| The article in order to study the fertilizer quantity to maize,which was influenced by production level of different areas and nutrition of soil,we developed the maize Measurement and Fertilization Expert System by combining the artificial intelligence techniques,GPS and GIS,with the fertilization for break,taking the mathematics model of nutrient equilibrium as the core,and adopting the object-oriented programming technology.The system mainly resolves the two problems of yield prediction and precise fertilization and ultimately print for the user the consultation sheet of maize precise fertilization,including predicted yield,variety,fertilizer quantity and the situation of benefit analysis.The practice result has showed that the application of this system could reduce cost,make present increase yield and benefit,and realize low cost but high production.Combining .NET program design technique and expert system technology, the system was developed by making use of the recently spatial data in JiLin province. It realized to integrate spatial information, intelligent decision and network browser in the system. The system not only resulted in spatial information opening and network resource be sharing, but also made users inquire the data what they want to and offered them a science, reasonable fertilizer plans. The system can help users improve economic and social benefit. |
