The invention discloses a preparation method of a pawpaw bio-fertilizer additive, which comprises the following steps: collecting pawpaw seeds, adding water, stirring, extracting, concentrating to obtain a concentrated solution containing pawpaw seed gum, and crushing the pawpaw seeds to obtain pawpaw seed powder; crushing papaya residues, mixing the crushed papaya residues with citric acid, papaya seed powder and water, filtering, mixing the filtered papaya residues with water and a complex microbial inoculant for fermentation to obtain a primary fermentation product, mixing the primary fermentation product with water, peanut residues and cottonseed residues, and continuing fermentation to obtain a secondary fermentation product; adding charcoal, chitosan and potassium persulfate into the concentrated solution, mixing and reacting, adding the secondary fermentation product, stirring and mixing to obtain a mixture, and then feeding the mixture into a granulator for granulating to obtain the pawpaw bio-fertili
