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 Sorghum bicolor cultivated in Tongliao area, eight field sorghum varieties were compared in 2011, and the crude protein, neutral detergent fiber , Acid detergent fiber content, and fresh grass production, hay production, fresh ratio. The results showed that the quality traits of Hercules and Sweetgrass were better than those of the other six cultivars, and the differences among the cultivars reached the extremely significant level (P <0.01). The yield of Tongtian No.1 was the highest, while the quality was slightly lower than that of Hercules Sweet Graz, so Hercules, Sweet Graz suitable for green feed utilization, Tong sweet No. 1 suitable for silage use, these three varieties have promotion value in Tongliao area.
