摘　　要：在稀土碳铵复混肥生产过程中掺入新选用的调理剂,既提高了肥料中氮的稳定性,也确保了其水溶性磷达标;采用挤压造粒方式一次成型,工艺简炼,投资省、占地小。In the production process of rare- earth added ammonium carbonate compound fertilizer, a newly selected amendment is to be blended in. The new process not only stabilizes the nitrogen content of the compound fertilizer , but also ensures the soluble phosphorus standard. The title product is finally granulated with extruder. The technology is simple; its investment is economical; and its production site is small.
