Method for producing fertilizer by using hermetia illucens culture feces and fertilizer

The invention discloses a method for producing a fertilizer by using hermetia illucens culture feces and a fertilizer. The fertilizer is prepared from raw materials and fermentation materials. The rawmaterials comprise the following components (by weight): feces, peat soil, lignite, diatomite, zeolite powder, ammonium sulfate, calcium phosphate, potassium phosphate, fulvic acid potassium salt, sodium humate, calcium peroxide and sodium perborate. The fermentation materials comprise complex probiotics, chitosan oligosaccharides and molasses. The fertilizer can be used for water purification and improvement in the aquaculture industry, and can thoroughly remove harmful substances such as excessive ammonia nitrogen and organic pollutants in water, inhibit reproduction of harmful algae and fungi, eliminate growth of pathogenic microbial factors, maintain the micro-ecological balance of water bodies, regulate the circulation of materials and energy flow of water bodies, repair the environment of aquatic water, and
