Where is the best selenium-enriched rice producing area?

Mainly rice grown naturally in several selenium-enriched producing areas. At present, this product is the best in Enshi, Hubei, Poyang, Jiangxi [1], Ziyang, Shaanxi and Wanyuan, Sichuan. Selenium in soil has high purity and no heavy metal pollution. The soil planted with selenium-enriched rice in Xinhe, Poyang, Jiangxi Province naturally contains selenium and only produces one season a year. It is non-transgenic and non-hybrid, and people can keep their own seeds. Biological pest control technology is rich in organic selenium of more than 300 micrograms per kilogram, which is a real natural healthy selenium-enriched rice. The yield of non-hybrid non-transgenic rice is extremely low, so the price is relatively high.
