[目的]研究屋顶绿化植物对废弃物转化基质的适应性.[方法]采用正交试验法,进行4因素3水平正交试验,以4种工农业废弃物粉煤灰、煤渣、秸秆和园林废弃物为基质,试验8种景天属植物的适应性情况.[结果]适宜屋顶绿化的废弃物转化基质配方为粉煤灰、煤渣、秸秆、园林废弃物,比例分别为1:1:1:1、1:2:2:2:2:1:2:1;8种景天属植物中佛甲草、垂盆草、宽叶佛甲草、德景天、费菜与八宝景天对废弃物转化基质适应性较强.[结论]废弃物转化基质应用于屋顶绿化中具有广阔的市场前景.%[ Objective ] To study the adaptability of roof greening plants in base materials transferred from waste. [ Method ] By applying the orthogonal test of 4 factors and 3 levels, 4 kinds of industrial and agricultural waste ( fly ash, slag, straw and waste of garden plants) are used to study the adaptability of 8 species of Sedum. [ Result] The proper volume ratio of fly ash, slag, straw and waste of garden plants for making suitable base materials were 1∶1∶ 1∶ 1, 1∶2∶ 2∶2 and 2∶ 1∶2∶ 1. Among the 8 test species, S. lineare, S. sarmentosum Bunge, S. hybridum Immergrunchett, S. aizoon and S. spectable Boreau are of higher adaptability to the base materials transferred from waste. [ Conclusion] The application of waste-transferred base materials enjoys a promising marketing future in roof greening.
