基于模型的冬小麦-夏玉米两熟数字化种植设计系统构建

构建基于模型的定量化和数字化种植设计系统。以农业系统学理论和模拟模型为基础,运用知识工程和信息技术原理,总结并提炼黄淮海粮食生产区冬小麦-夏玉米一年两熟制种植模式关键技术,形成了冬小麦和夏玉米生长模拟模型、水分与养分动态平衡模型以及生产管理技术设计动态知识模型,构建了冬小麦-夏玉米两熟数字化种植设计系统。该系统采用面向对象的程序设计方法,在.NET平台上运用C#语言进行开发。该系统具有7大功能模块:文件管理模块、参数管理模块、生长模拟模块、实时管理模块、方案设计模块、专家咨询模块和系统帮助模块。该系统界面友好,易于使用,具有较强的机理性,同时兼顾应用性需求,基本实现了作物生产力与效益品质的相互平衡。

Construction of model-based cropping design system for wheat-maize rotation

This experiment aims to build a digital and quantitative model-based system for cropping design.The wheat and maize growth simulation model,water and nutrient dynamic balance model,and dynamic knowledge model for production management,based on knowledge engineering and information technology,were firstly developed by summarizing and extracting the key technique for wheat-maize cropping system in Huang-Huai-Hai region.The cropping design system for wheat and maize was secondly built by coupling the growth simulation model with the knowledge model.According to object-oriented programming method,this system was programmed in the.NET framework with C sharp language.This system consisted of seven function modules,including file management module,parameter management module,growth simulation module,real time management module,plan design module,expert consultation module,and help module.It was user-friendly and operating-conveniently,and has good mechanism and better application.The balance between crop production and cost performance has been primarily realized.
