摘　　要：试验以南疆阿拉尔地区种植的14种高粱属饲草为试验材料,通过测定高粱属饲草的产草量、粗蛋白(CP)、粗脂肪(EE)、酸性洗涤纤维(ADF)、中性洗涤纤维(NDF)、粗灰分(ash)和淀粉(strach)含量,采用灰色关联度进行综合分析。结果显示,14种高粱属饲草中,鲜草总产量为7.59×10^(4)~1.76×10^(5)kg/hm^(2),力神的鲜草产量最高;14种高粱属饲草中CP的含量为7.37%~7.64%,4264饲草品种最高;EE含量为4.13%~7.09%,绝佳EE含量最高;ADF含量为26.50%~33.48%,4264的ADF含量最低;NDF含量为50.30%~54.66%,标杆的ADF含量最低;ash的含量为4.94%~7.67%,5D61的ash含量最低;strach的含量为2.45%~3.17%,5D61的strach的含量最高。研究表明,力神、极光、SX19、冀草8号和大力士适宜在阿拉尔地区栽培种植。Fourteen sorghum forage varieties planted in Alar area of southern Xinjiang were used as experimental materials.The forage yield,crude protein(CP),crude fat(EE),acid detergent fiber(ADF),neutral detergent fiber(NDF),crude ash and starch content of sorghum forage were determined and comprehensively analyzed by grey correlation degree.The results showed that the total fresh yield was 7.59×10^(4)~1.76×10^(5) kg/hm^(2),and Lishen was the highest.The CP ranged from 7.37%to 7.64%,and 4264 was the highest.The EE ranged from 4.13%to 7.09%,and Juejia was the highest.The ADF ranged from 26.50%to 33.48%,and 4264 was the lowest.The NDF ranged from 50.30%to 54.66%,and Benchmarking was the lowest.The ash ranged from 4.94%to 7.67%,and 5D61 was the lowest.The strach ranged from 2.45%to 3.17%,and 5D61 was the highest.The experiment indicates that Lishen,Aurora,SX19,Jicao 8 and Hercules were suitable for cultivation in alar region.
