浙江省蔬菜主要病虫诊治咨询系统的初步研究

Preliminary research on consultation system for diagnosing and controlling vegetable pests in Zhejiang province

基于用户需求分析,运用软件工程、数据库和多媒体技术,模拟领域专家推理机制,综合集成了35个蔬菜种类的100多种病害、50多种害虫的相关资料,构建了浙江省蔬菜重大病虫诊治咨询系统。系统采用模块化设计思想,由推理机、知识库、系统维护、用户界面等组成,其中知识库与推理机是系统的核心部分。按功能把系统构成分为诊治决策咨询、病虫信息咨询、综合治理咨询、安全生产咨询、科学用药咨询与系统维护管理等6个子系统。并简要讨论了该系统的设计思想与方法、结构与功能、应用前景和发展方向。

As people's living standard improving and China joined the World Trade Organization, safety and quality of vegetables have become the most basic demands for vast consumers. However, technical instructions about pest identification and techniques for integrated pest management have not be transferred to the farmers in time, which resulting in the overuse of pesticides and the high pesticide residue in vegetable. Based on the previous knowledge and experience, a preliminary computer system, named Consultation System for Diagnosing & Controlling(CSDC)for Vegetable Pests in Zhejiang province, was developed. The computer system was designed based on the information from potential users, and extension staff and farmer. The source knowledge derived from literature, experts, and field experiments. The image of pests and symptoms were acquired by SONY F707, and edited using ACDSee 5.0, Photoshop 7.0 and HyperSnap-DX5.0 , then saved with the format of JPG. The database management system-VFP6.0 was used to construct the systems, which consists of rule database, fact database and picture database etc. The CSDC in Zhejiang Province consists of as follows: subsystem for diagnosis and decision-making, subsystem for inquiring information, subsystem for Integrated Pest Management, subsystem for pesticide application, subsystem for food safety, subsystem for system maintenance. Finally, potential application prospect and development direction of CSDC were discussed.
