哈尔滨市三种冷季型草坪草滞尘能力的研究

草坪草作为城市绿化的构建材料,不仅在美化环境方面具有极高的应用价值,在改善城市生态环境方面也挥着重要的作用。以哈尔滨市道路绿化常用草种中的草地早熟禾、多年生黑麦草和紫羊茅为对象,对3种草种叶面解剖结构和滞尘能力进行测定,通过比较分析,发现不同草种间的滞尘能力与叶面结构形态的关系密切;在相同种植密度和面积的草坪上,滞尘量由高到低依次是多年生黑麦草、紫羊茅、草地早熟禾;滞尘量随时间增加呈现有限增长的趋势。

Research on the Dust Control Ability of Three Kinds of Cold Season Turf Grass in Harbin City

Turf grass,as one of the building materials in urban greening,not only has a high value in landscaping,but also plays an important role in improving the urban ecological environment.Taking the turf grasses of kentucky bluegrass,perennial ryegrass and red fescue that were commonly used in road greening in Harbin city as the research objects,leaf anatomy and dust control ability of the three kinds of grass were tested.Through comparative analysis,it is found that the dust control ability of different grasses has a close relationship with leaf morphology.Under the same conditions of area and planting density,the ranking of dust control ability from high to low level is relatively perennial ryegrass,red fescue and kentucky bluegrass.And the controlling quantity shows a limited growth trend as the time increases.
