The invention discloses a method for producing a high-fertilizer-efficiency organic fertilizer by utilizing monosodium waste liquid. The method comprises the step of material mixing, wherein the monosodium waste liquid, rice husk bran and chicken muck ash are mixed and stacked into a material to be fermented according to the proportion of (7-3): (2-4): (1-2); the step of fermentation, the step of screening and crushing and the step of product packaging. According to the method, the chicken muck ash with a low water content and a large PH value is selected as an auxiliary material to be mixed with the monosodium waste liquid with a high water content and a small PH value, the water and the PH value of the monosodium waste liquid can be rapidly adjusted, energy consumed by evaporation and water drying is saved, and therefore production cost is reduced. The total nutrient content of N, P and K in the organic fertilizer prepared through the method reaches above 13%, the use effect of the organic fertilizer is equivalent to the use effect of an organic and chemical fertilizer when the organic fertilizer is used for production of organic agricultural products, and the yield-increasing effect is obvious.
