摘　　要：为丰富宁夏引黄灌区牧草种质资源,于2017年4–10月在宁夏引黄灌区采用随机区组试验设计对10个高粱(Sorghum bicolor)品种进行适应性评价,通过测定农艺性状、营养成分和抗倒伏系数等指标,对抗倒伏系数的各因子间进行相关分析、营养成分指标间进行主成分分析后对不同品种的营养价值进行得分排序,采用隶属函数对10个高粱属品种进行综合评价。结果表明,10个高粱品种在该地区的生育期为113～125 d,以绿巨人品种株高最高,达312.67 cm,干草产量最高的品种为海牛(29.72 t·hm–2),且高于其他品种(P <0.05),大力士的茎秆糖锤度最高,为16.37%,叶绿素含量在26.97～51.95(SPAD),相对牧草质量最高的品种为大奖2120(154.33),营养价值综合评价得分前五的品种为大奖2180>斯威特>大奖2120>金冠>绿巨人。抗倒伏较强的5个品种依次为大力士、大奖2180、海牛、绿巨人和大奖2120。最终根据营养成分、干草产量和抗倒伏系数综合评价得出,大奖2180、大力士、绿巨人、海牛和大奖2120适合在宁夏引黄灌区引种栽培。To enrich the forage germplasm resources of the irrigated area in Ningxia, a randomized block design was adopted to study the adaptability of ten Sorghum varieties from April to October 2017. The study examined the agronomic traits, nutritional value, and the anti-lodging coefficient. An analysis of the correlation between the various indicators of the antilodging coefficient, principal component analysis among the nutrition indexes, and the comprehensive score of nutritional content was conducted. The subordinate function was conducted to evaluate the different sorghum varieties. The results showed that the ten sorghum varieties had a growing period of 113~125 days, the tallest variety was Lvjuren (312.67 cm), the highest hay yield was from Hainiu (29.72 t·ha^–1), and there were significant differences among the varieties (P < 0.05). The longest stem Brix was Dalishi (16.37%), the range of chlorophyll content was from 26.97~51.95 (SPAD), the highest quality forage variety was from Dajiang 2120, which is 154.33, and the top 5 varieties from the comprehensive evaluation of nutritional content scores were: Dajiang 2180 >Siweite > Dajiang 2120 > Jinguan > Lvjuren. The top 5 varieties regarding the coefficient of lodging resistance were Dalishi, Dajiang 2180, Hainiu, Lvjuren, and Dajiang 2120. Dajiang 2180, Dalishi, Lvjuren, Hainiu, and Dajiang 2120 were widely popularized and cultivated in the irrigation area in Ningxia, based on the comprehensive evaluation of nutritional content, hay, and the anti-lodging coefficient.
