| From the year of 2005, a new roud soil testing and fertilizer action was carried out all over the country. As the development of the work, the questionnaire which were writen on papers were more and more. It is difficult to query and search those dates and the compiled analysis of those work needs a heavy workload. Fertilizers prescription is the core in the technical links of soil testing and fertilizer. But the key of scientific and rational fertilizers prescription is fertilization formula.In this study, according to practical situation of Hu Bei province, by the technology of computer, net, datebase and WEBGIS, we develop the soil testing and fertilizer data management and application system to solve the difficult of manmagement and treatment of attribute data. It will be a practical significance and wide application prospect to obtain scientific and rational fertilizers prescription, which will help to improve the level of fertiliztion and work efficiency, accelebrate the transition of traditional agriculture to modern agriculture, promote the progress of land nutrition management tecnology. The main results were as follows:(1) Eatablish the soil testing and fertilizer data management and application attribute database.Analysis the soil testing and fertilizer technical specification which was established by ministry of agriculture, according to datebase design code, design and establish attribute database scientificly and rationally, which laid a foundation for the construction of soil testing and fertilizer data management and application attribute database.(2) Design and realize soil testing and fertilizer data input and management systemCombined with system attributes datebase, design and realize soil testing and fertilizer data input and management system. The system with the function of input, delete, modify and seek of date, which solve the difficult of manmagement and treatment of attribute date and improve the work efficiency.(3) Eatablish county land resources database of Hu Bei provinceBy the technology of GIS , the maps and dates of soil testing and fertilizer country were collected. County land resources database of Hu Bei province was eatablished. The acurate management of land resources was relaized.(4)Eatablish recommended fertilization WEBGIS systemAfter the study of Hu Bei province country fertilization model, open source WEBGIS palatform MapGuide Open Source was used to establish WEBGIS recommended fertilization system which based on WEBGIS. Fertilizer rate was determined by sentific way, which improve the economic benefit of fertilizer, realize the aim of increase output, benefit and comprehensive agricultural production capacity. |
