粉煤灰和气化炉渣为基质探究其作为山体修复功能土的影响
Fly Ash and Gasifier Slag as Matrix to Explore their Influence as Functional Soil for Mountain Restoration
摘要
Abstract
In order to develop a functional soil that can be used for mountain restoration and achieve the purpose of ecological cycle restoration,the pot experiment of planting oat grass was carried out by using the industrial solid waste after removal of heavy metals-fly ash and gasification furnace slag as the main matrix and adding additive A and additive B respectively,and the screening experiment was carried out by planting a variety of plants with gasification furnace slag as the main matrix.By measuring the physical and chemical properties of the final functional soil and the relevant agronomic properties of the corresponding plants,the influence of different factors on the functional soil was investigated.The results showed that the bulk density,pH,electrical conductivity,available phosphorus,available potassium and related agronomic properties of plants of functional soil changed to a certain extent with the content of additives.At the same time,when gasification slag was used as the matrix of functional soil,the advantage of planting oat grass in the three plants(oat grass,Sudan grass and ryegrass)was higher than the other two.The results of this study can provide a theoretical basis for the further development of functional soil for ecological cycle restoration.关键词
