摘要
随着现代农业的发展,将灌溉与施肥有效结合,实现精准及自动化控制是现代农业的一个发展趋势。依据作物生长过程中对水肥的动态需求,确定了精准灌溉施肥自动控制系统的控制要求及相关性能指标,通过系统硬件选型、人机界面软件开发以及系统的综合调试,开发了灌溉施肥自动控制系统,实现了上位机软件对灌溉和施肥的自动控制与运行。系统具有手动和自动两种控制模式,具有响应速度快、可靠性高、数据自动记录保存、操作简便等优点。试验运行结果表明:该自动控制系统设计方案合理,系统运行可靠,能够满足设施作物精准灌溉施肥的要求。
With the development of modern agriculture,the effective combination of irrigation and fertilization to realize precision and automation control is a development trend of modern agriculture.According to the dynamic demand of water and Fertilizer in crop growth process,the control requirements of automatic control system for precision irrigation and fertilization and related performance indicators are determined.Through an integrated test system hardware selection,the user interface software and the automatic control system are developed to realize the automatic control and operation software for irrigation and fertilization.The system poses two types of manual and automatic control mode and has the advantages of quick response speed,high reliability,automatic data recording merits preservation,simple operation.Experiment results show that the automatic control system design is reasonable and reliable,and can meet the requirements of precision irrigation and fertilization for facilities crop.
