为筛选出川西北高原适宜种植的优良燕麦(Avena sativa L.)品种,本研究对国内外7 个燕麦品种的生育期、产量性状、农艺性状和营养品质进行了两年的调查、分析和比较,并采用灰色关联法进行综合评价.结果表明,7 个参试燕麦品种均能在红原县顺利完成生长发育,'阿坝'生育期最短,只有 120d;'美达'生育期最长,达 146d.各燕麦品种的鲜草产量为17 749.59~38 175.35kg/hm2,干草产量为4990.88~9230.26kg/hm2,种子产量为1242.77~2453.96kg/hm2,其中'牧丰'的鲜草产量和干草产量均最高,'泰森'的种子产量最高.各参试燕麦品种粗蛋白含量为8.69%~12.34%,'梦龙'最高,'牧乐思'其次;'牧丰'与'美达'的酸性洗涤纤维和中性洗涤纤维含量处于中等水平,但优于对照品种'阿坝'.灰色关联分析结果表明,加权关联度从高到低依次为:'牧丰'>'美达'>'牧乐思'>'梦龙'>'泰森'>'海威'>'阿坝',表明'牧丰'与'美达'的综合性能表现最佳,适宜在川西北高原地区种植.
Comprehensive evaluation of the production performance of 7 oat varieties in the Northwest Plateau of Sichuan
In order to screen high-quality oat(Avena sativa L.)varieties suitable for planting in the Northwest Plateau of Sichuan,the growth period,yield traits,agronomic traits and nutritional quality of seven oat varieties at home and abroad were investigated,analyzed and compared for two years,and the grey correlation method was used for comprehensive evaluation.The results showed that all the seven tested oat varieties could grow successfully in Hongyuan County,and the growth period of'Aba'was the shortest,only 120 days.The growth period of'monida'was the longest,up to 146 days.The fresh yield of oat varieties was 17 749.59~38 175.35kg/hm2,the hay yield of oat varieties was 4 990.88~9 230.26kg/hm2,and the seed yield of oat varieties was 1 242.777~2 453.96kg/hm2,among which the fresh yield and hay yield of'Mufeng'were the highest,and the seed yield of'Taisen'was the highest.The crude protein content of oat varieties was 8.69%~12.34%.The contents of acid detergent fiber and neutral detergent fiber of'Mufeng'and'monida'were at medium level,but better than the control variety'Aba'.The results of grey correlation analysis showed that the weighted correla-tion degree from high to low was:'Mufeng'>'monida'>'Molasses'>'Magnum'>'Taisen>'Haiwee'>'Aba',indi-cating that'Mufeng'and'monida'have the best comprehensive performance,which are suitable for planting in Northwest Plateau of Si-chuan.
