| 摘 要： | 对甘南玛曲七种主要饲草的干草产量、高度、常规养分(粗蛋白质、酸性洗涤纤维、粗脂肪、粗灰分、无氮浸出物、钙、磷)进行测定,用灰色关联度法对其营养价值进行评价.结果表明:天然草地干草产量为2882kg/hm2,比新疆大叶苜蓿、甘农l号苜蓿、红豆草和箭(苫)豌豆高,比绿麦、燕麦和垂穗披碱草低,牧草营养价值为甘农1号苜蓿＞绿麦＞箭(苫)豌豆＞垂穗披碱草＞新疆大叶苜蓿＞燕麦＞天然草地＞红豆草.

| Abstract: | The yield,height and nutrients(including CP,CF,EE,CA,NFE,Ca,P) of seven forage species in Maqu county were measured,and their nutritional values were evaluated by the grey correlation method.The results showed that the hay yield in the natural grassland was 2882kg/hm2,which was lower than Secale cereale L,Avena sativa L.and Elymus nutans Griseb,but it was higher than Medicago sativa L.cv.Xinjiang daye,Medicago sativa L.cv.Gannong No.1,Vicia sativa L.The order of nutritional values of the herbages was Medicago sativa L.cv.Gannong No.1>Secale cereale L.>Vicia sativa L.>Elymus nutans Griseb>Medicago sativa L.cv.Xinjiang daye>Avena sativa L.>nature grassland>Onobrychis viciaefolia Scop. |
