摘要

Collected the soil test data of Wannian county and droped it on the map to verify the accuracy of the spatial loca-tion and made sure that the data was reliable , and processed the second soil survey data of Wannian county and extract the soil types and other related information, then checked on the spot.On this basis and for the demands of integrated information service system of soil testing and formulated fertilization, built soil type database, soil nutrient database, terrain slope database, rice nu-trient information database, utilization rate of fertilizer information database, and established the entity relationship ( E-R) model, and divided fertilization units by comprehensive related information and production capacity , in order to build the basic da-tabase based on the fertilization units, get the fertilizer application rate and fertilization scheme according to those related fertiliza-tion models to recommend rice fertilization formula of each fertilizer unit in Wannian county .%将万年县耕地土壤采土检测的数据进行上图并核实空间位置的准确性以及数据的可靠性,并且对万年县第二次土壤普查相关数据进行处理,提取耕地土壤类型等相关信息,并在实地予以核实校对。在此基础上,按照测土配方施肥综合信息服务系统功能的要求,构建了土壤类型数据、土壤养分数据、地形坡度数据、水稻需肥信息、肥料利用率信息库等数据库,并建立了实体-关系模型( E-R),按综合相关信息以及生产能力划分万年县水稻施肥单元,构建了基于施肥单元的基础数据库,并依据测土配方施肥综合信息服务系统相关施肥模型计算不同施肥单元的肥料施用量与施用方案,推荐了万年县水稻施肥各个施肥单元的配方。
