Abstract:

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.

Key words: Hunan, Cadmium Pollution, Ratoon Rice, Development Countermeasure, Regulation of Agronomic Measures, High-yield Cultivation Technology System
