摘　　要：对来自加拿大的5个禾本科牧草品种在河西走廊荒漠绿洲边缘区进行了3年引种栽培试验,结果表明:Largo、Dahurian和Haymaker 3个品种具有干草产量高和生态适应性强的特点,在种植第2年干草产量分别为13.1t/hm2、12.8t/hm2和12.3t/hm2,但Largo干草质量相对较差。Signal和Adanac具有较强的抗旱、抗寒性和抗病虫能力,且Adanac具有较强的耐盐碱能力,但产草量低于Largo、Haymaker和Dahurian。品种Haymaker和Dahurian的种子产量较高,种植第2年种子产量分别为998kg/hm2和1020kg/hm2,而Largo的种子产量相对较低。总体评价认为,Haymaker、Dahurian、Signal和Adanac在河西干旱荒漠区及同类地区具有广泛的推广和应用价值。Five varieties of Gramineous pastures were introduced from Canada and cultivated for three years in the edge of a desert oasis of Hexi Corridor. The results showed that Largo, Dahurian, and Haymaker had the characteristics of high hay yield and good ecological adaptability, hay yield reached 13.1 t/hm^2 , 12.8t/hm^2 , and 12.3t/hm^2 in the second year, respectively, but the Largo was relatively poor in quality of hay; hay yield of Signal and Adanae was lower than Largo, Haymaker and Dahurian, but had strong drought-resistance, cold-resistance and pest resistance, and Adanac was highly salinity tolerance at the same time; Haymaker and Dahurian were high in seed yield, the seed yield reached 998kg/hm^2 and 1020kg/hm^2 in the second year after planting, respectively, but seed yield of Largo was relatively low. Haymaker, Dahurian, Signal and Adanac had extension and application value in arid desert area of Hexi and similar areas.
