摘　　要：人工草地是解决草地畜牧业冬春季节草畜供求矛盾的有效途径。通过３年（１９９３～１９９５年）牧草引种栽培试验，对优选出的４种牧草无芒雀麦（Ｂｒｏｍｕｓｉｎｅｒｍｉｓ）、老芒麦（Ｅｌｙｍｕｓｓｉｂｉｒｉｃｕｓ）、甘肃红豆草（ＯｎｏｂｒｙｃｈｉｓＵｉｃｉｃａｅｆｏｌｉａｃｖ，Ｇａｎｓｕ）、甘农１号杂花苜蓿（Ｍｅｄｉｃａｇｏ．ｖａｒｉａｃｖＧａｎｎｏｎｇＮｏ．１）的产草量和营养价值进行研究。结果表明：牧草的产草量和营养价值逐年增高，第３年产草量达到３００００ｋｇ／ｈｍ２，是高寒地区建立人工草地的优良牧草。Cultivating grass is a effective means to solve the Problem that there is not enough food for animal in winter spring season.The yields and nutritive values of four forages (Bromus inermis Elymus sibiricusvar Onobrychis Uiciaefolia cv.Gansu M.varia cv Gannong No.1) wich were selected in a three-year introduction experience were measured.The result showed that the yield and nutritive value were arised year after year,the yield reached 30,000kg/hm 2 in third year .And the forages were well adapted to the plateau area \ \
