湖北省莲藕施肥推荐专家咨询系统的设计与实现

摘要

湖北省莲藕施肥推荐专家咨询系统是基于莲藕营养特性与施肥技术研究成果,主要用来指导莲藕生产过程中合理施肥,以提高莲藕产量和改善莲藕品质,同时提高肥料的利用效率,避免盲目施肥对农田水环境造成污染.该系统基于Web服务,运用JSP、Servlet、JavaBean技术,采用B/S结构和MVC (Model-View-Controller)开发模式,能够给出藕田土壤肥力的客观评价,并在此基础上提供科学的施肥建议,将结果采用Excel模板输出,用户可方便地保存和使用.%Rhizome lotus fertilization recommendation system, developed from the research achievements of nutrition characteristics and fertilization technology on rhizome lotus, was used to instruct farmers to apply fertilizers properly in rhizome lotus production in order to increase yield,improve rhizome lotus quality and fertilizer use efficiency, and also avoid the pollution caused by excessive applying fertilizers. Web service, JSP, Servlet and JavaBean technology, MVC (Model-View-Controller)development model were used and a B/S structure was formed in the system. Based on the system, objective evaluations of soil fertility and the corresponding fertilization recommendations could be given by exporting in Excel files. It was very convenient to save and utilization.
