摘要:

我国稻田镉污染严重,稻米安全问题突出,发展能够有效调控水稻镉污染的产品与措施尤为迫切。稻田生态系统高度复杂,并易受多种因素影响,水稻镉污染调控难度大。大量研究表明,合理的水分管理不仅能够保障水稻正常的生长发育、产量和稻米品质,同时还能有效减少水稻镉积累。本文综述了水分对土壤理化性质、微生物动态变化以及植物生长发育的影响,阐述了水分管理降低水稻镉积累的主要机理,总结和展望了目前水分管理模式相关研究进展以及未来研究方向,旨在为实际生产上通过优化水分管理技术降低镉污染提供理论依据,更有效实现水稻安全生产。

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
