| 摘 要： |
佛甲草（Sedum lineare）因繁殖能力强，具有较强的耐热、耐旱性，且易于管理，目前在屋顶绿化中被广泛应用。然而工程实践表明,佛甲草不耐水涝，尤其在高温高湿条件下容易因根茎腐烂而死亡。本研究从基质角度出发，选用了进口泥炭、国产泥炭、国产草炭、园林废弃物、珍珠岩、椰丝等为基质材料，通过分析佛甲草相关生长指标以及混合基质的理化性质等，筛选出在高温高湿条件下最适合佛甲草生长的基质配方。结果表明,高温高湿条件下佛甲草最适合在园林废弃物中生长，且价格最低，可节约工程成本；进一步通过正交试验得出园林废弃物∶珍珠岩∶椰丝=8∶1∶3和8∶3∶2时，佛甲草生长最好，为佛甲草高温高湿条件下生长的最佳基质配比。

| Abstract: | Sedum lineare is a popular choice among green roofing projects due to its extensive management, easy propagation and tolerance for heat and drought adaptability. However, the project practice shows that Sedum lineare cannot resist water logging, it even leads to root rot and death in tropic and humid environmental conditions. The test is adopted to screen the substrates of S.lineare for the green roofs with the import peat, domestic peat, green waste, perlite and palm fiber. Based on the growth index of S.lineare and the physicochemical property of the substrates, the test aims to screen which is the most suitable substrate for S.lineare. The result shows that the green waste is the best suitable substrate for S.lineare in tropic and humid conditions, and it is the cheapest one to save engineering cost. Furthermore, an orthogonal experiment is adopted to find green waste∶perlite∶Palm fiber is 8∶1∶3 and 8∶3∶2 and both have a remarkable effect on S.lineare growth. |
