| 摘 要： | 提供了用TDR土壤水分测试仪在测试土壤含水率的同时可测到土壤含盐总量的方法。以黄河上游宁夏惠农县典型的黄河淤积平原的主要质地土壤为基础。利用德国产TRIME-T3管式TDR土壤水分测量系统在测试田间土壤含水率时表示出的VOL和LEVEL值．经过与电导法测定的土壤含盐总量的拟合，得出它们与土壤含盐总量的函数关系。通过统计原理对该方程的检验．表明了方程的显著性和可用性。

| Abstract: | The method of using soil moisture meter TDR in the simultaneous measurements of soil water content and soil salinity is provided. On the basis of the main soil texture of Yellow River sediment plain of Huinong County, Ningxia, at the upper reach of Yellow River, TRIME T3 made in Germany, a tube typed soil moisture measurement system of TDR, is used in the measurement of soil water content. Through comparison between the value of VOL and LEVEL of the measurement with those of measured by electric conductivity method, the relationship function between soil water contents and salinity is derived. The function is verified by statistics theory, and proved to be significant and practical. |
