摘　　要：充分利用农业部广泛开展的测土配方施肥丰富的技术成果和基础数据,以土壤养分丰缺指标法和养分平衡法分别构建区域施肥模型和精准施肥模型,基于esupermap for.NET平台进行二次开发,运用嵌入式GIS、移动式GPS定位技术,PDA用户可随地获取土壤养分、施肥技术、缺素图谱等。系统以安徽省金寨县为例,针对茶园与农作物耕地,分别具备精准施肥和区域施肥两种方案,解决施肥技术推广的瓶颈问题,使施肥技术成果被更精准快速的推广应用。The soil determination and prescription fertilisation project, widely carried out by the Ministry of Agriculture, has generated various technical outcomes and fundamental statistics. Our research puts these data into fullplay, based on rich or pool index method of soil nutrition and nutrition balance theory, we structure the models of both sectional and accurate fertilising methods respectively. Secondary development has been also made on the basis of eSupermap for. NET platform, the fitted GIS and mobile GE5 locating technology are applied. In this case,the PDA users is able to acquire the information of soil nutrition, fertilising technology, element deficiency atlas and etc. The system sets Jinzhai County as an example, and has solved the bottle neck problem in precise and fast promotion and application of fertilising technology outcomes by carrying out both sectional and accurate fertilising approaches for tea and crops farras respectively.
