The invention discloses a hardening-resisting organic soil matrix and a preparation method thereof. The hardening-resisting organic soil matrix is prepared from the following raw materials: poultry manure, straws, sawdust, turfy soil, composite minerals, fine coal ash, zeolite powder, and a soil improver. The preparation method comprises the following steps: (1) mixing the poultry manure, the straws, the sawdust, the turfy soil and the composite minerals, transferring the mixture into a fermentation tank, adding water until the water content is 50 to 60 percent, then inoculating a fermentationagent, fermenting, drying a fermentation material, granulating to obtain granular fertilizer; and (2) mixing the fine coal ash, the zeolite powder and the soil improver, adding the granular fertilizer in step (1), mixing, stirring to obtain the hardening-resisting organic soil matrix. The hardening-resisting organic soil matrix prepared by the method is wide in source, low in cost, not only capable of promoting the plant growth, but also capable of significantly improving the hardening phenomenon of the soil, and capable of well protecting the soil.
