环保型发泡生态板在华南垂直绿化中的适配植物引种优选

Optimal Introduction of Plant Species Adapting to Eco-Friendly Foamed Ecological Boards for Vertical Greening in South China

摘要:

环保型发泡生态板是以建筑垃圾和粉煤灰为原料制作的模块化垂直绿化种植载体，绿色环保、质轻价廉，具有广阔的应用前景。为筛选适应发泡生态板碱性环境的垂直绿化植物，从滨海和石灰岩等地区引种61 种植物，对其在生态板栽培的存活率、越冬率、越夏率以及抗逆性、观赏性及生长势等指标进行观测评价。结果表明，引种植物存活49 种，适应生态板栽培、越冬率和越夏率在85% 及以上的有18 种。采用“百分法”综合筛选了12 种适用于发泡生态板的垂直绿化植物，其中紫背铺地锦竹草Callisia repens、秋红假紫万年青Belosynapsis ciliata和垂盆草Sedum sarmentosum 3 种植物综合得分大于80 分，可快速覆盖板体成坪。

Abstract:

Eco-frendly foamed ecological boards, made from construction waste and fly ash, offer a modular and low-cost solution for vertical greening. However, their alkaline nature poses challenges for plant survival. To identify suitable species, 61 plant varieties were introduced from coastal and limestone regions in South China and evaluated for survival rate, overwintering and oversummering performance, stress tolerance, ornamental value, and growth potential under board cultivation. Results showed 49 species survived, with 18 exhibiting overwintering and oversummering rates above 85%. Twelve varieties of vertical greening plants suitable for foaming ecological board were selected by percentage method', and Callisia repens, Belosynapsis ciliata , Sedum sarmentosum had a comprehensive score of more than 80 and could quickly cover 100% of the board body to form a lawn.
