摘要
基于知识工程方法,采用农业专家系统开发平台PAID,开发了肥城桃、设施桃、设施杏等果树的病虫害诊断与防治专家系统。阐述了该系统知识库的构建策略:知识获取立足本地化、特色化原则和无公害标准化生产规范; 知识库结构设计中建立病虫害分辨决策;病害诊断与防治决策分为侵染性病害和非侵染性病害两部分;营养失调症诊断与防治决策中建立形态诊断和叶片养分诊断决策相互配合使用的机制;利用模板编辑知识规则。最后,对果树专家系统应用前景进行了展望。
Based on knowledge engineering and PAID, the fruit trees＇ expert systems for diagnosis, prevention and control of disease and pest were studied. The construction method of the knowledge database was introduced：knowledge acquirement was based on localization, specialization and standardization. In the design of its structure,decision for differentiatioh between diseases and pests was set up. Diseases diagnosis, prevention and control decision was divided into infectious and noninfectious diseases. Diagnosis, prevention and control decision of nutition drbieient were based on the combination of morphological symptom and leaves nutrition analysis. Knowledge rules were edited by template. The prospect of application foreground on the fruit trees＇ expert system was also discussed.
