| 摘 要： | 通过设立田间定位监测点，对高产水稻田的水及氮、磷的输入和排出进行了3年的定点监测，根据监测结果分析了稻田的氮、磷迁移特征和规律。结果表明，每667m^2稻田氮排出量约3000g，磷排出量约82g；随降雨及灌溉水带人的氮约1600g，磷约59g；两者相抵，表观净排出氮约为1400g，磷约23g。稻田氮、磷排出与稻田排水量及基面肥施用量有关。改进稻田氮肥施用时间和施用方法，合理管理稻田水量，减少排水，是减少高产水稻田氮、磷排放的关键技术措施。

| Abstract: | The import and export of water,nitrogen(N) and phosphorus(P) in high-yield paddyfield had been monitored,with field in-situ investigation,for three years.The characteristics and rules of N and P transport were analyzed according to the monitoring.The results showed that N and P export were 3 000 g and 82 g per 667 m2 respectively,and N and P imports from rainfall and irrigation were 1 600 g and 59 g per 667 m2.So the net exports of N and P from paddyfield were 1 400 g and 23 g per 667 m2 respectively.The ex... |
