摘　　要：为筛选适宜半干旱区种植的饲用燕麦(Avena sative)品种,本研究采用田间随机区组设计,于2020年在国家牧草产业技术体系赤峰试验站种植10个燕麦品种,测定其乳熟期的农艺性状和营养品质指标,并采用灰色关联度评价方法综合评价。结果表明:1)燕麦品种的株高为61.10~121.76 cm,鲜草产量为15 757.87~37 685.50 kg·hm^(-2),干草产量为3 443.67~6 425.91 kg·hm^(-2),在内蒙古赤峰地区,10个燕麦品种中鲜草产量最高的是‘甜燕1号’,干草产量最高的是‘白燕3号’。2)不同燕麦品种粗蛋白、中性洗涤纤维、酸性洗涤纤维含量变化分别为11.75%~15.45%、50.69%~53.42%和26.82%~32.65%,‘青海甜燕麦’和‘甜燕1号’达到特级干草标准。灰色关联度综合评价结果表明,‘青海甜燕麦’和‘甜燕1号’是表现最好的两个品种,且适合在内蒙古赤峰地区推广种植。Our study aimed to identify the oat(Avena sative)varieties that are suitable for Chifeng,which is a semiarid area.We planted 10 oat varieties in a random block design at the National Forage Industry System Experimental Station in Chifeng.We harvested the oat plants at the milk-ripening stage.We analyzed the agronomic traits and quality index of these 10 oat varieties and compared their growth performance and forage yield,and quality through grey correlation degree analysis.The following results were obtained:1)Among the 10 Oat varieties in Chifeng region of Inner Mongolia,the ranges of plant height,fresh grass yield,and hay yield were 61.10~121.76 cm,15757.87~37685.50 kg·ha^(-1),and 3443.67~6425.91 kg·ha^(-1),‘Tianyan No.1’had the highest yield of fresh grass,and‘Baiyan No.3’had the highest yield of hay.2)The ranges of contents of crude protein,Neutral detergent fiber,and acid detergent fiber among the different varieties were 11.75%~15.45%,50.69%~53.42%,and 26.82%~32.65%,‘Qinghai Sweet oat’and‘Tianyan No.1’meet the special grade hay standard.respectively.The grey relational analysis results showed that‘Qinghai Sweet oat’and‘Tianyan No.1’are suitable for planting and popularization in the Chifeng area.
