| titleOfInvention | A kind of production method of water-soluble fertilizer monoammonium phosphate |
| abstract | The invention provides a method for producing a water-soluble fertilizer monoammonium phosphate, comprising the following steps: A) mixing wet-process phosphoric acid with a chelating agent, and reacting to obtain an acid solution; B) passing the acid solution in the step A) through Ammonia is introduced for partial neutralization, and then a cosolvent is added to obtain a partially neutralized slurry; C) the partially neutralized slurry is continuously fed into ammonia for neutralization, and dried after the neutralization to obtain a monoammonium phosphate product. The water-soluble fertilizer monoammonium phosphate product produced by the method of the invention has the characteristics of low water-insoluble matter content and high total nutrient content, and during the application process, since the water-soluble fertilizer monoammonium phosphate contains chelating agents and cosolvents, it is not easily affected by soil Iron, calcium, magnesium and other metal ions are fixed, but can form soluble complexes with ineffective trace elements in the soil and be absorbed by plants, which improves the utilization rate of phosphorus, nitrogen and other elements. |
