| Abstract: | Time Domain Reflectometry (TDR) is introduced briefly and the principles, characteristics and application techniques of TDR used in the measurement of soil water content are discussed in this paper respectively. Based on two experiments of the application of TDR to the soil water measurement, which are the simulated experiment of soil water movement of drip irrigation in laboratory and the experiment of water permeability of microporous plastic sheet in field, some advantages of TDR applying to water-saving agriculture are discussed. |
