中文摘要	通过对民勤绿洲白然、社会、经济现状的分析评价，引进并筛选出了适应性强、光能利用率和产草量高、营养全面、饲用价值高、适宜河西荒漠绿洲区栽培的兰热莱恩德(Ranger Lander)、凯恩(Kane)、新疆和田大叶3个紫花苜蓿(Medicago sativa)品种。在民勤绿洲灌溉条件下，年刈割4茬，年灌水3 000 m。／hm。，种植第3年分别取得18 793，12 953，14 688 kg／hm。的干草产量和3 535，2 474，3 114 kg／hm。的粗蛋白产量I光能利用率达1．77％，1．22％，1．38％。并组建草畜产业生产基地，进行了苜蓿人工草地建植、节水丰产栽培、产业化生产、改良土壤、培肥地力及种草养畜的配套技术研究、示范与推广。形成了以苜蓿草粉、苜蓿干草等草产品和小尾寒羊种羊及肥羔生产为格局的草畜产业，实现了苜蓿和家畜生产2个"s"型生长曲线的高效耦合，建立了干旱荒漠区特有的草地农业发展模式。指出只有建立草地农业系统，发展以苜蓿产业为主的节水型现代草地农业，才是干旱荒漠区可持续发展的关键。
英文摘要	Based on analysis and evaluation of the current natural , social and economic situations in the Minqin desert oasis, 8 alfalfa {Medicago sativa) varieties were introduced, including Ranger Lander, Kane and Xinjiang alfalfa. These three varieties were selected, having strong adaptability, high use efficiency of light radiation , high yield, comprehensive nutrition, high feed value, and suitability for cultivation in the Hexi desert oa sis region. In the Minqin oasis, having cut 4 times in the third year after establishment, irrigated at 3 000 m3/ hm2, hay yields were 18 793,12 953, and 14 688 kg/hm2, and crude protein (CP) yields were 3 535, 2 474, and 3 114 kg/hm2, for these three varieties respectively. Use efficiency of light radiation was 1. 77%, 1. 22%, and 1.38%, respectively. A production base for the forage livestock industry was established, and research, demonstration and extension carried out on establishing alfalfa pasture, high yielding water efficient cultiva tion , industrialized production, improving soil moisture and conditions, and forage growing and raising live stock. A structured forage livestock industry was formed combining goods including alfalfa meal and hay, and fat-lamb production using small-tailed han sheep tupping rams, realizing highly efficient coupling of the alfalfa and livestock production "S" shaped logistic curves, establishing a particular pastoral agriculture development pattern for desert regions. Developing pastoral agriculture with water-economising alfalfa is key to sustainable development in the Hexi desert oasis region.
