Research Progress on the Mechanism of Water and Fertilizer and Passivator Inhibition and Control of Cadmium Uptake in Rice
Cadmium pollution poses a serious threat to the ecological environment,and cadmium pollution of rice can have a significant impact on human health.Preventing and controlling cadmium pollution in rice is urgent and one of the current research hotspots.Water and fertilizer management and the application of passivating agents are currently effective and mainstream measures for controlling cadmium pollution in rice.This article summarized the current situation of cadmium pollution in rice,as well as the mechanisms of water and fertilizer management and the application of passivating agents to control cadmium pollution.Water and fertilizer management is mainly controlled by adsorption precipitation and ion competition,passivation agent is mainly controlled by co-precipitation,complexation,adsorption and ion exchange and redox.In addition,it analyzed the changes in soil environment(soil physical and chemical properties,soil microorganisms and soil enzymes)after governing.Finally,the article prospected the future research on cadmium pollution in rice.
