摘要
文章阐述了轻型基质的研究现状,利用菇渣、锯末、羊粪等常见废弃物配比成十种基质,对不同基质的容重、最大持水量、基质相对含水量;有机质、全磷、全氮、全钾等理化性质进行测定、对比和分析,发现4号基质具有容重小、保水性好,有机质含量高等特性,更加适用于北方屋顶绿化的生产实践。
The study summarizes the trends of roof green- base materials, and the 10 common formula lists of base materials using mushroom slag, saw dust, sheep manure, etc. Then it tests the physicochemical property of those base materials, including bulk specific gravity, largest water capacity, entire nitrogen, entire phosphorus, etc. All the 10 formula can support the plants well. Especially, No. 4 has advantages such as small bulk specific gravity, good water capacity and full of the organic matter, so it can be used in the north of China＇s production practice of roof greening.
