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。
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.
