The embodiment of the invention provides a soil ice content detection method and device. The method comprises the following steps: acquiring detection information of soil, acquiring the first ice content of the soil according to the detection information and a preset soil ice content model, wherein the input quantity of soil ice content model is the detection information, and the output quantity is the first ice content. The device comprises a power source, a circuit control board, a platinum electric resistance probe and at least two stainless steel probes, wherein the platinum electric resistance probe and each stainless steel probe are used for detecting the detection information of the soil, each stainless steel and the platinum electric resistance probe are all connected with the circuit control board; the circuit control board is used for controlling each stainless steel probe and the platinum electric resistance probe to acquire the detection information, and acquiring the first ice content of the soil according to the detection information and the preset soil ice content model. By use of the method provided by the embodiment of the invention, the accuracy of the soil ice content measurement is improved.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of soil detection, and in particular to a method and device for detecting ice content in soil. Background technique [0002] In seasonally frozen soil regions, the soil freeze-thaw cycle process has an important impact on agricultural production and the ecological climate environment. For example, in spring, farmers will infer the best time for farming according to the thawing of farmland soil. Therefore, people pay more and more attention to the research on the change law of the freeze-thaw cycle of seasonal frozen soil in farmland. The freeze-thaw cycle process of soil is essentially a process of mutual conversion between free water and ice in the soil, so it is particularly important to be able to detect the ice content in farmland soil in real time. [0003] In the early research on permafrost, the soil freezer was widely used as a simple measurement tool. Its structure is comp...
