摘　　要：针对现行在线式土壤含水量测量方法的不足,依据新型TDT型土壤含水量传感器,设计土壤含水率实时测量系统,分析系统测量结果,得出传感器的敏感部位位于上部的结论,给出传感器埋置的建议。该系统具有结构简单,操作便捷,不受含盐量影响,便于实现土壤含水量网络化测量的特点。Aiming at the disadvantages of the methods of the present on-line measuring soil moisture content, the soil moisture content real-time measurement system was designed based on a new type of TDT soil moisture content sensor. The system measurement results showed that the sensor sensitive part was located in the upper portion, and the sensor embedded suggestion was given. The system had simple structure, convenient operation, not affected by salinity effect, easy to realize the characteristics of soil moisture content network measurement.
