Description

Production method of selenium-rich rice
Technical Field
The invention relates to the technical field of planting, in particular to a production method of selenium-rich rice.
Background
Selenium element has anticancer and cancer preventing effects, and can cause cardiovascular and cerebrovascular diseases due to selenium deficiency. Selenium is mainly from food, and the selenium deficiency in food is the main reason for the selenium deficiency of human body. Two thirds of areas from east to west of China are in selenium-deficient areas, selenium deficiency of plants is caused by insufficient content of selenium in soil, and finally selenium deficiency of human bodies is caused by low content of selenium in agricultural products. Although the selenium content in some soil can reach the selenium-rich or selenium-rich level, the selenium content in agricultural products is insufficient due to the limited absorption capacity of plant roots. With the improvement of living standard and the enhancement of health consciousness of people, the demand of high-quality and functional selenium-rich foods (selenium-rich rice, selenium-rich flour and the like) is increased. Generally, the purpose of selenium enrichment of rice can be achieved by applying selenium fertilizer to soil and spraying selenium fertilizer to leaf surfaces, but the selenium fertilizer applied to soil has the defects of large selenium fertilizer consumption, high cost, weak root system absorption capacity, secondary soil pollution caused by heavy metal brought by mineral selenium and the like.
