The invention relates to the technical field of fertilizers, and discloses a fertilizer additive with a growth promoting function and a preparation method thereof.The fertilizer additive is prepared from, by mass, 0-35% of water-soluble amino acid, 0-10% of fish protein, 20-40% of selenium yeast, 15-50% of glucose oxidase, 0-30% of chelated trace element fertilizer and 0-25% of humic acid. The chelated trace element fertilizer is a powdery water-soluble chelated trace element with the fineness of 100-400 meshes, and the humic acid is an organic substance with the fineness of 100-400 meshes, which is formed by decomposition and conversion of animal and plant remains through microorganisms and a series of processes of geochemistry and is accumulated. The product is a microbial fermentation product. The fertilizer additive with the growth promoting function and the preparation method thereof have the advantages of being wide in application range, high in water solubility, easy to absorb, green, environmentally f
