摘　　要：为进一步评价川西短芒披碱草在大田生产条件下的生产性能,课题组于2015~2018年,以国审品种同德短芒披碱草为对照,分别在四川红原县、道孚县和青海海晏县开展了川西短芒披碱草多年多点的大田生产试验。连续3年的生产试验结果表明,川西短芒披碱草在各试验点生长良好,生产性能表现优良,综合评价优于对照品种同德短芒披碱草。川西短芒披碱平均鲜草产量为17760kg/hm^(2),较对照增产14.7%,增产显著;干草产量平均为6469kg/hm^(2),较对照增产13.2%,增产极显著。川西短芒披碱草较对照同德短芒披碱草具有突出的丰产性和一定的稳定性,在四川省阿坝州红原县、甘孜州道孚县和青海省海北州海晏县均能很好的适应,适宜在类似生态区推广种植。In order to further evaluate the production performance of Elymus breviaristatus Keng f.cv.Chuanxi under field production conditions,the research group conducted a multi-year field production test of“Chuanxi”in Hongyuan County,Daofu County,Sichuan Province,and Haiyan County,Qinghai Province from 2015 to 2018,with the national approved Elymus breviaristatus species“Tongde”as the control.The results of three consecutive years of production experiments showed that the plant had good growth and good performance in all test sites,and was superior to the control variety.The average yield of fresh grass was 17760kg/hm 2,which was 14.7%higher than that in the control.The average hay yield was 6469kg/hm 2,13.2%higher than that in the control.Compared with the control varieties,the Chuanxi has outstanding yield and stability,and can be well adapted to the Hongyuan,Daofu of Sichuan Province and Haiyan of Qinghai Province,so it is suitable for cultivation in similar ecological areas.
