The invention discloses a preparation method of a photosynthesis synergist, and the preparation method of the photosynthesis synergist comprises the following steps: step 1, adding potassium chloride KC, then adding phosphoric acid H3P04, and reacting for 1.5 hours at the temperature of 160-190 DEG C; step 2, adding the solution obtained in the step 1 into a previous batch of mother liquor, concentrating, adding solid potassium hydroxide KOH while the solution is hot, and stirring to react uniformly; step 3, detecting the pH value, dropwise adding a 40% KOH solution, and measuring the pH value while stirring while dropwise adding; 4, after cooling, crystals are naturally separated out and filtered, the crystals are washed with 150 ml of tap water for three times, washing liquid and filtrate are combined to serve as mother liquor, and the monopotassium phosphate solution is obtained.The photosynthesis synergist has the synergistic effect of a synergist, an active agent and choline chloride, the increasing effe
