通过微型蒸渗器和TDR土壤水分测定仪测定了不同地面节水灌溉技术条件下农田灌溉水消耗及水分利用效率，并结合气象数据比较不同灌水技术的优越性，测定了春玉米地土壤水分变化规律、玉米耗水规律、土面蒸发规律及水分利用效率，分析不同灌溉方式对春玉米水分利用效率的影响。研究结果表明，在石羊河流域中下游，玉米采用现有地面节水灌溉技术能有效地减少作物生育期耗水量，而全膜覆盖还可减少作物生育期的土壤蒸发量，提高农田的水分利用效率，不同节水技术可减少玉米耗水量80 m m以上，水分利用效率提高10．0％以上，在实际生产中可根据水源、基础设施、技术掌握难易程度、机械化程度等选择适宜春玉米的地面节水灌溉技术。

By using different water-saving irrigation technologies ,an experiment was conducted to determine irrigation water con‐sumption and water use efficiency in the growth period .Miniature micro-lysimeter and TDR soil moisture tester were used to meas‐ure farmland water consumption and water use efficiency ,which were used to compare the advantages of different ground water-sav‐ing irrigation technologies .The measured data were analyzed to learn the ground water-saving irrigation technology can effectively re‐duce crop water consumption in growth period .The film covers can still reduce soil evaporation capacity and improve water use effi‐ciency .Different ground water-saving technologies can reduce water consumption more than 80 mm and increase water use efficiency by more than 10 .0% .So we can choose suitable ground water-saving technology according to the source of water ,infrastructure , technology master degree of difficulty ,mechanization degree and so on of spring corn .
