example 1

[0042] The distance from the root irrigation hole 4 to the center of the trunk 1 is 1m. If the ring electrode system has four ring electrode arrangements 2, the distance from the ring electrode arrangement 2Ⅰ to the center of the trunk 1 is 0.5m, and the distance from the ring electrode arrangement 2II to the trunk 1 1.5m from the center of the ring electrode arrangement 2Ⅲ, 2.0m from the center of the trunk 1, and 2.5m from the center of the trunk 1 from the ring electrode arrangement 2Ⅳ; if the four radial electrode arrangements 3(a , b, c, and d) all have 16 electrodes, the first electrode is 0.5m away from the center of the trunk 1 and the distance between adjacent electrodes is 0.5m. Take the center of the tree root as the origin (0, 0, 0), take the north direction as the positive X direction, take the east direction as the positive Y direction, and take the ground upward as the positive Z direction. The coordinates of all electrodes are as follows Table 1; Table 2 The da...

Abstract

The invention provides a device and method for monitoring tree root infiltrating irrigation through three-dimensional resistivity, comprising a plurality of concentric annular electrode arrays, a plurality of radial electrode arrays are arranged in the circumferential direction of the annular electrode arrays, and the annular electrode arrays and the radial electrode arrays are connected with a parallel electrical method collector through a multi-core cable. The parallel electrical method collector is connected with an electrical method control and processing platform through wireless transmission equipment. According to the device and method for monitoring tree root infiltrating irrigation through the three-dimensional resistivity, the root irrigation effect can be improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy irrigation, in particular to a device and method for monitoring root seepage irrigation by using three-dimensional resistivity. Background technique [0002] With the increasing number of extreme weather phenomena, urban gardens, ancient trees in the countryside, and ornamental trees, shade trees, and street trees in rare jungles rely on their own roots to absorb water from the surrounding soil, and it is difficult to effectively guarantee the water requirements for healthy growth. Therefore, reasonable irrigation is used. It is very important to maintain a good soil ecological environment. At present, the main irrigation methods are sprinkler irrigation, flood irrigation and infiltration irrigation, etc. Sprinkler irrigation avoids direct impact and erosion on the soil, basically does not produce deep seepage and surface runoff, and effectively saves water resources, but equipment price...
