Design And Implementation Of Soil Testing And Formulated Fertilization Expert Decision System

Soil testing and formulated fertilization technology is based on the information of soil nutrition. It computes detailed fertilization information, according to regular needs, soil feed rate and fertilizer response, etc, and the use of the computer agricultural experts system to promote soil testing and fertilization technology has become effective measure to solve current problems in agricultural production.The development of soil testing and formulated fertilization expert decision system is based on the date of agricultural experts information, and takes the newest soil testing and fertilization technology as the core. It also connects.NET, database technology and agricultural experts system, to realize the agricultural experts system featured by information management, reasoning decision-making and parameter calculation. This system has convenient information management function, and provides many scientific planting and decision-making programs, which can help farmers reduce the cost of planting, improve utilization rate of nutrition and achieve better economic benefits.This thesis is focused on the analysis of demand and has finished the design of structure and function in this system. SQL Server 2008 is used in this system as the backend database, which finishes the construction of comprehensive database and knowledge base. And the fertilization model is built through the analysis of calculation model and related parameters in soil testing and fertilization technology. According to its features, reasoning mechanism and basic process of decision-making are designed. Using Visual Studio 2010 as the development platform, language choice C++ can be developed and the function of soil testing and fertilization experts? decision making system can be designed. The system can realize convenient data management, and decide appropriate crops, rational fertilizer and detailed fertilization methods, according to soil nutrition information.User rights allotment, or access control policy and database maintenance, is built through the specific functions of the system. And the function of database maintenance is achieved by using the management of user rights and connecting the import and export related database tables. For the hardware, the GPRS wireless transmission module is developed, which is Convenient for computers and testing equipment, or the data communication among the users? mobile phones.
