摘要
土壤水分的测量直接关系到作物的灌溉,进而影响到作物的产量,是一项长期且艰巨的任务。总结了目前市场上3种主流的基于介电原理的土壤水分传感器,阐述了它们的测量原理、标定方法、影响因素以及性能情况,分析了使用过程中可能出现的一些问题,并对其未来的发展方向进行了展望,旨在为农技、水利部门在选用该类型的土壤水分传感器产品和测量土壤水分的过程中提供一定的参考和借鉴。
Soil moisture measurement relating to the crop irrigation directly, which affects the yield of crops, was a long-term and arduous task. Three kinds of the major soil moisture sensors based on the theory of dielectric at present were summarized in this paper. Their measuring principle, calibration method, influencing factor and performance were expounded. The problems in the process of using those sensors were analyzed and their development trends were given in order to provide some reference for the agricultural technology department and water conservancy department in the process of selecting those types of soil moisture sensor products or measuring the soil moisture.
