摘　　要：为研制一种可用于山体修复的功能土,达到生态循环修复的目的。去除过重金属的工业固体废弃物粉煤灰、气化炉渣为主体基质分别施加添加剂A、添加剂B进行种植燕麦草的盆栽实验,以及气化炉渣为主体基质分别种植多种植物进行筛选实验,通过测定最终功能土的理化性质及对应植物的相关农艺性状,探究不同因素对功能土的影响。结果表明,功能土的容重、pH值、电导率、有效磷、速效钾及植物的相关农艺性状均以添加剂含量不同而发生一定的变化,同时以气化炉渣为基质作为功能土时,三种植物(燕麦草、苏丹草、黑麦草)中种植燕麦草的优势要高于其他两种。本研究结果可为进一步研制生态循环修复的功能土提供理论依据。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.
