摘　　要：试验旨在评价夏播5个饲用甜高粱品种在西辽河平原灌区的生产性能。为筛选适宜西辽河平原灌区种植的饲用甜高粱品种,研究采用随机区组设计,测定5个饲用甜高粱(Sorghum saccharatum Moench)品种的农艺性状、产量和营养品质等指标,利用相关性、主成分和隶属函数分析综合评价5个饲用甜高粱品种的生产性能。结果显示,辽甜1号的茎粗、叶面积、鲜草产量显著高于晋牧1号、晋牧4号和通甜1号(P<0.05),与北甜C4差异不显著(P>0.05)。北甜C4的株高显著高于其他品种(P<0.05),辽甜1号的酸性洗涤纤维和中性洗涤纤维含量均显著低于北甜C4 (P<0.05),北甜C4的粗蛋白含量显著高于其他品种,为14.54%(P<0.05),晋牧1号、晋牧4号和辽甜1号的相对饲喂价值显著高于通甜1号和北甜C4 (P<0.05)。相关性分析表明,鲜草产量与茎粗呈显著正相关(P<0.05),中性洗涤纤维含量与株高呈极显著正相关(P<0.01)。将株高、茎粗等12个指标进行主成分分析转化为3个综合指标,累计贡献率达96.95%,基于主成分分析对参试品种进行隶属函数综合分析,得分从高到低依次为辽甜1号>北甜C4>通甜1号>晋牧4号>晋牧1号。研究表明,辽甜1号具有较高的饲草产量和饲草品质,适宜在西辽河平原灌区种植。The experiment was designed to evaluate the production performance of five Sorghumsaccharatum Moench varieties under summer planting in the irrigation area of West Liaohe Plain.In order to select suitable Sorghum saccharatumMoench varieties for planting in the irrigation area of the West Liaohe Plain,the study adopted a randomized block design to measure the agronomic traits,yield,and nutritional quality of five SorghumsaccharatumMoench varieties.The production performance of the five Sorghum saccharatum Moench varieties was comprehensively evaluated using correlation,principal component,and membership function analysis.The results showed that the stem diameter,leaf area,and fresh forage yield of Liaotian No.1 were significantly higher than those of Jinmu No.1,Jinmu No.4,and Tongtian No.1(P<0.05),and there was no significant difference compared with Beitian C4(P>0.05).The plant height of Beitian C4 was significantly higher than that of other varieties(P<0.05),and the concentrations of acid detergent fiber and neutral detergent fiber of Liaotian No.1 were both significantly lower than those of Beitian C4(P<0.05),the crude protein content of Beitian C4 was significantly higher than that of other varieties,at 14.54%(P<0.05),and the relative feeding value of Jinmu No.1,Jinmu No.4,and Liaotian No.1 was significantly higher than that of Tongtian No.1 and Beitian C4(P<0.05).Correlation analysis indicated that fresh forage yield was significantly positively correlated with stem diameter(P<0.05),and the content of neutral detergent fiber was extremely positively correlated with plant height(P<0.01).Twelve indicators,including plant height and stem diameter,were transformed into three comprehensive indicators through principal component analysis,with a cumulative contribution rate of 96.95%.Based on the principal component analysis,the membership function comprehensive analysis of the tested varieties showed that the scores from high to low were Liaotian No.1>Beitian C4>Tongtian No.1>Jinmu No.4>Jinmu No.1.The study showed
