| Abstract: | Based on knowledge engineering and PAID, the fruit trees' expert systems for diagnosis, pre-vention 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 differentiation between diseases and pests was set up. Diseases di-agnosis, prevention and control decision was divided into infectious and noninfectious diseases. Diagno-sis, prevention and control decision of nutition drbieient were based on the combination of morphological symptom and leayes nutrition analysis. Knowledge rules were edited by template. The prospect of appli-cation foreground on the fruit trees' expert system was also discussed. |
