摘要
对2种种植基质及其不同厚度上5种屋顶绿化植物的生长状况进行调查,测定其成活率、株高、叶绿素含量、净光合速率等生长生理指标,进而比较其适应性。结果表明,泥炭、珍珠岩、蛭石、壤土以体积比为4:3:2:1的配比作为种植基质是比较适宜的。种植基质厚度为20～25cm时,即能满足植物生长发育的需要。5种屋顶绿化植物在2种种植基质内的适应性由高到低为:八宝景天>鸢尾>地被石竹>萱草>菊花。
With the development of urban construction,roof greening has become an important means in expanding spatial greening.In this paper,the growing conditions of several roof greening plants in two different thickness matrixes were studied and the physiological indices such as survival rate,plant height,chlorophyll content,and net photosynthetic rate and so on were examined.The results showed the complex matrix （sphagnum∶perlite∶vermiculite∶loam=4∶3∶2∶1） had optimum effect,besides,the matrix 20-25 cm thickness could meet the needs for plants growth and development.
