Ash soil or humus soil from natural plants are used as a media for culturing carpet lawn and its production effect is better than that of pure soil significantly ( P <0 05) and the same as that of reported medium (sandy loam:wooden powder:cow dung:peat composed of rotten mosses=4∶3∶2∶1).
天然草皮烧成的火土或堆制成腐殖土用作培养基质生产地毯式草坪，其效果显著优于纯土壤的生产效果（Ｐ＜００５），与报导的培养基质（砂壤土∶锯末∶奶牛粪∶草碳＝４∶３∶２∶１）无差异（Ｐ＞００５）。
