The invention relates to the technical field of fertilizer production, in particular to a method for preparing a bio-organic fertilizer by resource utilization of earthworm feces. The microbial fertilizer liquid contains rich bacillus licheniformis, and the bacillus licheniformis and the potassium humate cooperate with each other, so that the absorption of crops on nitrogen, phosphorus and potassium can be promoted, the growth of root systems of the crops can be promoted, and the photosynthesis of leaves can be promoted to achieve a yield increasing effect; furthermore, the potassium humate and the hollow porous carrier microspheres are matched with each other, so that the granular structure of the soil can be effectively increased, the soil structure can be improved, the fertilizer retention capacity of the soil can be improved, the release rate of the potassium phosphate can be controlled to achieve a slow release effect, and healthy and strong growth of crops is facilitated; according to the method, the ea
