Construction And Application Of Agricultural Expert System

Agricultural Expert System is an important tool during the development of agricultural information. As agriculture becomes more and more important in the national economy, the high-end and information technological agricultural industry is being developed, and the agricultural expert system is used to guide the agricultural production management in the aid of computers with high efficiency, images, sounds and other intuitive media.This dissertation focuses on the application of the agricultural expert system to the diagnosis of crop diseases and insect pests. The theory of agricultural expert system has been relatively mature, and been researched in all areas of agriculture theoretically, but the agricultural expert system has not been applied to the practical agricultural productions extensively. Due to the limitation of the agricultural expert system itself, it is impossible for the system to cover all areas and all segments of experts, so the existing agricultural expert system is secondary-developed to form a special system for Lanzhou City and it is necessary to popularize the system to Maximize the effectiveness of the system.In this dissertation, the information management system is applied to the agricultural expert system. Firstly, the research status and development background of agricultural expert system is summarized and the shortcomings of existing agriculture expert system, such as low efficiency of the operational management mode, too theoretical, etc., are pointed out. Then, the localization transformation of the agricultural expert system for Lanzhou City is put forward, that is, to structure a new system by integrating the crop remote video diagnosis system and Web Query System into the existing agriculture expert system. The description of the new system, including the scheme of system composition, operational mode, the scheme of implementations, the current running state of the system, and the selection and management of each diagnostic point, is followed.Finally, the case that the developed agricultural pest control diagnostic system was used in the diagnosis process of agricultural stores in Yuzhong county of Lanzhou City is introduced, the superior and inadequacy during the diagnosis process is illustrated, and the solution to the disadvantages is put forward.
