The invention relates to the technical field of fertilizers and particularly relates to a production process of a high-nitrogen sulfur-based compound fertilizer. The production process of the high-nitrogen sulfur-based compound fertilizer comprises the following steps: mixing nitrogen-phosphorus-potassium compound fertilizer material pulp with sulfur sol to obtain a compound base material, then mixing the base material with ammonium hydrogen carbonate powder, granulating, drying at low temperature, polishing and screening to produce the high-nitrogen sulfur-based compound fertilizer. The fertilizer is capable of supplying abundant nitrogen, phosphorus and potassium elements to crops, is applicable to acid soil or alkaline soil, and is capable of increasing the concentration of carbon dioxide around the crops, effectively accelerating photosynthesis of the crops and improving the yield and the quality of the crops. 本发明涉及肥料技术领域，尤其涉及种高氮硫基复合肥的生产工艺，通过将氮磷钾复合肥料浆与硫溶胶混合得到复合基料，然后将基料与碳酸氢铵粉末混合、造粒、低温干燥、抛光和筛分后，生产出高氮硫基氮磷钾复合
