摘要
为促进碳基材料在土壤改良与修复中的应用,从碳基材料的来源、理化特征和制备方式等3个方面进行了对比分析。粉煤灰和生物炭的理化性质更适宜在土壤改良和修复中应用,二者均能改善土壤理化性质,增强抗压强度,提高保水能力并间接影响土壤微生物。粉煤灰能够利用自身磁性提高土壤酶活性,而生物炭则以其独特的孔隙结构为微生物提供生长和繁殖的场所。
To promote the application of carbon-based materials in soil improvement and remediation,four kinds of carbon-based materials were analyzed and compared from their sources,physical and chemical characteristics and preparation methods.The results shows that fly ash and biochar performed better because they both improved the physicochemical properties,compressive strength and water holding capacity of soil,and influenced the microorganisms indirectly.Fly ash could enhance the enzyme activity of microorganisms with its magnetism.Biochar could provide special pore structure for microorganisms to grow and reproduce.
