Whole Design On Rice Ecological Balanced Fertilization Decision Support System Of Heilongjiang Province And Realization Of Part Module Function

The decision support system for rice ecological balanced fertilization is based on the theory of ecological balanced Model, Using the technical system of the utility and new advanced technology, achieving the new compute-fertilization-system about the ecological balanced fertilizer. The model of rice ecological balanced fertilization is based on the conservation of mass and the relation of transmuting of the availability nutrition, the balanced fertilization is the best combination of fertilizer input which can meet the needs of high quantity, low investment, none-pollution, and so on. The technology system includes: changing the qualities of fertilization; improving the soil condition of root region, and fertilize region, reducing the input of the fertilization, reuse the nutrient and cycle technology; the way of testing the ecological balanced fertilization, the way of testing the special fertilization formula; the way of fast testing the effective nutrient, forecast system of the fertilization, management system, and so on.Using the expert's professional knowledge and the information technology develops the design for the system of rice ecological balanced fertilization. Summarize the fertilizing investigation result scientifically and highly integrating at one of the region in Heilongjiang province. And expressed by compute, namely, organizing the regional fertilizer technology according to a certainty rule then put it into compute, thereby building up a decision support system that can assistant people to work, this system has sever virtues, such as, it can adjust measures to local conditions, technology optimization and integration, applying conveniently, and so on. Hereby, it has an abroad extending and applying future.The design of the decision support system for rice ecological balanced fertilization keeps to the life-period method of the software engineering, be designed phases, The summary design project of the whole system was brought forward by using the configurable analyses method, during decision support system design and realization, first analyze the flow of rice ecological balanced fertilization, and plot the database stream chart of rice ecological balanced fertilization, then adopt the data stream analysis method to bring forward sub-system function configuration table. At last, using OO(object oriented) program tool like the VB6.0, ACCESS2000, MULTIMEDIA, etc. To realize the function of ecological balanced fertilization system. So that I design five modules, considering the characteristic of operational research, not to estimate every module isolated, but integrate to estimate all modules that the system includes take the reciprocal modules as a whole, take into account the collectivity benefit to seek the optimization project.The system mainly include the learning function, the fertilization quantity forecasting function, input and output function, Stat function, financing balanced function, data update function. The system integrates the compute with the agronomy. It has the characteristic ofhigh technology, comprehensive function, configuration criterion, interface friendly, easily studying and utility. It has great value in theory and utility for the development of the intellectualize agriculture information technology of the Heilongjiang province.Candidate: Zhou BaopingSpeciality.
