摘　　要：缩二脲会对作物产生毒害作用,因此肥料中缩二脲含量要严格控制。研究熔体造粒尿基复合肥产品中缩二脲含量与熔融温度、停留时间和低共融体的关系。结果表明,熔融温度、停留时间、是否添加钾盐对缩二脲含量都有影响。通过设备、工艺等方面的调整,有效地降低了熔体尿基复合肥产品中缩二脲的含量。The biuret content is strictly controlled because of its poisoning effect on crop. The relationship between the biuret content of urea-based compound fertilizer and melting temperature, residence time, and low melt body is investigated. The results show that the biuret content is effected by melting temperature, residence time and potassium addition. Trough adjusting equipment, technology and so on, the biuret content of urea-based compound fertilizer is reduced.
