Abstract

The invention discloses a measurement method and measurement equipment for the water content of layered soil. The measurement method comprises the following steps: S1, obtaining measurement parameters; S2, starting measuring equipment; S3, when the second soil layer is in a saturated state, receiving a first voltage signal value V1 fed back by the surface soil layer; S4, when the second soil layeris in an unsaturated state, receiving a second voltage signal value V2 fed back by the surface soil layer; S5, calculating the average water content W1 of the surface soil layer by using the first voltage signal value V1 and the second voltage signal value V2; S6, receiving a third voltage signal value V3 fed back by the second soil layer; S7, calculating the water content W' 2 of the second soillayer by utilizing the third voltage signal value V3; S8, calculating the average water content W2 of the second soil layer by utilizing the average water content W1 of the surface soil layer and thewater content W' 2 of the second soil layer, and S9, repeating the steps S6 to S8 until the measurement is completed, so that the rapid measurement of the water content of the multi-layer soil is realized, the measurement strength is reduced, and the measurement precision is improved.

Description

technical field [0001] The invention relates to the technical field of soil measurement, in particular to a method for measuring the moisture content of divided soil. The invention also relates to a measuring device. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] Soil water content generally refers to the absolute water content of the soil, that is, how many grams of water is contained in 100g of dried soil, also known as the soil moisture content. The measurement of soil water content can grasp the water demand of crops, which has very important guiding significance for agricultural production. . [0004] In the prior art, the drying and weighing method is usually used to measure the water content of the soil. During the measurement, the staff will weigh the collected soil, then dry the collected soil, and then weigh the dried soil. Weight, the water content of t...
