Abstract

The invention discloses a tower type melt granulation stable nitrogen fertilizer and a preparation method. The nitrogen fertilizer contains synergistic components of potassium fulvate, N-(n-butyl)thiophosphoric triamide, 3,4-dimethyl-1h-pyrazolium dihydrogen phosphate and the like besides common nitrogen containing fertilizers of urea, ammonium sulfate, ammonium chloride, ammonium nitrate-phosphorus. The stable nitrogen fertilizer is manufactured by adopting a tower type melt granulation technology, the mechanical strength of granules is high and the granules are difficult to powder. Tests on corns, wheat, cucumbers and rice show that the stable nitrogen fertilizer can reduce the application amount of nitrogen fertilizer, yield increase is effective, the nitrate content in soil can also be reduced, and the stable nitrogen fertilizer is a green and environment-friendly excellent fertilizer.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a tower type melt granulation stable nitrogen fertilizer and a preparation method thereof. Background technique [0002] Nitrogen fertilizer is a major artificial nutrient fertilizer, which plays an important role in ensuring and improving crop yield. Although my country is currently the largest producer and seller of nitrogen fertilizers in the world, the utilization rate of nitrogen fertilizers in my country is only about 50% of that of developed countries. The lost nitrogen fertilizers not only cause huge direct economic losses, but also cause environmental pollution. Therefore, it is imminent to improve the utilization efficiency of nitrogen fertilizer. The types of nitrogen fertilizers include amide nitrogen fertilizer, ammonium nitrogen fertilizer and nitrate nitrogen fertilizer. Among them, crops directly absorb ammonium nitrogen and nitrate nitrogen, and only directly absorb trace amounts...
