China News Agency, Xining, February 26 (Reporter Li Jiangning) China's Cordyceps sinensis production accounts for 98% of the world's production, while Qinghai Cordyceps sinensis accounts for more than 60% of China's production. According to incomplete statistics, the high-quality Qinghai Yushu Miscellaneous Cordyceps sinensis 2021 The annual transaction price is 40,000 yuan (RMB, the same below) to 60,000 yuan per catty, and the annual transaction is about 2 billion yuan.

In the past five years, the price of Cordyceps sinensis has continued to rise.

　　With the increasing market demand, artificial cultivation of Cordyceps sinensis gradually appeared in the public eye.

Li Yuling, director of the Cordyceps Research Office of the Grassland Research Institute of Qinghai Academy of Animal Husbandry and Veterinary Sciences, said in an interview with a reporter from China News Agency on the 26th that it is expected that by 2025, the global market demand for Cordyceps sinensis will reach 274.6 tons, which will be in short supply by then.

In recent years, artificial cultivation of Cordyceps sinensis has developed rapidly, and this technology is expected to solve the problem of market demand in the future.

　　Cordyceps sinensis has an obvious geographical monopoly. China's Cordyceps sinensis resources are mainly distributed in areas between 3,500 meters and 5,000 meters above sea level. The core production area is Zaduo County, Yushu Tibetan Autonomous Prefecture, Qinghai.

Cordyceps sinensis in this area is most famous for its brownish-yellow color, thick flesh, short and stout peduncles, and good quality.

Studies have shown that Cordyceps sinensis is rich in protein, fat, cordycepic acid and various amino acids, which can regulate human body functions, enhance immunity, enhance macrophage function, and promote the formation of antibodies, so it is called "soft gold".

The annual output of Cordyceps sinensis in Qinghai Province ranks first in China. In 2020, the province's Cordyceps sinensis export value was 47.295 million yuan, ranking first in China.

　　"From the perspective of the future industrial development of Cordyceps sinensis, artificial cultivation of Cordyceps sinensis is a development trend, but this technology must be based on the protection of ecology and the market." Li Yuling said.

　　The reporter learned that the main chemical composition of artificially cultivated Cordyceps sinensis fermented powder is similar to that of Cordyceps sinensis, and the price is relatively low, which has been gradually accepted and recognized by the public.

In recent years, a large number of studies have found that Cordyceps sinensis fermented powder can be used to treat a variety of respiratory diseases.

Cordyceps fermented products have entered the US and European markets, including Cordyceps capsules and oral liquids, which can enhance sexual function and immunity.

　　Li Yuling believes that artificially cultivated Cordyceps must be controlled by technology. When the output of natural Cordyceps is low, the output of artificially cultivated Cordyceps can be increased; when the output of natural Cordyceps is large, the output of artificially cultivated Cordyceps should be tightened.

"Through artificial control and standard formulation, priority should be given to the protection of natural Cordyceps sinensis resources. Artificial is the artificial price, and natural is the natural price. There must be a gap between the different prices of different products, from the output, standards, prices and sales channels. Control, try not to affect the market order of the Cordyceps sinensis grassland."

　　In addition, the reporter learned that the current industrialization of artificial cultivation of Cordyceps sinensis depends on the continuous retrieval of soil and rhizomes of Polygonaceae from the production areas of Cordyceps sinensis.

With the continuous expansion of the production scale, more soil, plants and high-quality Cordyceps sinensis germplasm resources are needed in the production area, which will inevitably lead to ecological damage in the origin.

　　Li Yuling said: "Artificial cultivation of Cordyceps sinensis must ensure the use of strains and insect sources in the origin, so that the healthy development of the Cordyceps sinensis industry can be achieved."

　　At present, Li Yuling's team has taken the lead in solving the core problems of artificial breeding of Cordyceps sinensis, such as the selection of dominant host insects and the cultivation of high infection rate strains.

　　Li Yuling said that at present, artificial cultivation of Cordyceps sinensis in Qinghai adopts the "lab + field" model. In the laboratory, the worms are cultivated to become the worms that are about to become Cordyceps, and then they are cultivated as "seeds" to grow in the production area.

"First of all, this method will not cause any damage to the ecology. Second, in addition to the income from mining natural Cordyceps, farmers and herdsmen in the origin can also obtain another income by participating in the early cultivation and later planting. "(over)
