The invention discloses a fertilizer slow-release synergistic agent and a preparation method thereof. The fertilizer slow-release synergistic agent comprises the following raw materials in percentage by mass: 0.1-20 % of polyaspartic acid and slat thereof, 0.1-10 % of urease inhibitor, 0.1-30 % of nitrification inhibitor, 0.03-5 % of plant growth regulating agent, 10-35 % of soil regulating agent and 10-80 % of carrier. The fertilizer slow-release synergistic agent disclosed by the invention is mainly used for the slow-release synergism of a compound mixing fertilizer, is increased in the utilization rate of the fertilizer, and is capable of effectively improving the soil, and the soil moisture can be preserved; and when the fertilizer slow-release synergistic agent is used, the fertilizer slow-release synergistic agent can be added into a material feeding system or an enveloping drum together with the fertilizer raw materials and mixed with the fertilizer raw materials, the effect of slow-release synergism can be realized, and the dosage of the fertilizer slow-release synergistic agent is 4-8 kg per ton fertilizer.
