摘　　要：本文旨在对红豆草在高寒牧区的物候期、产草量和营养成分进行评价研究,甘肃红豆草能够在海拔3000米左右的高寒牧区完成生育期,盛花期时株高达到最高。整个生长过程呈现出了慢-快-快-慢的生长趋势。盛花期时产量最高。影响红豆草品质的两个重要指标粗蛋白质和粗纤维,在不同刈割时期虽有小幅度变化,但是不同刈割时期的牧草均符合一级牧草标准。综合评价结果是高寒牧区红豆草盛花期是最佳利用期。The article analyzed the yield and nutrition in the different phenological phases of Onobrychis viciaefolia scop.cv.＂Gansu＂ in arctic-alpine area.The results showed that Onobrychis viciaefolia scop.cv.＂Gansu＂ could complete all the growth stages in arctic-alpine area at about 3000 m mountain altitude,and the height of Onobrychis viciaefolia scop.cv.＂Gansu＂ was the highest in the flowering.In the whole stage,the growth trends of Onobrychis viciaefolia scop.cv.＂Gansu＂ was slowness-rapidness-rapidness-slowness.When Onobrychis viciaefolia scop.cv.＂Gansu＂ was cutted in the flowering,the yield was the highest.The contents of CP and CF in forages changed according to the stages,but the quality of forages was good in all stages.The comprehensive evaluation results showed that flowering was the best utilizing period.
