摘要
土壤水分是土地持续利用、水资源规划与管理、环境化学、节水农业技术研究的基础。介绍了时域反射仪(TDR)及其测定土壤水分的方法及应用,并利用时域反射仪结合土钻法测定土壤容重,与经典的环刀法测定土壤容重进行了比较,结果表明:两种测定结果存在一定的差异,TDR结合土钻法测定土壤容重能连续测定而且稳定性好。
As known to all,soil moisture was foundation of continued use of land,the management and planning of water resources, envlronmental chemistry and saving of agricultural water research. This paper introduced TDR and the method for determination of soil moisture and its application. The soil bulk density was measured by TDR combined with soil sampling. The results were compared with that of classical round knife method. The way of TDR combining soil sampling compared with the classical way of round knife method. The results showed that the measured values were different. The TDR measurement was continuous monitoring, and it was accurate and stable.
