轻型屋顶绿化人工基质配方的筛选

Study on Artificial Matrix of Saving Light Roof Greening

选取草炭土和建筑废料作为基质原料,设置了6个处理,同时选取田园土作为对照,通过对不同配方基质理化性质、基质失水率、植物生长量的测定,结合永久性萎蔫试验,对轻型屋顶绿化基质进行了研究。结果表明,90%草碳土∶10%碎砖块的配方适合作为轻型屋顶绿化景天属植物的基质配比。

Peatmoss and construction waste materials were selected as the raw material,6 treatments were set up,and rural soil was taken as a comparison.According to the tests on the basic physical and chemical properties of substrate,growth index and the rate of water loss,and combing tests of permanent wilting plants,it was found that 90% grassland substrate carbon： 10% broken roof tiles on the combination was more suitable as a light green Sedum plants substrate compositions.
