The invention discloses a method for raising earthworms in stages by using manure, which comprises the following steps of: S1, collecting raw materials, and carrying out classified collection treatment on four raw materials of pig manure, cow manure, sludge and straws; S2, treating base materials, measuring the carbon-nitrogen ratio of the raw materials, respectively adding the straws into the pigmanure, the cow manure and the sludge, and adjusting the carbon-nitrogen ratios of the pig manure, cow manure and sludge through the straws; S3, laying a base bed and inoculating the base bed with earthworms, paving the pig manure, cow manure, and sludge base materials prepared in step S2 on a flat ground, and inoculating the earthworms; step S4, preparing the mixed base materials, preparing a mixed base material a, a mixed base material b, a mixed base material c and a mixed base material d from the pig manure, cow manure and sludge base materials treated in step S2 according to a certain mass ratio; S5, feeding the earthworms, and adding different mixed base materials in different growth stages of the earthworms. The method solves the problems that one base material is adopted in the whole stage of earthworm culture in the prior art, the culture yield is low, and the treatment effect of the manure is not ideal.
