水肥和钝化剂阻控水稻吸收镉机制的研究进展OACSTPCD
Research Progress on the Mechanism of Water and Fertilizer and Passivator Inhibition and Control of Cadmium Uptake in Rice
镉(Cd)污染严重威胁生态环境,Cd污染水稻会对人体健康造成极大影响,防控水稻Cd污染迫在眉睫,也是当前研究的热点之一.水肥管理和施用钝化剂是目前治理水稻Cd污染有效且主流的措施.本文综述了水稻Cd污染的现状,及水肥管理和钝化剂施用治理Cd污染的作用机制,即水肥管理主要通过吸附沉淀作用和离子竞争作用阻控,钝化剂主要通过共沉淀、络合作用、吸附和离子交换作用以及氧化还原作用进行阻控.分析了治理后的土壤环境(土壤理化性质、土壤微生物和土壤酶)变化,展望了今后的研究方向.
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.
