通过３ 年牧草引种栽培试验，间比淘汰，优选出无芒雀麦、老芒麦、甘肃红豆草、甘农１号杂花苜蓿４种适应性极强的优良牧草。经对其产草量和营养价值进一步研究，结果表明，牧草的产量和营养价值逐年增高，生产性能稳定，第５ 年产草量达３ 万ｋｇ／ｈｍ ２，是高寒地区建立人工草地的优良牧草。 Through 3 years of introduction and cultivation of forage grass trial, the ratio out of phase, the preferred Brugouswreck, Elymus, Gansu sainfoway, Gannong 1 alfalfa alfalfa 4 extremely adaptable forage. The results of further study on the yield and nutritional value of herbage showed that the output and nutritional value of pasture increased year by year with stable production performance and the annual output of grass was 30,000 kg / hm 2 in the fifth year, which was the best for establishing artificial grassland in the alpine region grass.
