摘　　要：复合肥长效添加剂是将脲酶抑制剂、硝化抑制剂、磷活化剂有机结合,利用其协同作用比单一抑制剂使肥料具有更长供肥期和更高利用率,达到一次性投肥免追肥的目的。这是提高作物产量和提高化肥利用率的有效手段之一,应大力推广在复混肥中添加这种长效添加剂(NAM)。The mechanisms of long-effect fertilizer lies in synergic function of urease inhibitor, nitrification inhibitor as well as phosphate activator, Which result in producing longer and better effects than any single inhibitor, thus achieving higher fertilizer efficiency and avoiding top dressing. As one of the effective approaches in improving fertilizer efficiency and increasing yield, the addition of the long-effect additive （NAM） in compound fertilizer is recommended.
