摘　　要：针对辽西地区水资源极度匮乏、现有的农业灌溉体系不完善、农业生产水平低下等问题,从提高机井利用率和水土资源的使用效率入手,通过对17种农业节水技术的集成应用研究,提出了适合辽宁西部地区的4种特色农业节水模式,平均节水1156.5 m3/hm2,增收4657.5元/hm2。可为国内同类地区发展现代农业提供借鉴。Aiming at the actuality of water resource scarcity and farming irrigation system faultiness and agricuhure technique level lowness in west areas of Liaoning province, we studied the increase of water resource efficiency and pump-well irrigation efficiency. 17 kinds of water-saving techniques were integrated and 4 kinds of farmland water-saving modes were brought out. The result showed that the irrigation amount can reduce to 1156.5 m^3/hm^2 ,and the income can increase to 4657.5 yuan/hm^2. These water-saving modes can provide reference to the same areas.
