In order to introduce and apply Korean water-soluble ion silicic fertilizer，celery took as the research object，greenhouse and field experiments were carried out to explore its influence on the growth and quality of celery.The results showed that 500，1000 and 1500 times of water soluble ionic silicate fertilizer promoted the growth and improved the quality of celery.Among them，the 1000 times treatment had the significant effect in both greenhouse and field experiments. Compared with CK，the growth indicators of celery，including root length，plant height，fresh weight，dry weight and chlorophyll increased by 32.84%，12.07%，36.68%，79.91% and 43.53% on average，respectively.The quality indicators of vitamin C，soluble sugar，protein and soluble solids contents increased by 48.18%，122.97%，68.78% and 37.63% on average，respectively，compared with CK，while the nitrate nitrogen content decreased by 36.68%.In summary，the water soluble ion silicic acid fertilizer can promote the growth and improve the quality of celery，which provides a reference for the introduction and field application of the water soluble ion silicic acid fertilizer.
