At present, there are three sections: selenium-enriched fishing area, selenium-enriched breeding area and selenium-enriched picking area.
Selenium-enriched agricultural products look almost the same as ordinary agricultural products, but their value is much higher, mainly because selenium-enriched fruits and vegetables, wheat, meat and poultry can not only supplement human selenium, but also have important functions such as anti-cancer, anti-aging and exemption from heavy metal poisoning.
Top Ten Selenium-enriched Areas in China
Enshi, Hubei 1
Enshi is located in the southwest of Hubei Province, at the junction of Hubei, Hunan and Chongqing provinces (cities), with a magical latitude of 30, and is the location of "the only proven independent selenium deposit in the world".
The domestic selenium mineral reserves rank first in the world, and it has the richest natural biological selenium resources in the world. It is known as the "world's first natural selenium-enriched biosphere" and is one of the most suitable areas for human habitation.
2. Shaanxi Ankang
Ankang, located in the southeast of Shaanxi Province, is one of the largest selenium-enriched areas in China. The whole city 10 counties are in selenium-enriched ecological environment to varying degrees. The selenium-rich stratum in Ankang is 40-50 meters thick and is rich in selenium resources.
In recent years, Ankang has transformed the advantages of selenium resources into industrial advantages and economic growth advantages, taking the research and development of selenium-enriched products, especially selenium-enriched foods, as the leading industry, building a natural selenium-enriched brand, and striving to build it into a selenium-enriched industrial cluster in China Selenium Valley.
3. Yichun in Jiangxi Province
Yichun, located in the northwest of Jiangxi, is a famous natural selenium-enriched area in China, which is famous for its selenium-enriched hot springs.
Especially in Wentang Town, which is located in the southwest of the main city 15km, there is an ancient well with a history of more than 800 years. It is a unique selenium-enriched hot spring in China, comparable to the world-famous French Akers mineral spring.
In addition, Mingyue Mountain in Wentang Town has beautiful scenery and combines heroism, strangeness, seclusion, danger and beauty. It is known as the "hometown of Chang 'e" in the name of the moon.
4. Sichuan Wanyuan
Wanyuan City, located in the northeast of Sichuan, is named because it is located in Wanqingchi and the source of all kinds of water.
Located in the northeast of Sichuan Province, in the hinterland of Daba Mountain, at the junction of Sichuan, Shaanxi and Chongqing, and at the intersection of seven counties and cities, it is the dividing line between the northern and southern climate of China, and also the watershed between Jialing River and Hanjiang River. In the center of Daba Mountain, it enjoys the reputation of "the source of wanbao".
In 2007, experts and scholars from Chengdu University of Technology made a systematic and scientific sampling of soil and some agricultural products in Wanyuan City. Through analysis and testing, it is scientifically proved that Wanyuan City belongs to the only natural selenium-enriched area in Sichuan.
For Wanyuan, selenium enrichment is one of the biggest characteristics of agricultural products.
5. Taoyuan in Hunan Province
Taoyuan County belongs to Changde City and is located in the northwest of Hunan Province. Taoyuan County was awarded the title of "Top Ten Selenium-enriched Hometown in China" by China Selenium-enriched Alliance, and only Taoyuan in Hunan Province won this honor.
According to the research report of Chinese Academy of Sciences, the soil selenium content in Taoyuan County is higher than the world median selenium content (0.40mg/kg) and the average selenium content in China (0.29mg/kg), and the soil with selenium content > 1 mg/kg in Taoyuan County accounts for about 3% of the county area.
6. Kaiyang in Guizhou
Kaiyang county is located in the hinterland of central Guizhou, in the sub-central area connecting Guiyang and Zunyi.
Kaiyang County has the reputation of "Hometown of Prose Poetry in China", "Hometown of Selenium-enriched Agricultural Products in China", "Green Phosphorus Capital in China" and "Karst Ecological World Park". It is the first demonstration base county of phosphorus and coal chemical industry in circular economy in China and a strong county in Guizhou Province.
7. Fenghua Zhejiang
Fenghua, which belongs to Ningbo City, is located in the eastern coast of Zhejiang Province and is a well-known selenium-rich area. Nan 'ao Village in Chun Hu Town is one of the famous longevity villages in Zhejiang Province. The village's longevity culture and health preservation culture have a long history and rich connotations.
Through scientific research, it is found that the selenium content in the soil of Nan 'ao Village is more than five times the national average. The mystery of villagers' longevity in Nan 'ao Village is closely related to the rich selenium in the soil besides the unique natural environment in the village.
8. Yongfu in Guangxi
Yongfu County belongs to Guilin City and is located in the northeast of Guangxi. Yongfu county has many hills and mountains, which belong to typical karst landform.
The selenium content of soil in Yongfu County is 3.8 times of the national average. Through excavation and introduction, the county has decided to develop three leading products: Siraitia grosvenorii, selenium-enriched rice and selenium-enriched sugar orange, and strive to turn the selenium-enriched advantage into the advantage of enriching the people.
9. Peace in Qinghai
Ping 'an District is located in the east of Qinghai Province and belongs to Haidong City.
The selenium-enriched soil in Ping 'an District covers an area of more than 600 square kilometers, and the average selenium content is 0.44mg/kg, which is higher than the national soil background value. Thick soil layer and moderate selenium content are suitable for development and utilization, reaching sufficient or moderate selenium level.
10, Bama, Guangxi
Bama Yao Autonomous County, located in the northwest of Guangxi, is known as the "Holy Land of China". According to the investigation of Chinese Academy of Sciences, Bama is rich in soil selenium resources, and the selenium content in soil and grain is more than 10 times higher than the national average.
