Abstract: Cloud storage technology, through clustering applications, virtualization, distributed file systems and other functions, let a large variety of different types of network storage devices set up cooperative work, in order to alleviate the pressure of old data center storage. Many of document management and sharing of the current agricultural information platforms waste a great space, with the development of information technology,more and more agricultural enterprises need a comprehensive rural information service platform based on cloud storage technology. This paper takes cloud storage as the design foundation, on the one hand through the research data deduplication technology, puts forward a kind of repeated data file level in the client using MD5 Hash algorithm for the delete operation after the data will be stored in the cloud server method, so as to provide agricultural information platform and the internal unity of the file sharing; On the other hand, the paper uses Wecommunication protocol, with real -time, occuping less network bandwidth, and communication more efficient, completely aelopts HTML5 Web Socket based on Web communication protocol to realiz agriculture inter enterprise network business.
