的排水量,高效利用了水分和养分,取得了节水高产、减排控污的效果。

摘  要：
A field experiment was performed in Gaoyou City,Jiangsu Province,to study the nitrogen and phosphorus losses under different irrigation and drainage mode and to integrate scientific irrigation and drainage technology.By setting water-controlling strobe at the ditches in the experiment plot,the drainage was regulated to different growing stages.Two years' experiment demonstrated that controlled irrigation and drainage mode attained remarkable reduction of N and P losses,with a 16.7% reduction in total irrigation water,a 7.09% increase in rice yield,a 54% reduction in drainage water,a 38.07%、82.29% and 52.15% reduction of total NH+4-N,NO-3-N and TP losses respectively,compared with conventional irrigation and drainage mode.Efficient uses of water and nutrient were achieved under controlled irrigation and drainage mode.With reasonable water management,the key periods of N and P losing were controlled and N and P losses were significantly lowered in surface drain discharge from paddy field.
