The invention discloses a preparation process for an environmentally-friendly soil remediation agent. The preparation process comprises the following steps: pulverizing; batching; one-stage fermentation; second-stage fermentation; production processing; and sieving and quality inspection. According to the invention, edible mushroom residues are used as a main raw material, and a series of production processing operation are carried out to complete the preparation of the environmentally-friendly soil remediation agent. The overall preparation process of the invention is simple and has low energy consumption; since the leftover edible mushroom residues used during production, the advantage of inclusion of a large number of nutrients in the mushroom residues is made full use of; and the product with great soil remediation effect can be prepared through scientific formulation. The soil remediation agent of the invention has remarkable soil remediation effect, is free of toxicity and secondary pollution, promotes
