摘　　要：为筛选出适宜通辽地区种植的饲用高粱(Sorghum bicolor)品种,2011年对8个饲用高粱品种进行了田间比较试验,系统测定并分析了与动物生产性能相关的粗蛋白、中性洗涤纤维、酸性洗涤纤维的含量,及鲜草产量、干草产量、干鲜比。结果表明:大力士和甜格雷兹品质性状均优于其他6个品种,且品种间差异均达到极显著水平(P<0.01),通甜1号草产量最高,而品质略低于大力士和甜格雷兹,因此大力士、甜格雷兹适合作青饲利用,通甜1号适合作青贮利用,这3个品种在通辽地区均具有推广价值。In order to select the suitable forage sorghum varieties for planting in Tongliao,field comparisons of eight forge sorghum varieties were carried out in 2011.The characteristics including crude protein content,neuter detergent fiber content,acid detergent fiber content,fresh yield,dry yield,ratio of fresh matter to dry matter were tested.Results showed that both yield and nutritive quality of Strongman and Sweet were higher than that of the other varieties,and that there were significant differences among all tested varieties（P0.01）.Grass field of Tongtian 1 was the highest one.Crude protein content of Tongtian 1 was slightly lower than that of Strongman and Sweet.Therefore,Tongtian 1,Strongman and Sweet are worthy to be promotion.
