Scope

Scope: This document specifies the terms and definitions, environmental conditions, cultivation techniques, pest and disease control, harvesting and processing, storage, and cultivation record and archive preservation for the cultivation and initial processing of Wufeng Tianma in Hubei Province. This document is applicable to the cultivation and initial processing of Wufeng Tianma in Hubei Province. Main technical content: 3. Terms and definitions The following terms and definitions are applicable to this document. 3.1 Tianma (Gastrodia elata Bl.)
