Types and Working Principles of Fertilizer Synergists
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.
