| Abstract: | The variety and content of organic acids exuded from hydroponic Chlorophytum comosum roots,hydroponic Ipomoea aquatica roots and hydroponic Oenanthe javanica roots by liquid chromatography were studied,and the effects of organic acid of root exudates on nitrogen cycling bacteria were analysed.The results showed that organic acid of the three hydroponic plants root exudates has promotion effect on ammonifying bacteria and denitrifying bacteria,but has inhibition effect on nitrobacteria and nitrosobacteria. |

| Keywords: | hydroponic plants root exudates organic acid nitrogen cycling bacteria |
