　　Gastrodia elata is a precious medicinal herb known for its effects in calming the liver and suppressing wind, dispelling wind to relieve pain, lowering blood pressure, and preventing cardiovascular diseases. Gastrodia elata thrives in humid conditions but does not tolerate high temperatures, making mountain slopes at elevations above 600 meters the most suitable for cultivation. The nine villages centered around Zhangguanghe in Sanhekou Town form the main production area for semi-wild Gastrodia elata cultivation, with an average elevation of over 800 meters, an annual average temperature of 16°C, 1600–2513 hours of sunshine annually, abundant sunlight, and ample rainfall—all ideal conditions for Gastrodia elata growth. The natural climate endows Zhangguanghe Gastrodia elata with its premium qualities: large size, plump flesh, yellowish-white color, firm texture, and no hollow core.

　　Over the years, the Sanhekou Town government has vigorously promoted the development of the “Zhangguanghe Gastrodia elata” specialty base. In 2016, the Zhangguanghe Gastrodia elata Industry Association and Gastrodia elata planting cooperatives were established. These initiatives integrate the development of specialty industries with targeted poverty alleviation efforts, actively connecting cooperatives with impoverished households. Free seedlings and planting technical guidance are provided, and products are purchased at protected prices. The town currently has over 5,000 farming households, more than 20,000 farmers engaged in the industry, over 80,000 acres of cultivated land, an annual output of approximately 5 million jin (2.5 million kg), and an output value exceeding 70 million yuan. Products are sold in major cities and provinces such as Hubei, Anhui, and Henan, and are also exported to Singapore and Hong Kong.
