于１９９６年在陕西省西临高速公路灞桥收费站对适应于陕西省高等级公路绿化的草种进行了研究。供试草种包括禾本科及豆科的１１个草种。经对各草种的密度、生长速度、盖度、颜色、绿期、地上生物量、地下生物量等生物性状指标进行测定分析。结果表明，除了白三叶和结缕草未能正常出苗或定植外，其它各草种均能正常生长，其中，禾本科的无芒雀麦、高羊茅、多年生黑麦草以及豆科的红豆草、小冠花，在各个时期的性状表现比较优良，可以作为陕西省高等级公路边坡绿化的应用草种。 In 1996, Shaanxi Province, west of the highway biaoqiao toll station to adapt to Shaanxi province highway greening grass species were studied. The test grasses include 11 grasses and legumes. The density, growth rate, cover, color, green period, aboveground biomass, underground biomass and other biological traits of each grass species were measured and analyzed. The results showed that except for the white clover and Zoysia could not normally germinate or colonize, all the other grasses could grow normally. Among them, the gramineous Bromus inermis, Tall Fescue, perennial ryegrass and leguminous red bean Grass, small crown flowers, traits in various periods of relatively good performance, can be used as high-grade highway in Shaanxi Province slope green grass application.
