【目的】揭示南方平原区水肥调控下的水稻节水减排效应。【方法】基于田间试验，设置传统淹灌（W0）和间歇灌溉（W1）2种灌溉模式，不施氮（N0）、减量施氮（N1，135 kg/hm2）及常规施氮（N2，180 kg/hm2）3种施氮水平，分析不同水肥调控方案下的水稻节水、增产、控污和减排效应。【结果】灌溉模式影响水稻灌水量、渗漏量和排水量，W1模式相比W0模式下的水稻灌水量减少18.12%~28.37%，渗漏量减少13.68%~22.85%，平均节水28.77%。在N1、N2施氮水平下，W1处理相比W0处理的水稻平均增产分别达到16.57%与29.94%。与W0模式相比，W1模式下的TN排放负荷量平均减少25.67%。同一灌溉模式下，TN排放负荷量随着施氮量的增加而增加。施氮水平对氨挥发总量有显...
