The invention discloses a method for improving soil by utilizing charcoal in cooperation with microbial carbonate mineralization bacteria. The invention belongs to the technical field of soil remediation, and particularly relates to a method for promoting mineralization and crystallization by using carbonate mineralizing bacteria, physically promoting generation of soil large aggregates, improving soil pores, chemically and continuously increasing the content of calcium carbonate in soil and improving fertility, and improving carbon-nitrogen ratio balance by using biochar. According to the method for improving the soil by utilizing the biochar and the microbial carbonate mineralizing bacteria, microbial communities can be reconstructed biologically, so that the planting capacity of microorganisms is improved, and the purpose of improving the soil is achieved. 本发明公开的一种利用生物炭协同微生物碳酸盐矿化菌改良土壤的方法。本发明属于土壤修复技术领域，具体是一种利用碳酸盐矿化菌加速矿化结晶，在物理上促进土壤大团聚体生成，改善土壤孔隙，化学上持续提升土壤碳酸钙含量和提升肥力，并使用生物炭改善碳氮比平衡；生物上可重新构建微生物群落，使微生物定植能力提升，从而达到改
