摘要
为解决当前宁南半干旱区草畜产业发展中优质、高产牧草紧缺的问题,本试验利用灰色关联度法对2018—2019年16个饲用高粱(Sorghum bicolor(L.)Moench)品种的农艺性状、产量及营养价值进行了评价。结果表明:鲜干草产量表现最优品种是‘大龙’,中性洗涤纤维、酸性洗涤纤维、相对饲用价值表现最优品种是‘美洲巨人’、‘甘露400’,粗蛋白含量表现最优品种是‘绿巨人’,水溶性碳水化合物表现最优品种是‘海狮’。综合分析结果显示,‘大龙’、‘海狮’、‘大力士’、‘F10’、‘海牛’5个品种表现最优,适合在宁南半干旱区进行推广种植。
In order to solve the problem of high quality and high yield herbage shortage in the development of grass and livestock industry in the semiarid area of south Ningxia,the grey relational degree method was used to comprehensively evaluate the yield,nutritional value and agronomic traits of 16 forage sorghum varieties in 2018—2019.The results showed that the best variety of fresh hay was‘Dalong’.The neutral detergent fiber,the acid detergent fiber and the relative feeding value of the‘American Giant’and‘Manna 400’varieties were better than the control variety which was the Local Sorghum.Meanwhile,the highest crude protein content of variety was the‘Green Giant’,and the variety with the highest soluble carbohydrate content was‘Sea Lion’.The results of comprehensive analysis showed that the five varietie,‘Dalong’,‘Sea Lion’,‘Hercules’,‘F10’and‘Hainiu’were suitable for spreading and planting in the semiarid area of Southern Ningxia.
