Abstract. In order to solve the problems of low efficiency and backward methods in the agro-technical extension activities, this paper designed an agrotechnical extension information system based on cloud storage technology. This paper studied the key technologies, such as cloud storage service engine, cloud storage management node and cloud storage data node and designed the overall architecture of the agro-technical extension information system based on cloud storage technology. The application results demonstrate that this system has significantly improved the agro-technical extension service levels and cloud storage can greatly improve data storage capacity of the agricultural extension information system. Keywords: cloud storage, agro-technical extension, information system.

Introduction
Under the condition of much people in little land and the shortage of land resource, the fundamental way to ensure national food security is how to convert the achievements in scientific research into productive forces and the key lies in how to innovative grass-root agro-technical extension. Currently, the main problems in grassroot agro-technical extension system are as follows [1]: First, the means and methods of agricultural extension need innovation urgently, "one mouth with two legs" promotion model is still the mainstream; Second, the management of agro-technical extension needs to be improved, how to evaluate the effectiveness of the extension is also very difficult; Third, technicians need to raise their quality and ability, overall aging, outdated knowledge, single profession are big problems among the technicians, they need to raise their quality and ability immediately. The agro-technical extension information service system based on modern information technology, providing agro-technical consulting, expert consultation, training services, extension logs, dynamic scheduling and other functions, can effectively solve the problems which farmers encountered during the agriculture production and management activity[1]. However, the amount of user data in the agro-technical extension information system is large with a rapid data growth. D. Li and Y.

The traditional storage solutions on mass data storage and resources dynamically expanding have certain difficulties. Cloud storage, which is based on virtualization, distributed, clustering technology, provides consistent access to data storage and business functions through unified management and scheduling over the various types of network storage devices[2]. Generally speaking, cloud storage has the following characteristics [3]:
