NOVELTY - Aerobic composting method involves collecting cow manure, adding the collected manure into stacking tank, spreading the obtained mixture on the tank structure, inoculating earthworm on the tank, covering straws on surface of the stack and wetting the stack using water, collecting the stack sample, watering the collected sample for 2-3 times, nursing chickens in coop, or after the earthworms propagate to reach the pre-determined quantity, obtaining suitable quantity of propagated earthworms, and drying and crushing the obtained earthworms as fish feed.    USE - Aerobic composting method is useful for enhancing degradation of cow manure.    ADVANTAGE - The method improves composting effect. The raised earthworms can be fed to the chickens such as to form complete agricultural ecological chain.    DETAILED DESCRIPTION - Aerobic composting method involves collecting cow manure having a water content of 50-70% after performing fermentation, adding the collected manure into stacking tank, spreading the obtained mixture on the tank structure, inoculating earthworm on the tank, covering straws on surface of the stack and wetting the stack using water, collecting the stack sample, where the pH of growth of the earthworms are 6.5-8.5, watering the collected sample for 2-3 times, maintaining the water content of the sample to 60-70%, nursing chickens in coop, or after the earthworms propagate to reach the pre-determined quantity, obtaining suitable quantity of propagated earthworms, and drying and crushing the obtained earthworms as fish feed. An INDEPENDENT CLAIM is included for aerobic composting device, which comprises main structure chosen from tank structure (1), material feeding embedded plate (2), coop (3), sampling hole (4) and material inlet (5), where the tank structure comprises multiple sampling holes, baffle plate comprising multiple material feeding embedded plates, where the upper portion of the baffle plate in the main structure comprises coop, and the material inlet is located on the coop on the upside of the main structure.    DESCRIPTION OF DRAWING(S) - The drawing shows perspective view of aerobic composting device.    Tank structure (1)    Material feeding embedded plate (2)    Coop (3)    Sampling hole (4)    Material inlet (5)
