水稻镉污染相关农艺调控技术研究与应用进展

水稻是我国主要的粮食作物之一,稻米安全生产正受到农田镉污染的严重威胁,减少水稻镉污染的农艺技术发展也备受关注。本文简要阐述了水分管理技术、合理施肥技术、叶面阻控技术、原位钝化修复技术、微生物修复技术、种植制度调整以及种植镉低积累品种等农艺调控技术控制水稻镉污染的研究与应用,并对存在的问题及今后的发展方向进行了探讨与展望,以期为更有效调控水稻镉污染提供理论依据和技术支撑。

Advances in Research and Application of Agronomic Control Technologies Related to Cadmium Contamination in Rice

As one of the main food crops in china, the production safety of rice is seriously threatened by the cadmium contamination in paddy fields. The development of agronomic practice which is economic and efficient for the regulation of cadmium contamination in rice has drawn wide attention. This paper briefly expounded a serious of researches and applications in agronomic practices for the regulation of cadmium contamination in rice, such as water management, rational fertilization technique, foliar fertilizer application, in-situ passivation technique, microbiological remediation, adjustment of cropping system, planting of cultivars with low accumulation of cadmium and so on, also discussed the disadvantages of these agronomic practices and proposed the direction of future development. It is expected to provide academic reference and technical support for more effective regulation of cadmium contamination in rice.
