摘　　要：为提高我国农业的科技含量和现代化水平,研究设计了精准农业变量施肥GIS系统,该系统在GPS的定位下,可实现控制大豆变量施肥播种机进行变量施肥播种作业。该软件由VisualBasic6.0语言、地理信息系统MapObjects控件和Microsoft公司串行通信MSComm控件进行编程,通过机载计算机对变量施肥机构进行控制。大豆大面积试验表明,可显著提高单位面积产量。To improve the application of science and technology agriculture of China, the GIS of Variable Rate Fertilization for Precision Agriculture was designed. With GPS technology, this system could be used to control the Variable Rate Fertilizing and Sowing. The software was programmed with Visual Basic 6.0, Map Object of GIS and MSComm Control of Microsoft. It could control the Variable Rate Fertilization machine by computer on the tractor. The large-scale area test of soybean showed that the yield of unit area was improved significantly.
