Abstract: |
|||
| A long-acting ammonium nitrate in the form of eutectics is prepared through such steps as dissolving dicyandiamide in water or ammonia water, pumping it into reactor for synthesizing ammonium nitrate, fully mixing with reaction solution in reactor, concentration, cocrystallizing dicyandiamide and ammonium nitrate, dewateing and drying, and features durable fertility, high utilization rate of N (increased by 5-8%), less gas exhausted as green-house effect, and high yield of crops. | |||
