Research And Realization Of Soil Testing And Fertilizer Recommendation Expert System

Agriculture is the primary industry,it also is the foundation of our national economic construction and development,while is the guarantee of national security and social stability.In a narrow sense,agriculture is a sector,which regards arable land as production object,and is an industry,through the cultivation of crop products to produce food and industrial raw materials.Therefore,improving the output of agricultural products is a basic problem of agricultural production.As the main means of increasing crop yield,fertilization plays an important role in ensuring the safety of agricultural products.However,for a long time,in the life of agricultural production and living,the phenomenon of blind and chaos application of fertilizer has been existed.It not only causes the waste of fertilizer,but also leads to the decline in the quality of agricultural production and environmental pollution.What’s more,it has seriously disrupted the stability and improvement of agricultural productivity.The technology of soil testing and formulated fertilization aimed at the above problems is proposed,after years of study and practice by the domestic and foreign experts and scholars.Soil testing and fertilizer application technology is the use of modern agricultural research results of Fertilization Technology.According to the amount of fertilizer,crop soil fertility and fertilizer effect,the technology propose the fertilizer solution of nitrogen phosphorus and potassium fertilizer and trace elements,based on soil testing and field experiment.The technology can give full play to the potential of arable land,to achieve high quality and high yield of crops,while to save land resources,to protect the ecological environment of agriculture,and it is of great significance in accelerating the development of modern agriculture.With the development of precision agriculture,computer technology has been applied more and more to agricultural production.Agricultural expert system has become a research hotspot.Fertilization expert system is an application of agricultural expert system in agricultural production.The application of fertilization expert system can be used to store and protect valuable knowledge in the long-term production practice,but also to play a greater role in production practice.Based on this,the project designs the research programme through learning theoretical knowledge on the basis of understanding research objectives and research status.The results of soil nutrient testing of Linqu County,Weifang City,Shandong province were obtained through the collection,preparation,detection and statistics of soil samples.The relationship between soil nutrient test value and soil nutrient correction coefficient,crop unit yield nutrient absorption amount and fertilizer use efficiency were obtained through field experiment of fertilizer effect and field experiment of fertilizer use efficiency.A mathematical model of soil testing and fertilizer application was established on the basis of the study of soil testing and formulated fertilization technology,and reading a large amount of material at home and abroad.Based on the above work,the project completed soil testing and fertilization expert system using precision agriculture technology and database technology through data collation,compiling and debugging of the software code,and design and development of the system database.The expert system mainly includes the functions,such as user information statistics,block information query,fertilizer recommendation,the fertilization guidance and so on,which can also provide users with accurate fertilization formula query and print.Finally,carry out guidance for actual production and life in the fertilizer machine.The system has friendly interface,simple operation,strong practicability,and can conveniently provide scientific fertilization guidance convenient for farmers,is the effective platform to accelerate the popularization and application of measuring fertilization technique,has broad market demand and prospects.
