摘　　要：隔沟灌溉技术是一项新型的节水灌溉技术,在国内外都已进行了较长时间的研究和推广,但在宁南山区尚没有推广应用的报道。2004年“北方半干旱集雨补灌旱作区(宁夏彭阳)节水农业技术体系集成与示范”课题引进该项技术,在宁夏彭阳王洼示范区进行了地膜玉米隔沟灌试验研究。结果表明,隔沟灌与全灌相比,产量相近,水分利用效率增加了12.44%,但用水量只有全灌的一半;与不灌溉相比,经济产量和水分利用效率分别增加了38.24%和38.65%。The separate furrow irrigation is a new way of economizing irrigation, which has been investigated and popularized,but there is no report in southern Ningxia hill region. In Pengyang county, separate furrow irrigation of film maize was introduced. The result indicats：separate furrow irrigation is compared with full irrigation, the output is equal, water use efficiency add by 12.44%, using water quantity is half to full irrigation; compared with no irrigation,economic output and water use efficiency is increased 38.24% and 38.65% respectively.
