Abstract：Concentration of nutrient solution directly affects the yield and quality of hydroponics
vegetables．This experiment studied the effects of different concentrations of nutrient solution on the growth
quality and yield of water celery，so as to screen out suitable nutrient solution concentration for the growth
of water celery in greenhouse．The results showed that the water celery biomass，chlorophyll content，
photosynthetic parameters，total flavonoids，VC，soluble protein content，etc. indexes firstly increased and
then decreased along with the increase of nutrient solution concentration．Thereinto，1.5 times concentration of
nutrient solution was the best，which can improve the overall quality and yield of water celery．
