基于GIS的南丰蜜桔配方施肥研究

A Research on Mandarin Orange Fertilizer Recommended on GIS Basis

以南丰蜜桔施肥为例,结合南丰县2005—2007年土壤采样数据,采用ESRI MapObjects组件,在VB 6.0中开发南丰蜜桔配方施肥决策支持系统,实现了桔园施肥配方的实时、动态查询.研究表明,测土配方施肥技术结合GIS具有更好的实用性,能够为南丰蜜桔的科学施肥提供技术支持.

This paper takes mandarin orange as a case study.With the support of soil sampling data in Nanfeng county during 2005～2007,the Fertilizer Recommendations Decision Support System of Mandarin Orange（FRDSSMO） was developed based on ESRI MapObjects component in Visual Basic 6.0.In FRDSSMO,the fertilizer prescription of orange garden can be had real time.The results show that： integrating GIS to the technology of soil testing and fertilizer recommendation has more practicability to support fertilizing of mandarin orange.
