县域水稻精确栽培决策支持系统研究与开发——以姜堰市为例

The Study and Development of the Decision Support System of Rice Precise Cultivation in County Scale:Take Jiangyan City as a Case

运用农业信息技术原理与方法,以姜堰市为例,初步开发出了功能全面、内容丰富、现势性强、图形生产力高的基于VB6.0和MapObjects2.3的县域水稻精确栽培决策支持系统软件。该系统涵盖了基本苗精确定量、精确施氮、精确灌溉、精确测产及气象数据库、智能学习等内容。该系统还具有电子地图浏览导航与地理信息系统空间数据查询功能。经初步试用,系统的功能可用性、功能可靠性、易用性较强,用户满意度较高。

The software of Decision Support System of rice precision cultivation in county scale taking Jiangyan city as a case was developed primarily by means of the principle and method of agriculture information technology. It had complete functions, abundant contents, strong practice and high graph productivity. The system covered many contents such as precision quantity of base seedling, precision N application, precision irrigation, precision yield measuring, meteorological database and brainpower learning and so on. It also had base GIS spatial analysis functions such as an e-map guide, overlay analysis and spatial data query and so on. In practice, its functions was useable, dependability, simplification, the users are very satisfied with it.
