【摘要】 通过中国知网(CNKI)数据库，以“肥料增效剂”“硝化抑制剂”“脲酶抑制剂”“腐殖质”“腐殖酸”“微生物肥料”“氨基酸肥料”等为关键词搜索发表于2000—2023年的文献，并将获得的8 805篇文献记录导入VOSviewer软件中进行关键词聚类分析。结果表明：肥料增效剂主要分为生物类和化学类两大类，其中化学类肥料增效剂主要为脲酶抑制剂类和硝化抑制剂类，生物类肥料增效剂主要为腐殖质类、氨基酸类、微生物类等。概述了生物类和化学类肥料增效剂的作用原理，提出了肥料增效剂在实际应用中存在的问题，并对今后肥料增效剂的创新方向提出了展望。更多还原

【Abstract】 Through the China National Knowledge Infrastructure(CNKI) database, literature published from 2000 to 2023 is searched using keywords such as "fertilizer synergist", "nitrification inhibitor", "urease inhibitor", "humus", "humic acid", "microbial fertilizer", "amino acid fertilizer", etc. The obtained 8 805 literature records are imported into VOSviewer software for keyword cluster analysis. The results show that fertilizer synergists are mainly divided into two categories: biological and chemical. Between these two categories, chemical fertilizer synergists are mainly urease inhibitors and nitrification inhibitors, while biological fertilizer synergists are mainly humic substances, amino acids, microorganisms, etc. An overview of the working principles of biological and chemical fertilizer synergists is provided, the problems that exist in the practical application of fertilizer synergists are point out, and the innovative direction of fertilizer synergists in the future is proposed.更多还原
