测土配方施肥辅助决策平台的研究与应用陈天恩 赵春江 陈立平 陈 红


  摘 要:为了解决目前我国测土配方施肥软件难以推广的问题,采用面向构件技术设计了测土配方施肥辅助决策技术体系,并着重对其构件体系进行阐述;对测土配方施肥的作业流程进行了业务单元的划分,并将划分结果映射为相应的业务构件;在此基础上,给出了按需搭建构件化测土配方施肥辅助决策系统的方法;最后,结合实例分析了构件化测土配方施肥辅助决策系统在大范围推广应用、节约开发成本、缩短开发周期、实现软件重用等方面具有的优势。

  Abstract:Soil testing and formulated fertilization decisionmaking support platform was established by using componentoriented technology. The component system, as a highlight of this platform, was discussed in detail. At the platform analysis cycle,the workflow of soil testing and formulated fertilization was divided into different business units, and as the mapping result of business units, corresponding business components were developed, methods of constructing componentsbased and ondemand soil testing and formulated fertilization decisionmaking support system were also provided. Finally, advantages of componentsbased soil testing and formulated fertilization decisionmaking support system, such as lower cost and shorter system development cycles, easier deployment in different areas, etc., were discussed by a practical example.
