安徽省县域测土配方施肥决策系统开发与应用研究

Development and Application of Decision-making System for Soil Testing and Fertilizer Recommendations at County Level in Anhui Province

随着农业部测土配方施肥项目的开展,安徽省各项目县通过采样化验、布置试验等,获得了大量数据。为了满足项目县充分利用这些数据指导当地农业生产的要求,研究开发了针对县域的测土配方施肥决策系统。该系统以Microsoft.NET Framework为平台进行开发,主要包括两个功能模块:一部分为主界面模块,通过向导式操作,最终生成配方施肥建议卡;另一部分为管理界面模块,可以对土壤养分测试值、有效养分校正系数、肥料利用率等有关数据和参数进行调整。系统采用向导式操作,简单易懂,便于操作,易于推广。

With the project of soil testing and fertilizer recommendations from Ministry of Agriculture,thec ounties obtained mass data through the sampling tests and field experiments in Anhui province.Thed ecision-making system for soil testing and fertilizer recommendations at county level was developed for thesec ounties by making full use of these data to guide local agricultural production.This system was developedb asing on Microsoft.NET Framework as a platform,including two functional modules that one was the maini nterface module,through wizard-style operation to produce fertilizer formula proposed card;and the other wast he management interface module,in which the data and parameters about nutrients content in the soil,thec orrect coefficient of available nutrient,fertilizer utilization rate and so on can be adjusted and updated.Thes ystem has user-friendly wizard-mode operation,which is easy to understand and generalize.
