The Design And Realization On Soybean Intelligent Decision Support System Of Balanced Fertilization In Heilongjiang Province

Decision Support System of soybean fertilizing is the synthesis system of model technology and the expert experience. There are database system, knowledge library system, model system, inducing equipment, man-machine contact surface and system servicing procedure and so on in structure. In order to help the peasant household to draw up the productive plan, especially helping the peasants fertilizing rationally, choosing the appropriate fertilizer, cultivating soil fertility, choosing the seeds, the determination of different time which is suitable to apply fertilizer, the reasonable density as well as the field management measure. During the soybean grow, the sickness, the insect, the grass evil will have been carried on the diagnosis, in order to confirm whether carries on preventing or controlling and the application method of preventing time, the dosage-form, the dosage and methods.The design of soybean decision-making consultation system follows the life cycle standard of software engineering. The system will be exploited in steps and the summary is brought up by using object-oriented programming (OOP) method..Appling multimedia technology, expert system, database, multi- ES cooperation and object-oriented programming, Decision Support System of soybean fertilizing take authoritative soybean expert's knowledge, the tradition and the new mature technical achievement, used in the mathematical model and farmer's scientific farming experience into organically integrating. Adopted a method of suited the Heilongjiang Province land characteristic, the system is developed. This system still mentioned the high production cultivation pattern, sickness and insect and grass diagnosis, the variety plot delimits with the choice, the rate of prediction subsystem. Decision Support System of soybean fertilizing realizes using the writing, the sound, the graph, the image and so on the many kinds of media. Providing for the peasants always computer expert in the side, it can instruct peasants scientific farming anytime and anywhere.
