Abstract


Since 2005, China began to implement soil testing and fertilizer operations, all over the county, city and district units batches have moved into the project and the completion of the mandate of the project, each completed unit will generate a lot of results in the implementation process of the project The data includes fertilization zoning map, cultivated land fertility, and a variety of nutrients map. However, these outcome data and more data files or in the form of paper maps exchanges and save, is not conducive to the management and sharing. Soil testing fertilization project the outcome of the promotion more than carry out technical training and technical consulting, to farmers payment formula fertilization card and other form, but these methods exists with information on a single, timeliness, and cost disadvantages of restricting the outcome of the fertilization project for soil testing The effectiveness of the play. At the same time, the spatial database technology, modern geographic information technology, global positioning systems, embedded technology, mobile networking technology has made considerable development, and gave birth to a mobile GIS technology together. Technological advances for the above-mentioned problems in the implementation process of the study and solve soil testing and fertilizer projects laid the foundation. The subject from ESRI's ArcGIS Mobile technology foundation to meet the actual demand for soil testing and fertilizer projects starting developed based mobile GIS the fertilization promotion system. The system initially solved the problem in the project implementation process, the practical requirements for basic functionality, performance, ease of use, security aspects. This study completed the following tasks: (1) to investigate the organization of the data in the form of soil testing and fertilizer results; established technical solutions based on Oracle ArcSDE spatial database of soil testing and fertilizer outcome data, outcomes data on soil testing and fertilizer effectively manage, easy to update and share. (2) for the low performance of the system terminal capacity and the screen is small, requiring constant glare impact in the field conditions, bandwidth and low, map colors, symbols, and the proportion of careful design. (3) ArcGIS Server spatial data server publishing spatial data services, and discusses the management of space data services through ArcCatalog and ArcGIS Manager on mobile. (4) SQL Mobile is based on the of fertilization model parameters and knowledge base, developed its modify and query function modules, users through their terminal software to query or modify. (5) ArcGIS Mobile to develop a fertilization promote mobile terminal software development environment Visual Sudito 2005. The software functionality, performance, ease of use, security has basically reached the practical requirements.
