【摘要】 水肥管理是作物生产中最主要的措施。为研究烤烟水肥一体化专家管理系统,采用"正向推理"策略求解问题,利用已有的研究技术成果及有关水肥耦合试验数据拟合的水肥产量函数(数据未列出),在Windows操作平台环境下运用Visual Basic 6.0程序设计语言进行开发。开发出的单机版"烤烟水肥专家决策管理系统"功能模块包括系统使用说明模块、烟草常用种植技术模块、施肥管理决策模块、登录及用户管理模块、耗水量及灌水量决策模块、灌排逐日决策模块、优质烤烟常规品质评价及历史结果查询模块。实例应用本系统进行N、P、K施肥量、耗水量、灌水量等决策,结果精度较高。为进一步烤烟农业专家决策系统的深度开发提供了依据。更多还原

【Abstract】 Watering and fertilizing management is the most important measure for crops. In order to develop a useful decision-making expert system for water and fertilizer management for flue-cured tobacco(FCT) growth,forward-chaining strategy and Visual Basic 6.0 under Windows was adopted with researched results and water-fertilizer yield function fitted by water-fertilizers coupling experiment data of FCT(not listed). The designed system contained system instruction module,common tobacco planting technology inquiry module,fertilization decision-making module,logging and users management module,decision module of water consumption and irrigation quantity,daily decision module for irrigation and drainage,routine quality evaluation of high quality FCT,history result query module. In a case study, it was used for the decision-making of N,P and K fertilizers,irrigation amount and water consumption of FCT in different growing periods, and the results had high precision. This system provides the basis for further development of the expert decision system of flue-cured tobacco agriculture.更多还原
