摘要:
土壤中的水盐含量及其动态演化与农田生产及生态环境等密切相关。土壤水盐含量受到作物、土壤和栽培技术等多重因素的影响，其动态监测是业界的一大难题。该文结合水盐含量影响土壤介电特性这一特性，通过运用新型频域反射、分频技术，进行高频段土壤水分以及低频段土壤水盐含量的测定，再采用基于土壤质地的水盐标定方法，排除水分对盐分数据的影响，从而实现土壤孔隙水盐含量的同时测定。从2013年至今，将FDR传感器在天津市18个监测点的应用情况进行了分析，证明了该种传感器工作的有效性和准确性。
Abstract:
The contents and dynamic evolution of soil water and salt are closely related to agricultural production and the ecological environment. The dynamic monitoring of soil water and salt is a big challenge in the practice due to multiple impact factors such as the crop, soil and cultivation technique. Based on the results of the present study of soil water and salt content effects on the dielectric properties of the soil by using the model, frequency domain reflection technology, using frequency division technology, the high frequency of soil moisture measurement, frequency of soil water and salt content of the comprehensive measurement, and the soil texture calibration method based on elimination effect of water on salinity data, the simultaneous measurement of soil pore salt and water content can be realized. The analysis of the sensor in the application of the 18 monitoring points in Tianjin City has demonstrated the effectiveness and accuracy of the sensor since 2013.
