摘　　要：稳定性复合肥是在生产尿基复合肥的过程中加入脲酶抑制剂,介绍了其生产工艺流程和控制要点。稳定性复合肥施入土壤后,不仅可以减少尿素中铵态氮的硝化和挥发,而且可对土壤中的磷元素起到活化作用,从而提高氮、磷利用率,延长肥效期。Stable compound fertilizer is to add urease inhibitor in the production of urea-based compound fertilizer, the production process and control points of stable compound fertilizer are introduced. The application of stable compound fertilizer into soil can not only reduce the nitrification and volatilization of ammonium nitrogen in urea, but also activate the phosphorus element in the soil, thus increasing the utilization ratio of nitrogen and phosphorus, prolonging the fertilizer effective period.

关 键 词：脲酶抑制剂 稳定性复合肥 肥效期
