The invention relates to a synergistic fertilizer, in particular to a solanaceous polyamino acid synergistic fertilizer and a preparation method thereof. The synergist is prepared from a urease inhibitor, an ammonia stabilizer, polyurethane, a biological agent, an insecticide and a plant growth promoter. The inhibitor is used for controlling the activity of soil enzyme, so that the conversion and form of the fertilizer are controlled, the loss is reduced, the effective period is prolonged, and the utilization rate is increased; organic and inorganic matter coating technologies are utilized to control the contact between the fertilizer and water and slow down the dissolution rate, so that the loss is reduced, and the utilization rate is increased; organic polymer substances are complexed with nutrient ions to form organic copolymer active substances, so that the rhizosphere nutrient concentration is increased, the loss is reduced, and the fertilizer utilization rate is increased. 本发明涉及一种增效肥料，特别涉及一种茄果类聚氨酸增效肥料及其
