摘　　要：为筛选出适合在宁夏引黄灌区推广应用的饲用高粱(Sorghum bicolor(L.) Moench)品种,本试验利用灰色关联理论对6个高粱品种的7个生长指标和6个营养指标进行综合评价。结果表明:生长特性上大奖2180抗倒伏能力较强,海牛和丰甜在株高、茎粗、鲜重和干重要优于其他品种;营养成分上大奖2180的粗蛋白和粗脂肪含量、丰甜和大奖2180的酸性洗涤纤维和木质素含量、海牛的粗灰分含量要优于其他品种。应用灰色关联度理论对6个高梁品种进行综合评价得出,丰甜、大奖2180和海牛较其他品种更适宜在宁夏引黄灌区推广应用。In order to screen sorghum varieties suitable for spreading and application in ningxia.The seven growth indexes and six nutrition indexes of six sorghum varieties were comprehensively evaluated by using the grey relational degree.The results showed that dajiang 2180 have strong lodging resistance in growth characteristics.Hainiu and fengtian were superior to other varieties in plant height,stem diameter,fresh weight and dry. The crude protein and fat content of dajiang 2180,the acid washing fiber and lignin content of fengtian and dajiang 2180,and the crude ash content of hainiu are better than other breeds in terms of nutritional indicators.Comprehensive evaluation of six sorghum varieties using grey relational degree can reveal,Fengtian,Dajiang 2180 and Hainiu are more suitable for promotion and application in ningxia irrigation area.
