  • Online:2020-11-20 Published:2020-11-20

摘要: 镉是一种生物毒性很强的重金属元素。土壤镉超标不仅影响水稻的生长发育,还会通过食物链进入人体,对身体健康造成极大危害。本文从镉低积累水稻品种选育、土壤修复、农艺措施等方面综述了调控水稻镉积累的主要技术措施及其成效,并探讨了今后水稻镉低积累研究工作的方向和建议,为防治稻田镉污染提供参考。

Abstract: Cadmium is a heavy metal with strong biological toxicity. The excess of cadmium in soil not only affects the growth and development of rice, but also enters human body through the food chain, which could cause great harm to the health of people. In this paper, the main technical measures and their effects of regulation and control of cadmium accumulation in rice were summarized, including the selection of rice varieties resistant to cadmium accumulation, soil remediation and agronomic measures. The direction and suggestions for the future research on low cadmium accumulation in rice were discussed from the aspects of variety improvement, soil remediation and agronomic methods, so as to provide some references for the prevention and control of cadmium pollution in rice fields.

Key words: rice (Oryza sativa L.), cadmium accumulation, control technology
