The invention discloses a method for producing a novel fertilizer by resourcefully utilizing kitchen wastes. The method is characterized by comprising the following steps: (1) washing the kitchen wastes by using weak-alkaline waste liquid; softening and pre-immersing; (2) crushing by hydraulic power; (3) squeezing and sieving; (4) carrying out heating treatment on solids obtained by the sieving; (5) filtering; (6) mixing a filtering solution and a filtering solution obtained by the primary washing, adding optional strains, and fermenting; and (7) after fermenting, adjusting the concentration of material liquid and spraying and granulating to prepare the novel fertilizer. According to the method disclosed by the invention, a biochemical method is used for resourcefully utilizing the kitchen wastes to produce the novel fertilizer so as to reduce the cost of treating the kitchen wastes; the economic benefits are good and the quality of a product is better than (accords with) national standards; the product has high practical and promotional values.
