摘要:

为了解水稻Cd污染及调控治理进展情况,从水稻Cd的吸收和转运规律、不同水稻品种类型和器官的Cd累积规律、Cd对水稻产量和品质的影响、Cd对水稻种子萌发的影响、Cd对水稻生长发育及生理生化的影响以及减少Cd积累的调控措施出发等方面进行了全面综述。针对中国水稻Cd污染情况提出今后研究方向:(1)开展新型原位钝化材料的研发,如纳米吸附材料等,此材料应具有绿色环保、廉价高效和使用便捷等特点;(2)研发出更多科学合理的土壤修复技术,在不破坏土壤自身结构和生态环境的前提下,高效去除土壤中的各类重金属;(3)运用分子新型育种手段,培育一批耐Cd和Cd超低积累稳定型品种,同时围绕品种研发相配套的栽培技术。研究以期为Cd污染治理提供一些参考。

Abstract:

To understand the current status of Cd contamination and regulation in rice, this review comprehensively summarizes the following aspects: the absorption and translocation patterns of Cd in rice, Cd accumulation characteristics in different rice varieties and plant organs, the impacts of Cd on rice yield and quality, the effects on seed germination, as well as the influences on rice growth and physio-biochemical processes. Additionally, mitigation strategies for reducing Cd accumulation are systematically discussed. Based on China's current situation of rice Cd contamination, future research directions are proposed: (1) developing novel in-situ passivation materials, such as nano-adsorbent materials, which should have the characteristics of eco-friendly, cost-effective, high-efficiency, and user-friendly features; (2) creating more scientifically sound soil remediation technologies that can efficiently remove various heavy metals without damaging soil structure and ecological balance; (3) employing novel molecular breeding techniques to cultivate Cd-tolerant and stable ultra-low Cd-accumulating rice varieties, along with developing corresponding cultivation practices. This study aims to provide valuable references for Cd contamination control.
