【摘要】 结合广东省实际,从满足测土配方施肥项目成果应用和推广的实际需求出发,利用现有土壤地理信息、肥料数据、作物施肥模型和信息技术,采用Arc GIS Engine组件开发技术和Modbus RTU通信协议,开发了以县为单位的测土配方自动配肥控制系统。应用结果表明,该控制系统能有效地管理测土配方施肥项目各项数据和土壤地理空间数据,并在此基础上实现县域内针对精确地块的作物施肥配方和施肥指导推荐,同时能完成现场配制出满足农民个性化需求的配方肥。更多还原

【Abstract】 Combined with the actual of Guangdong Province, for meeting the actual needs of application and promotion of soil testing and formulated fertilizer project, the automatic control system for soil testing and formulated fertilizer taking county as a unit was developed, using existing soil geographic information data, fertilizer data, crop fertilization model and information technology, by Arc GIS Engine component technology and Modbus RTU communication protocol. Preliminary results showed that the control system can effectively manage the soil data and geospatial data in soil testing and formulated fertilizer project, achieve the crop fertilizer and fertilizer recommendation for precise guidance at the county level, and can complete the fertilizer formula to meet the individual needs of farmers on site.更多还原
