摘要
既要保证氮肥在优质高效农业生产中的促进作用,又要保证农业和环境的可持续发展,如何提高氮肥利用率、减轻氮肥污染成了解决问题的关键.从氮素在土壤中的生物化学转化过程入手,通过抑制剂的施用来调控氮素的转化,减缓硝化过程的进行,是解决该问题的一种有效措施.本文从硝化抑制剂的定义、筛选硝化抑制剂的条件、国内外较受关注的硝化抑制剂品种以及硝化抑制机理等几个方面对目前的研究进展进行综述,并提出目前研究中存在的问题及今后的研究方向.
To improve the use efficiency of fertilizer N while alleviate its pollution is one of the keys in ensuring the high yield and good quality of agrieuhural products and the sustainable development of agriculture and environment, for which, applying nitrification inhibitors to retard the course of soil nitrification is an efficient measure. In this review, the definition, screening cntena, major varieties being widely used, and action mechanisms of nitrification inhibitors were introduced, and the existing problems and prospects in related researches were discussed.
