| titleOfInvention | Polyphosphate-containing nitrogen-phosphorus compound fertilizer and preparation method thereof |
| abstract | The invention discloses a polyphosphate-containing nitrogen-phosphorus compound fertilizer and a preparation method thereof. The preparation method of the polyphosphate-containing nitrogen-phosphorus compound fertilizer comprises the following steps: acidolysis treatment, freezing crystallization, sedimentation treatment, evaporation concentration and neutralization treatment and polymerization reaction. The method has simple process steps and easy control, can directly use the middle-low grade phosphorite as the raw material, and can prepare the nitrogen-phosphorus composite material with high phosphorus content, high polyphosphate content and water-insoluble substance less than or equal to 1.2. |
