| 摘 要： | 对江苏省无线电研究所生产的TDR型土壤水分监测仪、中电集团27所和河南省气象科学研究所研制的FDR型土壤水分监测仪监测结果同烘干称重结果进行对比分析,结果表明:TDR、FDR都具有快速、方便、不扰动土壤的优点;但TDR测量的精度受限于测量时间t,投入试运行以来未经订正,误差较大;FDR能获得土壤水分的连续曲线,校正简单,订正后测量精度明显提高。

| Abstract: | The TDR soil moisture monitor was produced by Jiangsu Province Radio Scientific Research Institute,and the FDR soil moisture monitor was produced together by Henan Institute of Meteorological Sciences and the 27th Research Institute of China Electronics Technology Group Corporation.The monitoring results that using the TDR and FDR soil moisture monitor compare with the result that using weighing method.The result indicated that TDR and FDR have advantages such as fast,convenient and not disturbing the soil.Because the TDR measurement accuracy is restricted in measurement time t and the TDR doesn't pass through revising since preliminary operation,the error is bigger.The FDR can obtain the continuous curve on soil moisture,the adjustment is simple,and the measurement accuracy greatly is improved after revising. |
