The invention discloses a method for improving washed soil, and relates to a method for improving soil. The method for improving washed soil comprises the following process: determining the proportion of sand granules of 0.025mm of washed soil according to a hydrometer method, when the proportion of sand granules greater than 0.025mm of the washed soil is 60%-80%, the additive amount of mushroom residue composite additives is 8wt%-10wt%; when the proportion of sand granules greater than 0.025mm of the washed soil is 40%-60%, the additive amount of mushroom residue composite additives is 3wt%-5wt%, and when the proportion of sand granules greater than 0.025mm of the washed soil is below 40%, the additive amount of mushroom residue composite additives is 1.5wt%-2.5wt%; and mushroom residue composite additive is formed by uniformly mixing mushroom residue after decomposition treatment, biogas residue and fulvic acid according to the mass ratio of 355:97:38. The method not only can be used for increasing the water retaining capacity of the washed soil, but also can replenish nutritional ingredients of the washed soil, meanwhile, is low in cost, has no engineering modification, and is high in feasibility in actual applications.
