摘　　要：氮素是作物生长的关键限制性营养元素之一,氮循环是全球生物地球化学循环重要组成部分,主要包括生物体内有机氮的合成、氨化作用、硝化作用、反硝化作用和固氮作用。腐植酸类物质是地球上最重要的有机碳库,参与到地球碳氮循环的各个方面。本文阐述了腐植酸与氮循环各环节的关系,对解析腐植酸在地球化学氮循环中的作用、合理施用腐植酸类肥料调控和管理氮平衡、开发腐植酸产品均具有重要意义。Nitrogen is one of the key limiting nutrient elements for crop growth.The nitrogen cycle is an important part of the global biogeochemical cycle.It mainly includes organic nitrogen synthesis in the organism,ammoniation,nitrification,denitrification and nitrogen fixation.Humic acids are the most important organic carbon pools on the planet that participate in all parts of the carbon and nitrogen cycle.This article discusses the relationship between humic acid and each steps of the nitrogen cycle.It is of great significance to comprehend the role of humic acid in the geochemical nitrogen cycle,regulating and managing the nitrogen balance by rational application of humic acid fertilizers,and developing humic acid products.
