The invention discloses a production method of ammonium phosphate containing trace elements. The production method is characterized by adopting a manner of dissolving by phosphoric acid and carrying out full ammonolysis reaction on oxides or salts containing trace elements in the ammonium phosphate production process, and specifically comprises the following steps: adding oxides or salts containing trace elements into an acidolysis tank; recovering a scrubbing solution, phosphoric acid and water from an ammonium phosphate scrubbing system and mixing and stirring; fully decomposing the oxides or salts containing trace elements to ions or complexes to form a phosphoric acid solution containing trace elements; conveying to an acid preparation tank of a tubular reactor by a feed pump; adding phosphoric acid, the scrubbing solution and process water to mix; quickly ammonifying in a tubular reactor and grouting and pelleting in a pelletizer; and then drying, sieving, cooling and wrapping to obtain an ammonium phosphate compound fertilizer containing trace elements. The ammonium phosphate compound fertilizer containing trace elements obtained by adopting the method has good solubility.
