中文摘要	研究结果表明民勤荒漠绿洲边缘种植苜蓿年灌水4次,年灌水量3000m3/hm2,水效益5.087kg/m3,耗水系数由0.622m3/kgDM(春小麦)降为0.197m3/kgDM,比小麦、玉米节水3300～6300m3/hm2,水经济效益由1.02元/m3(玉米)、1.06元/m3(春小麦)提高到8.34元/m3,灌水成本比春小麦降低235元/hm2,光能利用效率由0.873%(春小麦)和1.040%(玉米)提高到1.44%,比小麦、玉米分别提高64.95%和38.46%.种植5年、7年苜蓿地0～30cm土层土壤有机质增加了26.36%和33.17%.
英文摘要	The study results show that in Minqin desert Oasia, the annual irrigation of alfalfa is 4 times, the irrigated norm is 3000m3/hm2 per year, the water benefit is 5. 087kg/m3 and the water consumption rate reduces from 0. 622m3/kg DM to 0.197m3/kg DM. Compared with the norm of wheat and corn,the irrigated norm of alfalfa reduces 3300～6300 m3/hm2, the irrigated cost reduces 235 yuan/hm2, the economic benefit of water enhances from 1.02 yuan/m3 and 1.06 yuan/m3 to 8.34 yuan/m3 and the radiation use efficiency enhances from 0. 873% and 1. 040% to 1. 44% per year, increasing by 64.95% and 38.46% .The soil organic matter increases by 26.36% and 33.17% with 5 years and 7 years alfalfa in 0～30cm soil.
