| titleOfInvention | A kind of production method preparing potassium primary phosphate by-product shepherd's purse special fertilizer |
| abstract | The present invention relates to chemical technology field, especially a kind of production method preparing potassium primary phosphate by-product shepherd's purse special fertilizer, by carrying out research and analysis to the demand of shepherd's purse nutrient composition content, and carry out regulating to the constituent content in production process and arrange in pairs or groups, make the composite fertilizer of the chemical combination state prepared can meet the demand of crop to greatest extent, and reduce in composite heat transfer because element mismatch, the high cost caused, further avoid too much element to drop among soil, that causes composite fertilizer solidifies soil and contaminate environment. |
