The results showed that controlling certain salinity 500 mg/kg, could improve the quality of carrot. Because the salinity of 500 mg/kg had no effect on the chlorophyll content of carrot, and high salinity caused total chlorophyll content decreased, low salinity was conducive to the promotion of carrot synthesis of vitamin C and soluble proteinsoluble sugar content of carrot was decreased by the increasing of salinity levels, Nitrate content in carrots increased at the high salinity ( 2500 mg/kg ) treatment.
