摘　　要：在2012~2015年间,以国审品种"江夏""黔南"为对照,对"川西"扁穗雀麦新品系的物候期、生产性能以及主要的农艺性状等进行了品种比较试验。试验结果表明:"川西"扁穗雀麦品系3年平均鲜草产量为88 640kg/hm~2,高出"黔南" 11.07%,高出"江夏" 16.70%,高出原始群体9.01%;平均干草产量为11 060kg/hm~2,高出"黔南" 14.62%,高出"江夏" 19.50%,高出原始群体8.97%,鲜干草产量均比对照显著增加。"川西"扁穗雀麦新品系粗蛋白、粗脂肪、钙、磷均略高于"黔南"和"江夏"两个品种。酸性洗涤纤维略低于两个对照品种。总体而言,与对照品种相比,"川西"扁穗雀麦新品系植株高大,叶片含量丰富、适口性好、营养价值高。From 2012 to 2015,a variety comparative test was carried out on the phenological phase,production performance and main agronomic traits of the new strain of Bromus catharticus“Chuanxi”by comparing the national variety B.catharticus“Jiangxia”and B.catharticus“Qiannan”.The experimental results showed that the 3-year average fresh grass yield of“Chuanxi”strain was 88640kg/hm 2,11.07%higher than that of“Qianna”,16.70%higher than that of“Jiangxia”and 9.01%higher than that of the original population.The average hay yield was 11060kg/hm 2,which was 14.62%higher than that of“Qianna”,19.50%higher than that of“Jiangxia”,and 8.97%higher than that of the original population.The fresh and dry weight were significantly higher than that of the control group.The crude protein,crude fat,calcium and phosphorus of the new strain of“Chuanxi”were slightly higher than those in“Qiannan”and“Jiangxia”.Acid detergent fibers were slightly less than the two control varieties.In general,compared with the control varieties,the new“Chuanxi”were tall,rich in leaf content,good palatability and high nutritional value.
