China News Service, Qinghai Pingan, December 17th (Li Jun) On the 17th, the reporter learned from the Government Office of Pingan District, Haidong City, Qinghai Province that the Geological Society of China announced the results of the first batch of natural selenium-rich land in the country, located in Pingan District, Haidong City. 104,200 mu was recognized, and a nationally unified numbered natural selenium-enriched land identification authorization certificate was issued. This is also the only county in Qinghai and Tibet that is "on the list".
It is reported that the 104,200 mu of natural selenium-rich land approved this time belongs to Sanhe Town and Hongshuiquan Township, Pingan District. The two plots are classified as green selenium-rich land, with a soil selenium content greater than 0.3 mg/kg, and heavy metals in the soil. The content is far below the risk control value, and the soil fertility is at the level of 1 to 2.
Compared with other selenium-rich areas across the country, Ping An, as one of the "Top Ten Selenium-rich Towns in China", has a typical plateau and pure climate, no harmful companion organisms, no pollution, no heavy metal residues, and is suitable for development and utilization. The resources have unique advantages, and at the same time enjoy the reputation of "China Plateau Pure Land Selenium-rich Area", "China Plateau Selenium-rich Health Area" and "Plateau Selenium Capital".
In recent years, Pingan District of Haidong City has continuously improved the brand effect of “plateau, green, and selenium-enriched”, and efficiently integrated the investigation and research results of selenium-enriched resources in Pingan District, and passed soil testing, selenium-enriched land grade evaluation, agricultural selenium content classification, and selenium database. Establishing selenium-enriched land archives, optimizing two concentrated contiguous selenium-enriched lands in Sanhe Town and Hongshuiquan Township, and implementing "one land, one yard", which is certified as qualified selenium-enriched land Issuing an "identity card", which has a five-year validity period and is administered nationwide.
The identification of natural selenium-enriched land has a good role in promoting the brand building and industrial development of Ping An "Plateau Selenium City", realizing the real improvement of the self-value of the land and making the ecological value more prominent.
At the same time, the natural selenium-enriched land in Ping'an District will be managed at the national level, with unified publicity and unified supervision, a stronger reputation and continuous improvement in market recognition.
Ping'an District, Haidong City, will further accurately delineate the boundaries and ownership of selenium-rich land, and establish a unified file and brand for its land. The signs will be published on the field, so as to encourage companies, cooperatives, farmers and others to participate in the selenium-rich industry to a greater extent. At the same time, expand investment promotion, introduce high-tech enterprises to settle in, further activate the selenium-enriched industry investment market, enhance the current driving force for the development of selenium-enriched industry in Ping'an District, and promote product quality and efficiency.
