Our planting base is located in Sichuan Province, China. Situated in the country's southwestern region, the area features elevated terrain (with basin elevations of 500 meters and plateau regions exceeding 3,000 meters), benefiting from a warm, humid climate and fertile soil. Sichuan has been a prominent hub for sansho cultivation since the Tang Dynasty, renowned for producing celebrated varieties such as "Hanyuan Sansho" and "Maowen Sansho," known for their long cultivation history and exceptional quality.

   The cultivation base spans extensive areas and is divided into multiple standardized planting zones. Each zone practices differentiated variety cultivation and conducts ongoing specialized research aimed at enhancing yield and quality, thereby addressing diverse customer needs.

   Our management team maintains continuous documentation of sansho tree and fruit growth, enabling scientific management through integrated data analysis. Strict adherence to standardized procedures is enforced for irrigation, fertilization, and pesticide application, with complete and accurate records of planting logs and pesticide usage history. Annual water quality testing and pesticide residue analysis are performed to ensure compliance with domestic and international food safety regulations, underscoring our commitment to establishing a production system aligned with global food safety standards.
