Preparation method of artificial soil, artificial soil and application
By using high-temperature cell wall disruption degradation and co-assembly fermentation technology, and utilizing specific bacterial communities to secrete extracellular polymers at specific temperatures, the problem of bonding between loose organic matter and inorganic mineral particles is solved, forming water-stable large aggregates. This solves the problems of soil erosion and heavy metal pollution, and achieves efficient ecological restoration and landscaping applications.

Abstract
本发明涉及固体废弃物资源化利用与生态修复工程技术领域，具体涉及一种人工土壤的制备方法、人工土壤及应用。本发明提供的人工土壤的制备方法通过将半腐熟有机物与无机矿物进行原位共发酵，同时利用特异性菌群在特定温度下分泌海量胞外聚合物，实现了有机物与无机物的生物化学键合，构建出高度类似天然土壤的水稳性大团聚体。本发明提供的人工土壤中大于0.25mm的水稳性大团聚体的占比可达65%以上，呈现出高度类似天然壤土的物理结构，并且土壤中可生物利用态（酸可提取态）的重金属含量明显降低，极大降低了重金属的生物利用度和环境释放风险。
