土壤养分是苹果树生长和结果的基础,实现县域苹果园地块土壤养分信息的可视化管理和应用,可为苹果产业发展提供合理的施肥依据。该文以陕西黄陵县苹果园为例,将苹果园土壤肥力等级与施肥模型结合,借助ArcGIS Server技术,在ASP.NET框架下设计开发了县域苹果园土壤养分信息系统。该系统采用三层架构设计,具有地图基本操作、养分信息查询与定位、专题图浏览、施肥推荐等功能。实践表明,该系统将苹果园土壤养分信息以网络的形式发布,便于数据的直观显示和信息共享,为科学高效地进行苹果园农业现代化管理与果业发展提供了技术支持,为后续应用系统的扩展奠定了基础。
Soil nutrient is the basis of apple tree growth and fruiting, and the visual management and application of soil nutrient information in apple orchard plots in county can provide reasonable fertilization basis for apple industry development. Taking apple orchards in Huangling County of Shaanxi Province as an example, this paper combines the soil fertility level of apple orchard and fertilization model with ArcGIS Server technology to design and develop the soil nutrient information system of apple orchards in counties under the framework of ASP.NET. The system uses three-tier architecture design, with the basic operation of the map, nutrient information query and positioning, thematic map browsing, fertilization recommendations and other functions. Practice shows that this system will release information of apple orchard soil nutrient in the form of network, which facilitates the visual display and information sharing of the data, provides technical support for the scientific and efficient management of apple orchard agriculture modernization and fruit industry, Expansion laid the foundation.
