Description

technical field

[0001] The invention relates to a method for reducing the cadmium content of brown rice in potted rice by adjusting soil indexes, in particular to the method for reducing the cadmium content of the main rice variety in Tianjin area, and belongs to the field of heavy metal pollution prevention and control of agricultural products. Background technique

[0002] Rice is the grain crop with the largest planting area and the highest yield per unit area in my country. Nearly two-thirds of the country's population uses rice as a staple food. The quality of rice not only directly affects human health, is related to the improvement and improvement of the quality of life of the people, but also plays a key role in social stability.
