摘要

现有的根系分区交替灌溉装置仍停留在手动控制阶段,需要通过机械或连杆的操作实现作物局部根区的交替灌溉,费时费力,响应速度慢,并且需要借助其他实验观测资料判断作物根区的实际含水情况,确定是否需要灌水以及何时需要交替灌水,严重影响控制精度。为此本文设计了一种交替灌溉智能控制系统,分析了系统工作原理,进行了硬件设计并开展试验。试验结果表明该系统具有较快的响应性和较强的稳定性,土壤水分利用效率提高了9%,通过现场或远程调整作物类型,可以满足玉米、棉花、蔬菜等作物的交替灌溉要求。
Intelligent Control System of Crop Partial root-zone Alternative Irrigation includes Signal acquisition module, it is used for real-time collecting soil moisture information lying in different root-zone; Control module uses the lateral root zone moisture difference alternate threshold, maximum of soil moisture, minimum of soil moisture and measured soil moisture in real-time information to control the motor of Irrigation system. This system is suitable for controlling the partial root-zone alternative irrigation automatically, the corn, cotton, potatoes and other field furrow irrigation of crops and fruit trees and greenhouse vegetable crops.
