Optimization Strategies for Traceability of Agricultural Products Based on QR Code Anti-counterfeitingTaking Jinhua Characteristic Agricultural Products as an Example

Agricultural products from farmland to table is not only process of physical manufacturing and provision, but also process of information production and transmission．Taking Jinhua characteristic agricultural products as main object, through field investigation and analysis of Jinhua production base, it was concluded that, anti-counterfeiting and encrypted QR code for traceability met needs of local agricultural products traceability．Digitizing and online product qualification certificate could achieve data visualization of entire production process, making it convenient for consumers to query and trace．Current research status of traditional agricultural products traceability was summarized, needs and advantages of digital agricultural products whole-process traceability were analyzed from four links of production, packaging, transportation and sales of agricultural products, and development countermeasures were proposed from several aspects such as QR code anti-counterfeiting construction, electronic certification, meteorological prediction and back-office construction of traceability, in order to strengthen quality control of every link of agricultural products．
