Studies On Culture Management Expert System Of Tomato In Solar Greenhouse In Weifang

Tomato is one of the main crops cultivated in solar greenhouse in Weifang, but the increase of Tomato's yield and quality is limited by the lack of the experienced experts. As for the solution of this contradiction, Cultivation management Expert system of Tomato(CMEST)under solar greenhouse circumstances in Weifang is studied in this article.CMEST under solar greenhouse circumstances in Weifang, an intelligent computer system, is the second research that bases on the agricultural experts' systemPAID3.0 ( Platform for Agricultural Intelligence-system Development) provided by Agriculture Information Technique Research Center of Peking (AITRCP) . The system is designed by applying artificial intelligence principle and adapts to all object, adopting the knowledge of "rule-frame and rule-body" model to interpret strategies and the concluding mechanism featuring mixed and controlling. The system includes managing measures of high production, identification of plant diseases and pests , symptoms and the comprehensive means of prevention and management for tomato cultivated under solar greenhouse circumstances.In the process of studying the system, We draw the following conclusions.1 .CMEST under solar greenhouse circumstances basing on PAID3.0 is colorful in details and can mainly satisfy the productions requirement.2.PAID3.0 designed by Agriculture information Technique Research Center of Peking (AITRCP) reduces the complexity of the system that is characteristic of network, mold, piece, intelligence and optical capability, meanwhile, it increases many capacities of the system, such as, reusable, repairable and expansible abilities.3.The expressing means of the system have the features of nature, consistency and integration. It increases the expressing ability of knowledge and strengthens concluding functions.
