摘　　要：文章针对温室灌溉自动化程度低、灌溉模式落后、植株吸水性差等问题,以单片机为核心模块,利用传感器实时采集土壤含水量,设计精准灌溉自动控制系统,并围绕系统组成、试验结果、分析内容,探究了温室精细灌溉自动控制系统及其应用情况。试验表明,当温室灌溉控制系统响应满足设计值时,土壤的平均水分占比约为70.5%,满足温室作物生长环境需求,具有良好的实用性和控制精度。Aiming at the problems of low degree of irrigation automation,backward irrigation mode and poor water absorption of plants in greenhouse,the automatic control system of precision irrigation is designed by using single chip microcomputer as the core module to collect soil water content in real time with sensors.The experiment shows that when the response of greenhouse irrigation control system meets the design value,the average water proportion of soil is about 70.5%,which meets the environmental demand of greenhouse crop growth,and has good practicability and control accuracy.
