摘　　要：[目的]筛选适合南疆气候土壤特性的饲用甜高粱品种。[方法]以8个甜高粱品种为试验材料,通过田间栽培试验对8个品种甜高粱的主要性状进行了比较分析。[结果]甜高粱M81的生物产量、株高、单株鲜重、分蘖数、茎节数、茎粗、叶长和叶宽最高,其次是丽欧和吉甜1号,LAMBAS和AS142较低;在成熟期丽欧和吉甜1号茎杆糖锤度最高,分别达到了23%和21%,其次是M81和新甜2号,糖锤度为19%和18%;延迟7～14 d收获可以明显提高甜高粱的糖含量。[结论]综合考虑8个供试甜高粱品种的主要性状表现,M81、吉甜1号和丽欧适应性较好,可以作为南疆饲用甜高粱品种进行利用。[Objective]To select cultivars of forage sweet sorghum suitable for climate and soil characteristics in southern Xinjiang.[Method]The major characters of eight sweet sorghum cultivars were compared through field cultivation experiments.[Result]M81 sweet sorghum was the largest in biological yield,plant height,fresh weight per plant,tiller number,stem node,stem diameter and leaf length,followed by Lio and Jitian 1.Lambas and As142 were relatively low.The sugar content of sweet sorghum could be improved significantly by delaying harvest for 7-14 d.[Conclusion]The cultivars M81,Jitian 1 and Lio could be used as the forage sweet sorghum cultivars in southern Xinjiang because of good comprehensive performances of main characters compared with the other sweet sorghum cultivars.
