Study And Establishment Of Intelligent Decision Support System For Rapeseed Production

For solving the mixed-up problems in the production of both high quality and ordinary rapeseed in AnHui Province, this paper illustrates that the establishment and advantage of a new designed intelligent decision support expert system for the cultivation and administration of high quality rapeseed in the province . This system was designed with both the base of experts' knowledge and years of experience in rapeseed production and computer soft ware ,and the reference to the XiongFeng Intelligent Expert System Developing Stage AIP 1.0, also the utilization of knowledge engineering and information technology.The organization and structure of this designed system includes six main pacts: knowledge base, data bank, model base, human computer interface, explanation unit, and reasoning unit. The knowledge base and reasoning unit are mutually independent and with considerably strong capacity of extension; the module structure enhances the system to be further extension and more perfect only by the extension and perfection of the specific module. Furthermore, this system, synthetically integrated with agricultural expert system, decision support system, as well as multimedia technology, is not only objective, imaginable, and friendly for human computer interface, but also simple to handle operate, easy to learn and understand. This system takes WINDOWS as its apply stage. Synthetical use of the mechanics of reasoning, prediction, and explanation is of meaning for serving and advising the customers to realize the decision of synthetical cultivation and administration of the super quality rapeseed. The function of this system possesses the following three modules:Qualifying decision prior to seedingThis system is helpful to select proper rape variety with the condition of regional cropping system, soil type, and cultivation style, to determine right seeding time according to the cultivation region, cropping system and cultivation custom, to arrange suitable thickness referring to the cultivation method, soil fertilizer, and transplanting time, and to choose the favourable variety of fertilizer and decide adequate amount with the consideration of target yield and yearly rainfall.Cultivation and management while productionThese measures include the techniques for both direct and transplanting, rapeseed varieties, synthetical prevention diagnosis, and treatments for the damage of concerned insects, diseases and weeds, also for the physiological diseases. These measures involve the techniques of irrigation and management of super quality rapeseed varieties as well.Yield prediction and economical beneficial analysisThese can be done by the calculation of the cost for labor, seeds, fertilizer, pesticide, agricultural machine, irrigation, etc., and the output of yield and market price, so as to have the understanding of total cost, total yield, and the net profit. This designed system, which has been checked and proved its precise and steady characters, its friendly relation of human computer interface, its visual and simple and easy for operating, achieves, its original design requirements, and is super and directed comparing to other systems related.
