Soil Water Storage Meter

Abstract

The invention relates to a soil water storage measuring instrument, which is vertically inserted into the soil, and comprises: a rod-shaped outer frame body, one side of the outer frame body has a medium groove vertically penetrating the upper and lower ends of the outer frame body, the The medium tank has two parallel and opposite tank walls, and the two tank walls are provided with a plurality of electrode tanks arranged at equal intervals along the vertical direction, wherein one column of electrode slots is embedded with positive electrode plates, and the other row of electrode slots is embedded with negative electrodes. An electrode plate, the positive electrode plate and the negative electrode plate face each other in parallel and form a capacitor space; the electrode plate is also connected with a central processing module. The soil water storage measuring instrument can still work normally when the instrument is completely submerged, and monitors the near-surface soil water storage with a soil layer thickness within 2m.

Description

technical field [0001] The invention relates to a water storage capacity measuring instrument, in particular to a soil water storage capacity measuring instrument which can be used in an over-humid surface environment. Background technique [0002] Soil water is one of the important components of the earth's water body. Soil can store natural precipitation to meet the water demand of crop growth, which is very similar to the water storage function of surface reservoirs. Soil water storage capacity is an important evaluation index of soil water storage capacity and ecosystem environmental status. [0003] In the over-wet surface environment, such as various types of wetlands, temporary flooding areas, and lakes and rivers with significant water level fluctuations, part of the water in the surface environment is stored in the soil, and part of it is stored on the surface, and it is constantly changing. Carry out space-time interactive transformation. The fluctuation monitori...

AI Technical Summary

Problems solved by technology

[0004] Traditional soil water storage measurement equipment generally uses a probe-type sensor structure. The probe-type structure generally sets a probe at a distance of tens of centimeters. The measurement result can only represent the soil moisture content of a single point, and cannot represent dozens of water volume in centimeters of soil layer

[0005] At the same time, due to the influence of water in the over-humid surface environment, etc., when the instrument is completely submerged, the instrument is easily damaged and affects the accuracy of the measurement results.
