Hiraizumi mushrooms are agricultural products with geographical indications.

Pingquan County in Chengde City was awarded the geographical indication certificate for the agricultural product "Pingquan Shiitake Mushroom" by the Ministry of Agriculture, effectively increasing the popularity of the Pingquan Shiitake Mushroom brand and laying the foundation for building a hometown of edible fungi.

In recent years, Pingquan has vigorously developed the circular economy of edible fungi and vigorously promoted the development of the green edible fungi industry. We continue to introduce excellent varieties from other places and develop new varieties with our own characteristics, forming a development pattern of complementary varieties such as shiitake mushrooms, slide mushrooms, black fungus, and oyster mushrooms, combining long and short cycles, and multi-mode annual production. Four scientific research institutions, including the Edible Fungi Research Institute, the Edible Fungi Research Association, and the Productivity Promotion Center, have been established, and cooperation with scientific research institutes such as the Chinese Academy of Agricultural Sciences and China Agricultural University has been strengthened. More than 10 new varieties have been introduced, researched, developed, and promoted. There are more than 20 new technologies, such as off-season mushroom cultivation, waste reuse to develop grass rot fungus, cut-free water-retaining film for shiitake mushrooms, and harmless prevention and control technology, which have greatly improved the scientific and technological content of the fungi industry. It has cultivated and created well-known brands such as "Senyuan", "Runlong", "Qiansui" and "Three Trees". Through the Edible Fungi Processing Technology Demonstration Park and the Fungi Standardized Production Base, it has radiated and driven farmers and surrounding areas, effectively increasing the penetration rate of new technologies. In 2010, 210 million bags of edible fungi were completed, including 25 million bags of shelf-type shiitake mushrooms and 75 million bags of ground-grown shiitake mushrooms.
