Abstract：

In order to explore the mechanism of different foliar fertilizers in preventing and controlling cadmium enrichment in rice, and to provide scientific basis for solving the problems of heavy metal cadmium pollution and food safety in farmland. This study summarizes the growth hazards of cadmium on rice, including the characteristics of nutrient absorption by rice leaves and foliar fertilizers, the types and characteristics of foliar fertilizers, and the mechanism by which foliar fertilizers inhibit and control cadmium enrichment in rice. Identify the factors that affect the effectiveness of foliar fertilizers in preventing cadmium enrichment in rice, such as weather, temperature, utilization rate, spraying frequency, and concentration. Propose a series of prospects, including combining with other prevention and control measures, conducting research on other types of foliar fertilizers, continuing theoretical research on foliar fertilizers, and strengthening unified management and standardized operation techniques.
