摘　　要：本试验以6份披碱草属牧草为研究对象,在新疆乌鲁木齐旱作条件下研究试验材料的生育期、牧草产量和牧草品质等农艺性状,筛选旱作条件下表现最好的牧草,以期为新疆地区的抗旱牧草品种的筛选和推广提供理论依据。结果表明,6个披碱草属牧草均能在新疆旱作条件下完成生育期,出苗整齐一致,并表现出较强的长势。老芒麦和披碱草的抗旱、抗寒能力较强,返青早,牧草产量高。其中,干草产量最高的是老芒麦,2017和2018年的干草产量分别为11 610.00 kg/hm^2和10 290.00 kg/hm^2,垂穗披碱草2017和2018年平均产量最低,为8 952.50 kg/hm^2。因此,在新疆天山地区旱作条件下最适宜种植的披碱草属牧草是老芒麦。Aiming at six varieties of Elymus,the paper studied the growth stage,grass yield,quality and other agronomic characters under dry-farming conditions in Xinjiang,and screened the best pasture to provide theory basis for screening and generalizing the drought-resistant varieties in Xinjiang.The results showed that all the six varieties could sprout and grow well and evenly as scheduled.While Elymus sibiricus L and Elymus dahuricus turcz showed the best drought and cold resistance ability.The yield of Elymus sibiricus L.was higher than other five varieties,which was 11 610.00 kg/hm2 and 10 290.00 kg/hm2 in 2017 and 2018 respectively.The average yield of Elymus nutans Griseb.was the lowest,which was 8 952.50 kg/hm2.So it is Elymus sibiricus L.that is the optimum for dry conditions in the northern slope of Tianshan in Xinjiang.
