Abstract | The invention discloses a sulfur, zinc, manganese and boron-containing phosphate ammoniate fertilizer and a production method thereof. The sulfur, zinc, manganese and boron-containing phosphate ammoniate fertilizer comprises the following components in part by weight: 12.9 to 13.4 parts of N, 43.9 to 44.7 parts of P, 5 to 12 parts of S, 0.98 to 1.04 parts of Zn, 0.5 to 0.53 part of Mn, 0.5 to 0.56 part of B and 1.5 to 2.4 parts of water. The production method comprises the following production steps: (1) adding diluted phosphoric acid and gas ammonia in a pre-reaction tank to perform a neutralization reaction, and concentrating the reaction solution to obtain a first material; (2) adding the first material into a quick ammonia reactor, adding liquid sulfur or mixture of liquid sulfur and 98 percent concentrated sulfuric acid, tailings pulp containing zinc, manganese and boron and an acidic dispersant into the quick ammonia reactor, and adding gas ammonia for secondary neutralization to obtain a second materia |
