Pu’er Dendrobe in Yunnan Province
Pu’er District, the largest in land area and highest in forest coverage rate in Yunnan Province, benefits from its unique geographical location. Located along the Tropic of Cancer, it receives warm air streams from the Bengal Bay, resulting in abundant rainfall, mild winters, and cool summers. These conditions create an average temperature of 18.9℃ and exceptionally high levels of negative oxygen ions, making Pu’er an ideal environment for the growth of Dendrobium candidum.
Natural Habitat and Growth
- Natural Habitat:
- Dendrobium candidum, a perennial herbaceous to epiphytic orchid, thrives in Pu’er’s semi-wet mountainous regions with altitudes around 1600 meters. It grows on rocks and absorbs nutrients from its environment, benefiting from the region’s rich biodiversity and pristine ecological conditions.
- Medical Usage:
- The stalk of Dendrobium candidum has been valued in traditional Chinese medicine for centuries. It is known for its ability to regulate digestive functions and clear internal heat. The tender parts of its stalk, when properly treated, are spirally twisted into spring-like shapes and sold as Tiepi (Iron hide) Fengdou.
Historical and Medical Significance
- Dendrobium candidum holds significant historical and medical importance in Chinese culture. Mentioned in ancient texts such as the Shennong’s Herbal Classic and Daozang, it is recognized for its ability to strengthen digestive functions and support weak internal organs. Renowned Chinese physician Li Shizhen also praised its medical benefits.
- The plant was favored by royalty in Chinese history but its natural production is rare due to the challenging environment in which it thrives. Consequently, Dendrobium candidum is now protected as a rare medicinal herb in China.
Industrial Development
- In recent years, Pu’er has actively promoted the Dendrobium candidum planting industry. Through artificial cultivation efforts, significant progress has been made, with over 11,018 acres dedicated to industrialized Dendrobium planting. Annually, this production yields approximately 2,151 tons with an output value exceeding 60 million yuan.
- To further develop the industry, Pu’er’s local government has partnered with Conba Group, signing a strategic cooperation framework agreement. The goal is to expand Dendrobium candidum planting to 2 million acres within 3 to 5 years, establishing the country’s largest industrial base for Dendrobium candidum.
Conclusion
Pu’er District’s commitment to the Dendrobium candidum industry exemplifies its dedication to leveraging its unique ecological advantages for economic development. Through sustainable cultivation practices and strategic partnerships, Pu’er aims to enhance both the local economy and the preservation of this culturally significant plant in traditional Chinese medicine.
