摘要
结合养分平衡施肥决策模型,利用面向对象、GIS组件和网络数据库技术构建了基于GIS的县域小麦测土配方施肥决策系统,该系统已成功应用于河南滑县小麦生产,为推行科学测土配方施肥提供技术支撑.
Adopting nutrient equilibrium fertilization decision-making model, the paper construsted a GIS-based county testing soil for wheat formulated fertilization decision-making system by using objectoriented, GIS components and network database technology, which had been successfully used in the production of wheat in Huaxian Country in Henan, providing technical support for the implementation of scientific testing soil and formulated fertilization.
