摘要
以白榆为材料对屋顶绿化植物栽培基质进行筛选,结果表明:各处理间苗高、地径、冠幅、叶面积、生物量和根系数量存在一定差异。根据屋顶绿化植物栽培基质筛选标准,综合衡量各项生长指标及基质重量等因素分析,44.4%(体积百分比,后同)壤土+33.3%草炭土+蛭石22.2%较适宜。
Using Ulmus pumila as material, the cultivation matrix was selected for the roof greening plant in this paper. The results showed that plant height, diameter, crown width, leaf area, biomass and root amounts were different between all treatments. According to the standards of green roof plant cultivation matrix selection and index of plant growth and matrix weight, it was concluded that the media of 44.4% loam soil ＋ 33.3% peat soil ＋ 22.2% vermiculite was appropriate for the roof greening plant cultivation.
