Coding system, traceability and safety production of tea based on WebGIS

A reasonable coding system of tea production places is the foundation for safety production and traceability of tea. A coding system of tea product places was proposed, which was based on environmental assessment, soil properties and distributing of tea planting. And the way of combing regional code with parcel code was adopted. According to coding system, the production, processing and circulation of tea were joined together with WebGIS technology, which integrated tea production and circulation information with spatial data of tea production places. Finally, an archetypal management information system “From Farm to Table” was developed. Quality safety production, traceability of tea products and circulation information were achieved reliably in Ningbo tea as a case study. The research can also provide scientific reference and basis for code design and safety production and traceability of other farm products.
