Table 1 DBP concentrations in the nutrient solution for six vegetables (Kangresijiqing (KRSJQ), Xiadiqing (XDQ), Ziyoucai (ZYC), Aijiaohuang (AJH), Shanghaiqing (SHQ) and Gaogengbai (GGB)). Each treatment consisted of five replicates. The values with the different letter(s) were significantly different (p < 0.05)
