     摘要:对降低多孔混凝土砖基架的pH值、EC值的方式进行了筛选研究,并配置抗逆性强的地被植物,优化施工方法,研制出可以应用于立体绿化墙面和屋面绿化施工用的植被砖,为立体绿化提供一种方便、快捷、低成本的施工方式。结果表明:通过浸泡水洗的方法可以达到降低多孔混凝土pH值和EC值的效果。2%挪威复合肥溶液作为多孔混凝土降碱的调节剂最为合适。4种常见地被植物中,高羊茅的长势较好。

    Abstract:The study has a research on lower the pH and EC of porous concrete brick,and configures the strong resistance plants in order to manufacture a prefabricated stereo greening vegetation brick for wall side and roof greening. This provides a convenient,low cost construction method for stereo greening. Results show that:the pH and EC values of porous concrete could be lowered by soaking water. The effect of 2% Norwegian fertilizer solution to lower the pH value is most suitable. Among the four common ground-covering plants,Festuca elata showed the best growth trend.
