| 中文摘要: |
| 为探讨不同节水灌溉模式的减排效果，在江西省灌溉试验中心站进行了两年的田间试验和测筒模拟试验，研究了淹水灌溉、间歇灌溉、蓄雨间歇灌溉3种节水灌溉模式对总氮、总磷和氮磷的减排效果.结果显示，与淹水灌溉和间歇灌溉相比，蓄雨间歇灌溉能够减少早稻排水量及排水次数分别为30%、3次，减少晚稻排水量及排水次数分别为100%、1次，减少氮磷排放量幅度分别为15%、35%左右，达到了减少排污的效果. |
| 英文摘要: |
| In order to explore the emission reduction effect under different water-saving irrigation modes， field experiments and barrel simulation experiments were conducted at Jiangxi irrigation test center station for two years.The reduction of total nitrogen，total phosphorus and nitrogen and phosphorus under three water-saving irrigation modes，i.e.，flooding irrigation mode，intermittent irrigation mode and intermittent rainfall storage irrigation mode was studied.Removal effect.The results showed that，compared with flooding irrigation and intermittent irrigation，the intermittent irrigation with rain storage could significantly reduce the drainage and drainage times of early rice by 30%and 3 times respectively，and the drainage and drainage times of late rice by 100%and 1 time respectively，so as to reduce the magnitude of nitrogen and phosphorus emissions of early and late rice 15%and 35%respectively，so as to achieve the effect of reducing sewage discharge. |
