Scientific research projects gave birth to "Chinese natural selenium-enriched agricultural product base"

At a news conference held by the Sichuan Provincial Government Information Office recently, Guo Yongxiang, vice governor of Sichuan Province, said that “China's natural selenium-rich agricultural product base” will be built in Wanyuan City, the province’s only natural selenium-rich area, with a huge development potential. Selenium industry.

Studies have shown that the contribution of selenium to health is mainly antioxidant, immune function, and prevention and treatment of cancer. Selenium deficiency can cause Keshan disease and Kashin-Beck disease. Some cancers and cardiovascular and cerebrovascular diseases are also related to selenium deficiency.

According to Ni Shijun, vice president of Chengdu University of Technology, from April 2006 to December 2007, the university and Dazhou City and Wanyuan City Science and Technology Department carried out a “city-school cooperation” scientific research project “Selenium Geochemistry in Wanyuan City, Sichuan Province. "Characteristics and development value research" not only found that most of the soil in Wanyuan City was of high quality and clean selenium-rich soil, but also found the relationship between the degree of selenium in the soil and the longevity of local residents. This laid the foundation for the construction of Wanyuan, a selenium-rich industrial base.

This research project found that there is a large area of ​​selenium-rich soil in Wanyuan City. Local selenium is abundant in local tea, rice, corn, potato, walnut and other crops. It is a natural selenium-enriched crop, and the selenium content of crops. It is safe and effective.

Chen Zhonghua, Party Secretary of Wanyuan City, said: “Enhancing selenium-enriched industries is an important measure to develop Wanyuan’s unique economy. Last year apart from developing domestic markets such as Chengdu, Chongqing, Wuhan, and Guangzhou, selenium-rich agricultural products also earned more than US$600,000 in foreign exchange through exports. In the next few years, we will nurture and expand the selenium-enriched green industry, enriching selenium-enriched green tea, old hospital black chickens, rare Chinese herbal medicines, high-quality selenium-enriched potatoes, plateau goats, high-quality rice, edible fungi and other selenium-enriched pillar industries. Natural selenium-enriched agricultural product base'."

Ni Shijun said: "China has a small selenium-rich zone and a relatively low level of dietary selenium deficiency. Selenium is supplemented by food to prevent the lack of selenium in the human body, which will help increase the health of the people in selenium-deficient areas. Selenium-deficient people should eat more like Garlic, seafood, sesame, wheat, corn, Chinese cabbage, squash and other foods containing more selenium."
