摘要
通过对比TDR(时域反射仪)法与烘干称重法测定土壤含水率,针对TDR在宁夏泾源县的土壤水分测定进行了标定及适用性研究.结果表明,TRIME-T3 TDR不适用于精确的表层土壤含水率的测定;在TDR标定过程中采用分段标定的方法能够取得相关性更好的标定方程.
By comparing measurement of soil moisture with drying weighing method and TDR（Time Domain Reflect meter）,calibrated TDR was applied to measure soil moisture in Jingyuan County, Ningxia. The test result shows that TRIME- T3 TDR is not applicable for precise determination of surface soil moisture and subsection calibration method can obtain better correlation equation.
