Research And Implementation Of Expert System Based On Tomato Growth Analysis And Diagnosis

With the rapid development of computer network and database technology, as well as Application in the process of agricultural production, agricultural information technology plays in a more and more important role in agricultural production, which promotes the industrialization of Agriculture. China is an agricultural country. With the entry of WTO and agricultural modernization, China is the major producing and exporting countries of tomato in the world. However, most Chinese growers mainly depend on personal experience to produce tomato at present, which can’t make preventable diseases and pests or efficient growth. Therefore, this paper designed expert system based on tomato growth analysis to help growers diagnose presowing environment, variety choice, dieases and muturity. Meanwhile, growers also can query exerpt knowledge, exchange the interaction with experts, and browse tomato Planting Technique so as to provide with prevention treatment for growers.The system has been implemented tomato growth analysis and diagnosis by agricultural expert system. The database, My SQL is to save all kinds of information in this system. At the same time, the internet makes sure of transferring information, and the web server is to perform operation and maintenance.The system can diagnose diseases and pests. Through the judgment of tomato, farmers can take the way of man-machine to solve every growth problem they meet. Take the diagnosis diseases as an example, growers choose the disease place and the disease symptom, when they find the symptom the disease they meet, they can get to know what kind of disease the tomato got.The system can make prediction. The new module is composed of knowledge description, certain values and the judgment. The contribution of forward reasoning and case makes prediction practical.The system can also make tomato process analysis. When growers meet kinds of problems, such as disease symptom, by way of input, query, update and analysis, they can get how to heal the diseases and understand the symptom.The system has been used forward reasoning and has built experty knowledge, rules and preventsion measures, which has been intelligent diagnosis. The system is involved with software and agriculture to serve for the students in college to plant tomato. The system can be popularized in local region and convenient for the farmers to consult and access so as to help farmers in real-time online.
