The invention discloses an organic ammonium phosphate fertilizer and a preparation method thereof, and belongs to the technical field of organic fertilizers. When the organic matter ammonium phosphate fertilizer is prepared, firstly, corn steep liquor and wet-process phosphoric acid are mixed and stirred to react for 4-5 h at the temperature of 100-150 DEG C, then ammonia gas is introduced or ammonia water is added, shearing emulsification or spray drying treatment is conducted, and the organic matter ammonium phosphate fertilizer is obtained. The corn steep liquor is used as a production raw material to prepare the organic matter ammonium phosphate fertilizer, the aim of recycling the corn steep liquor can be achieved, environmental pollution is avoided, the corn steep liquor is rich in nutrient components such as protein, amino acid, reducing sugar, vitamins and acid substances, a large amount of organic matter can be introduced into the organic matter ammonium phosphate fertilizer, and the organic matter a
