摘要： 针对水稻生产上氮肥过量施用，氮肥当季利用率低等问题，以姜堰市为例，初步开发了基于PDA的县域水稻精确施氮决策支持系统。该系统是根据水稻因土精确施氮决策的要求及PDA的特性，在拓展PDA自身存储能力的基础上，基于Windows Mobile以及Embedded Visual Basic 3.0、ArcGIS 9.2与集成GPS模块而研制开发的一套农业应用软件PDA产品（V1.0）。该系统具有实时定位、按专题地图查询属性数据、因土精确施氮决策与学习辅导等功能。经试用，用户具有较高的满意度。

Abstract: Aiming at the questions such as excess N application, low N utilization rate at the season in the process of rice production, Decision Support System of precise N application in rice in Jiangyan city based on PDA was developed primarily. To meet with Precise N application in soil and PDA characteristics and according to exploiting PDA memory ability, the system was a suit of agricultural application software of PDA production（V1.0）, which was based on Windows Mobile, Embedded Visual Basic 3.0, ArcGIS 9.2 and integrated GPS module. The system integrated many functions such as real-time location, attribute data query based on the thematic map, precise N application decision-making according to the soil, study and tutor and so on, the users were very satisfied with it in practice.
