摘　　要：为了筛选出青海省较优的农作物秸秆品种,本试验对12种秸秆资源饲用品质指标进行测定,采用主成分分析法对不同品种秸秆的粗蛋白、粗脂肪、粗纤维、中性和酸性洗涤纤维、粗灰分、可溶性糖、钙和磷含量进行综合评价。结果表明:马铃薯秸秆粗蛋白含量最高,为9.72%,春小麦秸秆粗蛋白含量最低,为2.49%;青海扁茎早熟禾秸秆的粗脂肪含量显著高于其它秸秆;青海中华羊茅秸秆的中性洗涤纤维含量为44.89%,低于其它秸秆样品,而酸性洗涤纤维最高;燕麦秸秆的可溶性糖含量最高,达9.48%;蚕豆秸秆Ca含量最高,为10.41%。经综合评价得出结论,马铃薯秸秆营养品质评价结果最好,其次为青海扁茎早熟禾、青海冷地早熟禾和燕麦秸秆,以上秸秆资源具有一定的饲用价值,可作为饲料资源进行开发与利用。For the purpose of selecting superior varieties of major crop straws in Qinghai Province,this paper presents a comprehensive evaluation of the crude protein,crude fat,crude fibre,neutral and acid detergent fibre,crude ash,soluble sugar,calcium and phosphorus contents of different varieties of straws by measuring the forage quality indicators of 12 straw resources and using principal component analysis.The results showed that:potato straw had the highest crude protein content of 9.72%,and spring wheat straw had the lowest crude protein content of 2.49%;the crude fat content of Qinghai flat-stemmed early morning glory straw was significantly higher than that of the other straws;the neutral detergent fibre content of Qinghai Chinese fescue straw was 44.89%,which was lower than that of the other straw samples,and the acidic detergent fibre was the highest;the soluble sugar content of oat straw was the highest at 9.48%;broad bean straw had the highest Ca content of 10.41%.The comprehensive evaluation showed that the nutritional quality of potato straw was the best,followed by Qinghai flat-stemmed early morning glory,Qinghai cold-land early morning glory and oat straw,and the above straw resources had certain feeding value and could be developed and utilised as feed resources.
