摘要：Background and Objective: Cadmium is one of the heavy metal elements in the farmland and rice pollution in China. Rice is one of the main food crops in China, how to reduce the accumulation of Cd in rice to ensure the safety of rice Cd has become a hot topic recently. Methodology: This experiment mainly study the effects of exogenous FeSO4·7H2O on the accumulation of Cd in edible rice, Yongyou 9th as study materials was selected through soil application of FeSO4·7H2O. The field experiments were conducted in a highly Cd polluted area (Taizhou, Zhejiang). Study on the effects of exogenous FeSO4·7H2O on the agronomic characters of rice the Cd content in different parts of rice and the soil properties . Results: The results showed that soil application of FeSO4·7H2O did not significantly affect the agronomic traits and yield of rice but it can reduce the accumulation of Cd in edible rice, among them the Cd content decreased by 21.80% in rice, exogenous FeSO4·7H2O treatment increased soil organic matter and soil pH value significantly but also reduce the content of soil available Cd. The results showed that exogenous FeSO4·7H2O through influencing the physical and chemical properties of soil and the content of available Cd in soil, so as to reduce the absorption and accumulation of Cd in different parts of rice. Conclusion: Therefore, the exogenous FeSO4·7H2O can be used as a potential and effective control technology for Cd pollution in edible rice. To a certain extent, it can ensure the safety of edible rice.
