在湖北省团林灌溉试验站开展试验，探讨不同水氮管理模式对水稻生理指标、产量及其构成及水分生产力的影响。结果表明，在适当的施氮量和追肥方式下，节水灌溉可明显提高水稻产量和水分生产率。最后提出了高产、节水、水分利用效率高的优化管理模式，并在江西省鹰潭市进行了有效试验。
An experiment was carried out in Tuanlin Irrigation Experiment Station, Hubei province, in order to investigate the effects of different water and nitrogen management patterns on the physiological indices, yield and its components, as well as water productivity in paddy rice. Results showed that under appropriate nitrogen supply quantity and top-dressing pattern, water saving irrigation can improve rice yield and water productivity evidently. Finally, an optimum management pattern for high yield, water saving, high water use efficiency is presented, and this pattern had been tested effectively in Yingtan City, Jiangxi province.
