| 摘 要： | 根据湖北省团林灌溉试验站水稻水肥耦合试验资料，分析了不同水肥处理对水稻生长发育，水稻产量及其构成，水稻水分生产率等的影响规律。结果表明，在适当的施肥量和合理的追肥方式下，与传统的淹灌相比，节水灌溉有显著的节水增产效果，提高了水分生产率。通过分析的数据提出了一种高效利用水肥的稻田管理模式，并将该管理模式在江西鹰潭进行了示范。

| Abstract: | 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. |
