Abstract:: In order to study the effects of iodinated copper-based foliar fertilizer (CBFF-I) on iodine content，yield，and quality of radish (Raphanus sativus L.) and to provide the basis for its scientifically application in practice，a pot experiment was investigated in our research，with the application of water and traditional bordeaux mixture (BDM) as comparison.The results indicated that copper content in the soil of CBFF-I treatment decreased significantly by 39.10%-50.62% compared with that of BDM treatment.However，copper contents in the plant were not significant among all treatments.In comparison to the control，treatment of 1 g?L-1 copper-based foliar fertilizer containing potassium iodate (CBFF-KIO1) increased iodine content in roots by 93.41% and the soluble protein content of roots by 39.26%.Treatment using 2 g?L-1 copper-based foliar fertilizer containing potassium iodide (CBFF-KI2) increased the soluble protein content in roots by 37.87%.Treatment of 1 g?L-1 (CBFF-KI1) decreased iodine content in roots by 44.38% and vitamin C content of root by 23.75%.CBFF-KI1 and CBFF-KI2 treatments significantly increased nitrite content by 53.95% and 92.68%，respectively.In conclusion，applying copper-based foliar fertilizer containing potassium iodate with a spraying concentration of 1 g?L-1 was recommended for radish cultivation.
