Research On The Tool Of Agricultural Expeirt System And Its Application In Apple Orchard Management

In view of the diversity and complexity of agricultural problems and the imbalance of ag ricultural development in china,agricultural expert system is irreplaceable in the development of agricultural modernization.Agricultural expert systems can be applied to problems only ag ricultural experts can solve,effectively guide farmers to farm and breed scientifically to achie ve sustained,high quality,high yield and efficient development of agriculture.However,som e issues like the lack of general expert system development platform and non-editable knowle dge base restrict the popularization and application of expert system in agriculture.Therefore,research and development of a general agricultural expert system development tool has theor etical significance and application promotion value.By use of the principle of expert system and knowledge system,this study constructed a general framework of agricultural expert system,established a simple and easy-to-use develop ment tool for agriculture expert system,and summarized the apple orchard management know ledge and experience,collected data to build related models,and ultimately built a set of appl e orchard management expert system.Specific research contents and results are as follows:(1)General agricultural expert system development tool.By analyzing the functional ch aracteristics in making expert system platform and the structure of the generated expert syste m,we research the general framework of agricultural expert system;Based on the analysis of the structure of agricultural expert system,it was attributed to three patterns of decision condit ion chain of quantitative and qualitative decision service,which are "options","input" and "op tion + input parameters" respectively.According to general requirements and design principle s,we made design for the system architecture,function,and logic,and finally completed the d evelopment of the general agricultural expert system development tool.(2)Apple orchard management knowledge and model.We studied the construction strate gy,cultivation management,variety evaluation problem by using fuzzy comprehensive evalua tion,cluster analysis and other mathematical methods,and completed the evaluation models of apple orchard construction and varieties,and summarized the apple orchard management of t echnical knowledge.According to the indexes of soil and meteorology,we completed the eval uation of construction conditions,which provided the basis for matching tree species with site of apple trees.Combining with meteorological data of cities around Shandong Province,we gave some suggestions for suitable varieties.According to six indexes of cold tolerance,droug ht resistance,flood resistance,salt and alkaline tolerance,high yield and high quality,we com pleted the evaluation of cultivated varieties,which will have practical value for the breeding a nd popularization of apple varieties.(3)Apple orchard management expert system.We imported apple orchard management k nowledge and related models into the agricultural expert system development platform to com plete the development of apple orchard management expert system.Application of this syste m can effectively promote the scientific and quantitative production management of apple orc hard,meet the needs of the expert consultation at anytime and anywhere,solve the problems e ncountered in production management more conveniently,to achieve high quality,low yield a nd low consumption of apples,improve farmers economic benefits.
