The invention discloses a production method of an amino acid daubing fertilizer. The production method comprises the following steps: uniformly mixing soybean proteins, amino acid, fulvic acid, treacle and a yeast liquid at a ratio of 2:1:1:3:3 to obtain a mixed solution, and regulating the pH value of the mixed solution to 6.5-7.5; inoculating with microbial fermentation agent, delivering into a bioreactor, and fermenting to obtain a bacterium-containing fermentation liquid; adding thiophanate methyl, sodium naphthalene-1-acetate, flusilazole and tetramycin into the bacterium-containing fermentation liquid, and uniformly stirring; then delivering to a reaction kettle, and adding chelator, major elements N, P and K, medium elements Mg and Ca and minor elements Fe, Mn, Zn, B, Mo and Cu while stirring; stirring at a constant temperature for 30 minutes to complete chelation; and putting into a cooling vessel, cooling, filtering, and automatically canning. The nutritionally balanced insecticide-fertilizer chelated by the method has the advantages of low cost, large yield, short production cycle, favorable production stability, good permeability, strong adhesion and high concentration and solid content, and greatly satisfies nutrition required for plant growth.
