摘  要：
针对湖北省鄂北地区干旱现状,采用长渠灌溉试验站2009—2013年的水稻灌溉试验资料,研究了不同节水灌溉模式下水稻需水变化规律和生长特性。结果表明,灌溉模式对水稻蒸发蒸腾量、耗水量、灌水量、产量及水分生产率等指标有显著影响。与浅灌模式和中蓄模式相比,湿润模式水稻耗水量和灌水量明显降低,同时提高了水稻产量和水分生产率。因此,从节水和增产角度,湿润模式是较为适宜的节水灌溉模式。

摘  要：
Aiming at the water shortage of northern Hubei province,the rice evapotranspiration and growth characteristics under different water saving irrigation models were studied based on the experimental results of latest five years in Changqu experimental irrigation station.The results showed that rice evapotranspiration,water consumption,irrigation water,yield and water productivity were significantly influenced by irrigation model.Compared with shallow irrigation model and storage irrigation model,the rice water consumption and irrigation water were reduced obviously under wet irrigation model condition,simultaneously,the rice yield and the water productivitywere increased.From the point of water saving and increase production,the wet irrigation model is an appropriate water saving irrigation model.
