Abstract: The paper illustrated the effect of spraying Zn and I in plot experiment. The results showed that accumulations of Zn and I are increased by spraying Zn and I in specific range and the maximum accumulation of Zn and I were 62.2 and 3.32 mg/kg respectively and the yield of Chinese cabbage increased, too. But if the concentration of Zn and I was up to a threshold, the toxicity will be produced by both of the elements.In the mean time,the effect of spraying Zn and Ion the quality of Chinese cabbage, such as nitrate and Vc content, was also studied too.
