The invention relates to a fertilizer synergist containing fish protein oligopeptide and a preparation method of the fertilizer synergist. The fertilizer synergist comprises 60-80 parts of fish protein powder, 5-10 parts of a carbon source, 3-5 parts of a nitrogen source, 0.4-0.6 part of a soil loosening agent, 1.2-1.5 parts of medium trace elements and 0.5-1.2 parts of a crop growth regulator. The preparation method comprises the following steps: weighing fish protein mixed peptide powder, the carbon source, the nitrogen source, the soil loosening agent, the medium trace elements and the cropgrowth regulator; adding water, and carrying out uniform stirring to prepare a mixed solution; subjecting the obtained solution to filter pressing with a filter press; adding 2-5 parts of boric acidinto a filtrate obtained in the previous steps; adjusting the pH value of the obtained solution to 7.5-8.5 by using a hydrochloric acid solution containing 3-5% of acetic acid; and carrying out evaporation and concentration, a
