Method for rapidly propagating earthworms and producing high-quality earthworm manure by using solid-liquid separated cow dung and manure slurry

The invention provides a method for rapidly propagating earthworms and producing high-quality earthworm manure by using solid-liquid separated cow dung and manure slurry. The solid-liquid separated raw cow dung is used to establish an earthworm bed, and I completely irrigated with water before inoculation of earthworms, the manure slurry is poured to the surface of the culture bed in the breedingperiod to consume a waste liquid and increase the nutrition of the matrix, and an ecological refuge island for earthworms is established in a part of a fresh manure slurry-free area in the breeding period to make the earthworms gradually adapt to the manure slurry environment; and earthworm manure and earthworm cocoons are scraped and collected when the surface of the earthworm bed is taken by theearthworms and a large amount of the earthworm cocoons are distributed, earthworm larvae enter a lower layer and continuously produce cocoons, the collected earthworm cocoons and earthworm manure areused to cover a newly esta
