摘　　要：FDR系统在土壤水分监测中应用广泛。对一种新型管式智能一体化FDR系统进行介绍,并将系统应用于土壤水分监测。在内蒙古河套灌区的应用实践表明,FDR能够监测土壤含水量的连续变化情况,获得土壤中客观发生的水分数据,实时计算作物根系所在土壤当前有效储水量和蓄水潜力,为科学灌溉做出决策。The FDR system is widely used in the monitoring of soil moisture, this paper introduces a new type of FDR system, applies the system to soil moisture monitoring. Application practices in He Tao irrigation area of Inner Mongolia show that FDR is able to monitor the continuous change of soil moisture content, and obtain moisture data in soil Real- time computation of the soil＇s current effective storage and storage potential, making decisions for scientific irrigation.

关 键 词：FDR 土壤含水量 校正 应用
