| titleOfInvention | Preparation method of liquid fertilizer containing rich phosphorus and potassium |
| abstract | The invention discloses a preparation method of liquid fertilizer containing rich phosphorus and potassium, which comprises the following steps: adding monopotassium phosphate into water, then adding potassium sulfate or potassium chloride, heating for dissolving, adding urea after stopping heating, dissolving to prepare solution A; adding hydroxyl-ethyl diphosphonic acid into the solution A, or dissolving hydroxyl-ethyl diphosphonic acid by water to prepare solution B, and then adding the solution B into the solution A; stirring to completely dissolving the matter in mixed solution, adding potassium hydroxide and dissolving, adding ammonium polyphosphate solution, evenly mixing to prepare solution C; dissolving fulvic acid and / or pyrotomalenic acid by water to prepare solution D; slowly adding the solution C into the solution D while stirring, and then stirring to react for 15-60 min; and finally diluting with water to a fixed quantity. The liquid fertilizer prepared by the invention has high content of phosphorus and potassium, and the appearance thereof is clear and dark brown liquid. Through 0 DEG C crystallization observation, no precipitation appears, thus the liquid fertilizer can be placed for a long time. |
