DEVELOPMENT AND APPLICATION OF A PORTABLE PRECISION FARMING SYSTEM
In order to realize the portable and digital crop production management. Based on the theory of precision agriculture and the precision crop management model, a Pocket PC-based portable precision farming system (PPFS) was developed by integrating Pocket PC, embedded-GIS, SQL Server CE and GPS, using the thought of system engineering and software component technology. The system realized the functions such as map handling, information management, cultural plans design, fertilizer and water management, suitable growth indices design, real-time regulations based on the crop growth status, and system help. In 2007-2008, the demonstration and application of PPFS were carried out in Jiangsu, Zhejiang and Henan provinces. The results in field experiments indicated that, system could design suitable crop precision management schemes based on field factual status, the average rice yield with precision management plans was 10435.3 kg·m-2, with increasing rate being 12.83％; the average wheat yield with precision management plans was 8124.6 kg·m-2, with increasing rate being 9.02％, and the mount of nitrogen fertilizer was reduced. The present work provided a new service platform and application pattern for precision farming management.
