摘要：

我國(guó)稻田鎘污染嚴(yán)重,稻米安全問(wèn)題突出,發(fā)展能夠有效調(diào)控水稻鎘污染的產(chǎn)品與措施尤為迫切。稻田生態(tài)系統(tǒng)高度復(fù)雜,并易受多種因素影響,水稻鎘污染調(diào)控難度大。大量研究表明,合理的水分管理不僅能夠保障水稻正常的生長(zhǎng)發(fā)育、產(chǎn)量和稻米品質(zhì),同時(shí)還能有效減少水稻鎘積累。本文綜述了水分對(duì)土壤理化性質(zhì)、微生物動(dòng)態(tài)變化以及植物生長(zhǎng)發(fā)育的影響,闡述了水分管理降低水稻鎘積累的主要機(jī)理,總結(jié)和展望了目前水分管理模式相關(guān)研究進(jìn)展以及未來(lái)研究方向,旨在為實(shí)際生產(chǎn)上通過(guò)優(yōu)化水分管理技術(shù)降低鎘污染提供理論依據(jù),更有效實(shí)現(xiàn)水稻安全生產(chǎn)。

Abstract:

Cadmium （Cd） contamination of paddy field is serious which threaten to the rice safety of China. It is urgently to develop products and measures which can control the Cd contamination effectively in rice. It is difficult to prevent and control Cd contamination of rice without fail because paddy ecosystem is highly complex and susceptible to various factors. Numerous studies have shown that reasonable water management technology can not only ensure the good growth and yield of rice, but also effectively reduce Cd accumulation in rice. In this paper, the effects of water on soil physical and chemical properties, microbial dynamics and plant growth were reviewed,and the relevant main principles of water management to reduce cadmium accumulation in rice were expounded. What’s more, the current research progress related to water management models was summarized and future research direction was prospected. The aim is to provide a theoretical basis for optimizing the application of water management technology to reduce cadmium contamination in actual production, which leads to the realization of rice safety production more effectively.

Key words: rice, water management, cadmium contamination, soil, mechanism
