Development Of Maize Precision Fertilizer Expert System In JinLin Province

According to the nowadays production conditions of JinLin province, The effective system was developed by utilizing the knowledge of agricultural production, computer science and internet technology and so on in the paper. The design of the system was made the best of the life-period method of the software engineering, designed phase, and the summary design project of the whole system was brought forward by using the configurable analyses method. During designing and realization of the system, the author collected some materials for the system and communicated with domain experts on the knowledge of maize fertilizer, and plotted the database stream char of the expert system, then created sub-function chart by using the analysis method of the database stream. To realize the functions of the maize precision fertilizer expert system, OO(object oriented)program design language tool like the Java,Access2003, multimedia technology .etc were used in the system. Considering the characteristic of operational research, the author designed six function modules, which were not been isolated one another, but integrated to all modules. The system mainly included the recommend fertilizer, nutrition diagnosis, spatial inquire, system management and so on. Every function modules included some sub-function modules.The nutrient balance method was mainly researched on maize fertilizer in the old researches, and most of them stay the level of theory and mechanism without concrete, timely and system research. Combining some new technology and new method in agricultural research is a new trend in future. In order to reach the aim, the author combined theory model and quantitative research and developed the system. It will inject a kind of new action and energy into maize fertilizer research. There were four innovations in the system like the followings. Author established knowledge base and complex database by summing up some information of maize precision fertilizer. The system was helpful to increase yields, improved social and economic benefit. An opening database interface was established, the research mainly improved and strengthened on the methods of creating database. The old database is...
