Abstract:

Based on the agricultural geographical survey data of the Betel Nut Garden in Wanning City, Hainan Province at a scale of 1:10000, the betel nut weighted data of Wanning and fresh selenium-rich betel nut standards, the pilot certification of the place of origin of Wanning selenium-rich betel nuts is conducted, and the technical approaches for certifying the place of origin of selenium-rich agricultural products are summarized. These certification approaches include document preparation, patch assignment commenting, geochemical assessment of soil quality, geochemical assessment of agricultural product quality, the certification of place of origin of selenium-rich agricultural products, the manufacturing and issuance of certificate of origin, etc. It is found that the technical approaches for certifying the place of origin of selenium-rich agricultural products are scientific, concise and ready to be widely used, and could help to explore new fields in agricultural geology and are of active demonstration effects, the application of these approaches could yield good social and economic benefits.
