摘　　要：硝化抑制剂缓释尿素具有提高氮素利用率、增产、增收、节肥等功效。为验证其在水稻上的应用效果,特进行此试验。结果表明:底肥一次性施用硝化抑制剂缓释尿素或第一代缓释尿素对水稻具有不同程度的增产效果,分别增产6.7%、3.9%,净增收76.35元/667 m2、52.19元/667 m2,节省肥料、节省功时费,在生产上有一定推广价值。The slow release urea with nitrification inhibitor can increase nitrogen utilization efficiency, yield and benefit and save fertilizer. The experiment was conducted to verify the effect of slow release urea on rice and the results revealed that as basal fertilizers, the slow release urea with nitrification inhibitor and the first generation slow release urea could increase yields by 6.7% and 3.9% and net benefits by 76.35 yuan/667 m^2 and 52.19 yuan/667 m^2, respectively.
