在甘肃高寒阴湿区引进10种国外优良牧草,通过3年的生育期和产草量测定,结合抗病虫害能力、家畜适口性评估以及牧草营养成分的分析,筛选出适合该地区的优良牧草品种。结果表明,紫花苜蓿、苏丹草、俄菜抗病虫害能力较强,丰产性好,适口性佳,适宜在高寒阴湿地区推广。其中,俄菜年平均产量(干重)为69500 kg/hm2,粗蛋白含量为20.1%；紫花苜蓿年平均产鲜草产量折合干重为15500.0 kg/hm2,粗蛋白含量为18.6%；苏丹草年平均产鲜草产量折合干重为18800 kg/hm2,粗蛋白含量为14.8%。

For high quality forage production,10 forages were studied according to the local geographical conditions,,the data of growth period and yield,combined the ability of resistance diseases and pests and live-stock palatability and forage nutrients were used to evaluate the high quality forage spesies.The results showed that Medicago sativa L.,Sorghum sudanense (Piper)Stapf.and Symphytum officinale had a.higher resist-ance for diseases and pests,high yield and good palatability.Among three forages,the average annual dry matter yield and the content of crude protein of Symphytum officinale i were 69 500 kg/hm2 and 20.1%,repectively The average annual dry matter yield and the content of crude protein of medicago sativa L.were 15 500.0 kg/hm2 and 18.6%,repectively.The average annual dry matter yield and the content of crude protein of Sorghum sudanense (Piper)Stapf.were 18 800 kg/hm2 and 14.8%,repectively.
