Dacun Black Fungus

Dacun Black Fungus is a geographical indication agricultural product.

　　Dacun Town in Jiaonan is renowned as the "Hometown of Edible Fungi in Qingdao." In 2011, "Dacun Black Fungus" was certified as a National Geographical Indication product. The Dacun Black Fungus Premium Demonstration Park is located in Hebei Village, Dacun Town, covering an area of 600 mu, with the first phase spanning over 200 mu. The total investment exceeds 7 million yuan, and currently over 1 million yuan has been invested. The project integrates breeding, spawn stick production, and woodland cultivation, adopting a "company + farmer" production model. Farmers can purchase pre-fermented spawn sticks from the company and directly produce them on their own land, eliminating concerns about technical issues. After harvest, the demonstration park also takes responsibility for purchasing the finished black fungus, helping farmers secure sales channels.
