1970, the artificial cultivation of Grifola frondosa was the first in Japan, and the output increased year by year. In recent years, the output has exceeded 10000 tons. Due to the shortage of products, Japanese also imported from China. In recent ten years, some scientific research units and producers in Zhejiang, Hebei, Beijing, Sichuan, Yunnan, Fujian, Shanghai, Heilongjiang and other places have introduced and domesticated Grifola frondosa, and achieved large-scale production in Qianxi, Hebei and Qingyuan, Zhejiang. From 65438 to 0997, the national output of Grifola frondosa reached 1 10,000 tons. Products are not only exported to Japan, but also to the United States, South Korea and other places. However, due to the quality problems such as product flavor and impurities, it once affected the market expansion.

The technical research on improving the quality of Grifola frondosa began on 1996 in Qianxi County, Hebei Province. In 2002, it took technicians six years to tackle key problems continuously and select excellent varieties suitable for specialized production. The preservation technology and processing technology of medicinal raw materials were studied and passed the expert appraisal. In 2003, "Development of pollution-free standardized production technology of Grifola frondosa (chestnut mushroom)" was listed as a national spark project. In the process of large-scale implementation of the project, the technology is further mature, which not only overcomes the difficulty of facility cultivation, but also realizes the mushroom production of Grifola frondosa all year round, and the shelf life of closed preservation technology exceeds 30 days. In addition, it has also implemented specialized production modes such as an annual output of 400,000 kilograms and a daily output of 400 kilograms. The products have entered the fresh vegetable market and stabilized the market supply. The quality of the product has been tested by the Vegetable Quality Testing Center of the Ministry of Agriculture, which conforms to the national edible fungus product standard and the Grifola frondosa standard of the Ministry of Agriculture. The indicators of harmful substances such as arsenic, mercury, lead and pesticide residues are less than 1% of the national allowable indicators, which realizes the standardized and pollution-free production technology of Grifola frondosa.

At present, the production scale of more than 2,000 tons of fresh Grifola frondosa has been formed, and only a few counties such as Qianxi in Hebei and Qingyuan in Zhejiang sell their Grifola frondosa products to domestic and foreign markets. A large number of branches pruned from chestnut trees in Qianxi County become the main raw materials for artificial cultivation of Grifola frondosa. In recent years, through the research and exploration of scientific and technological personnel and mushroom farmers in Qianxi and Qingyuan, some new measures have been continuously introduced, and the production of Grifola frondosa has gradually developed towards mechanization and semi-mechanization. Through the implementation of product preservation processing technology, the production management efficiency has been improved by more than 2 ~ 3 times, and most large manufacturers have relatively sound production equipment. The producers all adopt advanced cultivation modes such as micro-spraying and double shed, and the output, quality and economic benefits of the products have been reliably guaranteed and improved. At present, Grifola frondosa is still a new variety in many areas. The national output is less than 20,000 tons, and the development scale is far from the domestic and international market demand. It is still necessary to develop, popularize and popularize.

Grifola frondosa polysaccharide is the main functional component of Grifola frondosa. The extraction and utilization of Grifola frondosa polysaccharide is a new industry, which has become the most effective extension industry for cultivating Grifola frondosa and has been widely studied and developed at home and abroad. It is not only used in medicine, but also provides raw materials for preparing medicinal and refined polysaccharide (D powder), and can also be used as food additives in food.
