摘　　要：为解决我国乌蒙山区冬闲田闲置、土地利用率低的问题,以19份燕麦(Avena sativa)品种为研究对象,开展品种生产性能和营养品质综合评价试验,通过灰色关联度综合评价,筛选出适宜在乌蒙山区冬闲田推广种植的优质燕麦品种。结果表明:在相对干旱的年份,干草产量排在前3名的品种是‘伽利略’、‘青引1号’和‘青海444’,分别为15941.55、15744.67和13831.14 kg·hm^(-2);营养品质方面,19份燕麦品种中,粗蛋白含量排名靠前的品种是‘贝勒Ⅱ’和‘青引1号’,并且二者中性洗涤纤维和酸性洗涤纤维含量均处于较低水平;相对饲喂价值较高的品种分别是‘贝勒Ⅱ’、‘贝勒’、‘林纳’和‘青引1号’;灰色关联综合评价结果显示,‘青引1号’、‘伽利略’和‘青海444’排名靠前,综合生产性能表现较好,可以作为乌蒙山区冬闲田的主推品种进行种植。To solve the problems of idle land and the low land use rate in winter fallow fields in the Wumeng Mountain area of China,19 oat varieties(Avena sativa)were used as research objects to conduct detailed evaluation tests on production performance and the nutritional quality of varieties.Through detailed evaluation of the grey correlation degree,high quality oat varieties suitable for promotion and planting in winter fallow fields in the Wumeng Mountain area were selected.The results showed that in the relative drought years,the top three hay grass yield of the 19 oat varieties was‘Jialilüe’,‘Qingyin No.1’and‘Qinghai 444’,with 15941.55,15744.67 and 13831.14 kg·ha-1,respectively.In terms of nutritional quality,among the 19 oat varieties,the top varieties for crude protein content were‘Baler Ⅱ’and‘Qingyin No.1’.Neutral detergent fiber and acid detergent fiber were at low levels,and neutral detergent fiber and acid detergent fiber were at a low level.The varieties found to have better relative feed value were‘Baler Ⅱ’,‘Baler’,‘Lena’,and‘Qingyin No.1’,respectively,after applying gray correlation.The detailed evaluation results showed that‘Qingyin No.1’,‘Jialilüe’,and‘Qinghai 444’,with high weighted correlation ranking and high overall production performance,could be planted as the main varieties in winter fields in the Wumeng Mountains.
