摘　　要：在内蒙古土默川地区种植9个多花黑麦草品种,对其生产性能及营养品质进行测定,并采用灰色关联度法进行综合分析,结果表明:各参试品种在内蒙古土默川地区可刈割4茬,第2茬和第4茬生长速度较快,日均生长速度最快分别可达2.76 cm/d和2.92 cm/d;4茬鲜草产量在60156.67~113463.33 kg/hm^(2)之间,品种马克西姆的鲜草产量最高;品种邦德的粗蛋白质含量最高,为21.78%DM;品种剑宝的中性洗涤纤维含量最低,为53.20%DM。灰色关联度法综合分析结果显示,品种邦德、特高、马克西姆和海克里斯的综合性状表现较好,适宜在土默川地区推广种植。In this study,nine varieties of annual ryegrass(Lolium multiflorum Lam.)were planted in the Tumochuan area of Inner Mongolia,and their production performance and nutritive value were measured.The grey correlation method was used for comprehensive evaluate the determination indexes.The results showed that each tested variety could be cut for four times in the Tumochuan area.The growth rate of the second and fourth cutting was faster,with the fastest daily growth rate reaching 2.76 cm/d and 2.92 cm/d,respectively.The fresh grass yield of four cutting grass ranged from 60156.67 to 113463.33 kg/hm^(2),with variety Maximus having the highest fresh grass yield.The crude protein content of variety Abimdant was the highest,at 21.78%DM;the neutral detergent fiber content of variety Jumbo was the lowest,at 53.20%DM.The comprehensive analysis results of the grey correlation degree method showed that the comprehensive traits of the varieties Abundant,Tetragold,Maximus and Hercules perform well and are suitable for promotion and planting in Tumochuan area of Inner Mongolia.
