摘　　要：试验以9个不同饲用高粱属作物品种为研究对象,通过测定生育期、主要农艺性状、产量和营养成分,进行品种比较试验,确定供试品种在齐齐哈尔地区的适应能力。结果显示,供试品种的物候期均有差异,均未能完成完整的生育期。茎粗最大的供试品种为大力士(20.86 mm);干草产量最大的供试品种为12FS0018(33765.71 kg/hm^(2));粗蛋白含量最高的供试品种为大力士;酸性洗涤纤维含量最低的供试品种为龙甜1号,中性洗涤纤维含量最低的供试品种为12FS0018;相对饲喂价值最高的供试品种为龙甜1号,最低的供试品种为绿巨人;仅有供试品种牛魔王具有褐色中脉。研究表明,9个供试品种在齐齐哈尔均有一定的适应性,可根据不同的用途选择不同的栽培品种。The experiment based on nine different varieties of forage sorghum species,the fertility period,major agronomic traits,yield and nutrients were measured to determine the adaptability of the tested varieties in Qiqihar.The results showed that the phenological period of each variety was different,and the tested varieties failed to complete the whole growth period.The tested variety with the largest stem diameter was Dalishi(20.86 mm),the tested variety with the largest hay yield was 12FS0018(33765.71 kg/hm^(2)),the tested variety with the highest crude protein content was Dalishi,the tested varieties with the least acid detergent fiber content was Longtian No.1,the tested varieties with the least neutral detergent fiber content was 12FS0018,the highest relative feeding value was Longtan 1,and the lowest was Hulk.Only the tested variety Niumowang had brown midrib.The study indicates that the nine tested varieties have good adaptability in Qiqihar,and different purpose can be selected according to different production goals.
