Agricultural product quality safety is the hot topic in the world. From the technical view, the agricultural production management and traceability are the key measurement for insuring the quality safety. From 2005 until now, we have been investigating the information technology support for improving the management and traceability level of product quality, such as barcode, RFID, PDA/Cell Phone, MIS, electronic scale, GIS, GPS, GPRS and decision support models, etc. We have developed six techniques, four equipments and six kinds of information systems. The six techniques include ¢Ùindividual identification and coding, ¢Úbarcode generating and printing middleware, ¢Ûbarcode encryption and decryption, ¢ÜRFID middleware, ¢ÝGAP-based early warning, ¢ÞXML-based data transferring. The four equipments are ¢Ùportable real-time record-keeping equipments for agricultural production, ¢Úportable intelligent dispatching equipments for agricultural products, ¢Ûportable supervision equipments for agricultural products,¢Ücontrol equipments for agricultural product sale. Also we have developed six kinds of information systems that are ¢Ùenvironmental evaluation systems for agricultural fields, ¢Úmanagement information systems for agricultural safe production, ¢Ûwholesale market management system, ¢Ülogistics management system, ¢Ýagricultural product quality safety supervision and traceability systems and ¢Þemergency management systems for agricultural product quality. Until Nov. 2009, we have developed the management and traceability systems for aquatic products, vegetables and fruits, as well as livestock, and applied them in Beijing, Tianjin, and Guangdong, China. The application has gained significant economical, social and ecological benefits.
