Abstract：Blockchain technology has the technical characteristics of information sharing，real and secure data，information and certificate traceability，smart contract and so on. There are multiple couplings between blockchain technology and circulation demand of agricultural products. Nowadaysblockchain technology has been partially applied in the circulation of agricultural products，but there are still some deficiencies，such as the low degree of application integration of the whole industrial chain，the failures of data sharing and reliability，and the difficulties of the implementation of the agricultural financing blockchain. There are some application scenarios. First，the alliance chain of agricultural products cross-border trade can improve the fairness and transparency of trade and reduce the risk of trade；and it can be jointly developed by core enterprises，industrial funds，and information technology enterprises to establish the upstream and downstream industrial synergy. Second，the alliance chain of agricultural products logistics can realize the whole process control of logistics and automatic settlement of expenses；and this mode needs to strengthen mutual trust，establish coordination and incentive mechanism within the industry，and integrate and apply various information technologies. Third，agricultural product whole life cycle tracingblockchain can realize the traceability of agricultural products from production origins to end consumers；and in order to ensure the data sharing and supervision through the whole chain，it needs to give trust to all parties in the chain through system design，and use a variety of technologiesand integrate activities online and offline to prevent any fraud. Fourth，agricultural financing blockchain，which will effectively deliver value，has the function of credit investigation and automatic fulfillment based on smart contract；and this function can effectively meet the needs of agricultural financing and reduce the cost of credit investigation；and the implementation of this application mode requires the establishment of risk control system，certification standard and technical system of selfcertification，as well as the technical business standard agreed by the financial industry，so as to realize cross- chain sharing of credit information. The implementation of specific projects of agricultural products circulation blockchain needs to plan rigorous implementation steps，including judging its applicability，carrying out blockchain training，conceiving theoretical models， looking for cooperation of internal and external resources，developing prototypes and implementation.
