Based On The Net Framework Rice Expert System Design And Implementation

The thesis mainly discussed the design and realization of expert system. It applied to rice growing and production process for improving paddy cultivation in cold region, which combined intelligence technology, NET framework, database technology, network technology and the leaf age diagnosis technique of high-yield rice in cold region.The building of system database and knowledge database and realization of inference engine was the core work in rice expert system. We exploited the rice cultivation expert system of rice production and management process in early, middle and later stage, which based on the abundant investigation and compare of the expert system of crop production and management. Firstly, we put forward the framework model of rice expert that was based on leaf age diagnosis technique, by collecting and organization information. Secondly, we designed the function module and established the basic databases including expert knowledge database, basic circus of rice field, basic soil information, rice varieties, main disease pest and weed in rice and weather information.The rice expert system has the characteristics of flexible and easy to use.
