摘要
为了促进湖南省再生稻健康发展,本研究综合前人对湖南省水稻镉污染防治与调控以及再生稻研究成果,在湖南省大力发展再生稻的背景下,结合湖南省土壤与稻米镉污染的现状以及再生稻的优势,归纳了当前再生稻镉污染研究的薄弱环节以及空白。提出了今后再生稻镉污染需解决的重点问题:一是对不同程度镉污染区再生稻作安全生产评价,二是明确农艺措施对再生稻镉吸收与分配的调控效应,三是集成镉污染区再生稻安全高产栽培技术体系。
The paper aims to promote the healthy development of ratoon rice in Hunan. Under the background of developing ratoon rice vigorously in Hunan, according to the research results on the prevention and control of cadmium pollution and the ratoon rice in Hunan, and combined with the present situation of soil and rice cadmium pollution and the advantages of ratoon rice, we summarized the loopholes in the current study of ratoon rice contaminated by cadmium, and pointed out key problems to be solved in cadmium contamination of ratoon rice in the future:(1) evaluating the safe production of ratoon rice in cadmium-contaminated areas to varied degrees;(2) clarifying the regulating effect of agronomic measures on cadmium absorption and distribution in ratoon rice;(3) integrating the safe and high-yield cultivation technology system for ratoon rice in cadmium-contaminated area.
