对5份新疆野生偃麦草(Er04、Er06、Er07、Er09、Er10)和5份引进的偃麦草(Er01、Er02、Er03、Er05、Er08)从生物学特性(生育期、形态特征)、坪用性(质地、盖度、颜色、均一性、绿色期等)及牧用性方面进行了研究。结果表明:供试材料在种内差异较大;Er04、Er07植株低矮、叶片较纤细柔软,坪用性好;Er05、Er10植株高大、叶片宽、叶量多、产草量高,牧用性好。通过聚类分析,初步将10份偃麦草分为3大类群,即草坪型(Er04、Er07)、草坪草牧草兼用型(Er01、Er02、Er03、Er06、Er08、Er09)和牧草型(Er05、Er10)。 The biological characteristics (growth period, morphological characteristics) of five wild Agropyron breviflora (Er04, Er06, Er07, Er09, Er10) and five introduced Erye, Er02, Er03, Er05 and Er08 Sex (texture, coverage, color, uniformity, green period, etc.) and animal husbandry. The results showed that: the tested materials differed greatly within the species; Er04 and Er07 plants were low, the leaves were thin and soft, and the plots were good. Er05 and Er10 plants were tall, leaves were wide, Good sex. According to the cluster analysis, 10 parts of Elytrigia elata were divided into three groups: Er04, Er07, Er01, Er02, Er03, Er06, Er08, Er09 and Er05, Er10).
