摘　　要：在制造高塔尿基复合肥的基础上,通过合理搭配原料及添加中微量元素,研发了一种含硝态氮、铵态氮、酰胺态氮等多形态氮素蔬菜专用肥。介绍了蔬菜专用肥的工艺流程、技术指标和配方,并有效解决产品吸潮问题。大白菜种植试验表明,该肥氮肥利用率提高9.3百分点,白菜的营养品质明显改善。Based on urea-based compound fertilizer by tower granulation, the special fertilizer for vegetables is produced by adjusting material combinational proportions and adding medium element and trace element, which contains nitrate nitrogen, ammonium nitrogen and amide nitrogen. The production process, technical index and formulas of special fertilizer for vegetables are introduced. The product moisture absorption problem is effectively resolved. Cabbage planting test shows that the utilization rate of nitrogen is increased by 9.3 percentage points, the nutrition of cabbage is improved significantly.
