摘　　要：我国农业生产氮肥投入量大,但利用率低,氮素损失严重。其中,由反硝化过程产生的氮素损失占比最高可达50%以上,有效调控土壤反硝化过程对于减少农业生态系统氮素损失、降低氮素环境污染具有重要意义。生物反硝化抑制剂(biodenitrification inhibitors,BDIs)是一类植物分泌的次生代谢产物,其中的原花青素已被证实可促进土壤氮素储存并增加作物产量,有望成为一种高效且绿色的氮素调控物质。本文系统梳理了BDIs的发现及其反硝化抑制机制,总结了目前国内外BDIs研究领域的主要进展,并对未来研究方向进行了展望,以期为BDIs施用技术及产品的开发、农产品质量的提升及现代农业绿色健康发展提供借鉴。The nitrogen fertilizer consumption in China is large,but the utilization rate is low due to serious nitrogen losses.Denitrification is the main path of nitrogen loss,accounting for more than 50%of the total N loss each year.Effective regulation of soil denitrification process is of great significance for reducing nitrogen loss in agricultural production and the induced ecosystem risks.Biodenitrification inhibitors(BDIs)are the secondary metabolites secreted by plants,which have been proved of promotion in soil N storage and crop yield,and are promising to be an efficient and green nitrogen fertilizer efficiency agent.In this paper,the discovery of BDIs was reviewed,and the main research progress on the mechanism of denitrification inhibition of BDIs was systematically summarized.The future researches are prospected,hopefully to serve as a reference for the development of BDIs technologies and products,and find an alternative way for green and healthy development of modern agriculture.
