摘　　要：硝化/脲酶抑制剂对于解决氮肥,特别是尿素及含尿素肥料施用带来的问题已经显示其效果和很好的应用前景。大量的实验室和田间实验表明,与传统肥料相比,添加硝化/脲酶抑制剂的肥料对尿素氮的转化、氨的挥发、土壤中的硝化、反硝化作用以及作物产量、环境效益等方面起到了积极的作用。当今,在世界肥料市场已经有几十种抑制剂申请了专利,其中有四种抑制剂西吡(Nitrapyrin)、双氰胺(DCD)、n-丁基硫代磷酰三胺(NBPT)和氰醌(HQ)大量应用于农业生产。Nitrification-urease inhibitors have shown fine efficiency and applied intensively for solving the problems of applied urea or urea-containing fertilizers.Many experiments in laboratory and fields had shown that fertilizers added with nitrification-urease inhibitors have advantage to urea transform, volatilization of ammonia, nitrification and denitrification in soils, yield and the environments. Nowadays, There are tens of inhibitors had patented,of which four inhibitors Nitrapyrin、DCD、NBPT and HQ had applied in agriculture.
