Embodiment 1

[0023] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, an in-situ whole root soil fixation effect tester, its specific structure includes: a displacement detection device, a horizontal translation mechanism, and a direct shear box for planting plant samples; the direct shear box includes an upper half of the box body 11 And lower half box body 12; Horizontal guide rail 13 is provided between upper half box body 11 and lower half box body 12; Described displacement detection device comprises displacement sensor 31; This displacement sensor 31 is used for detecting upper half box body The horizontal displacement of the body 11 relative to the lower half of the box body 12; the horizontal translation mechanism drives the upper half of the box body 11 to move closer to or away from the displacement sensor 31 along the horizontal guide rail 13, and detects that the horizontal translation mechanism acts on the upper half of the box body. The power on the upper box...

Abstract

The invention discloses an in-situ whole root soil reinforcement effect testing instrument. The testing instrument structurally comprises a displacement detection device, a horizontal moving mechanism and a direct shearing box used for planting plant samples. The direct shearing box comprises an upper half box body (11) and a lower half box body (12). A horizontal guide rail (13) is arranged between the upper half box body (11) and the lower half box body (12). The displacement detection device comprises a displacement sensor (31). The displacement sensor (31) is used for detecting horizontal displacement of the upper half box body (11) relative to the lower half box body (12). The horizontal moving mechanism drives the upper half box body (11) to move close to or away from the displacement sensor (31) along the horizontal guide rail (13) and detects force of the horizontal moving mechanism on the upper half box body (11). The soil shear strength enhancing effect of plant root systems on the original growth conditions can be conveniently and accurately tested, and testing of the plant soil reinforcement effect is more precise.

Description

technical field [0001] The invention relates to the field of measurement of plant slope consolidation effect, in particular to an in-situ whole root soil consolidation effect measurement instrument. Background technique [0002] At present, the research on the effect of plant slope consolidation mainly focuses on the mechanical properties of single plant root against pullout. The test method is mainly to dig out the plant root system from the soil and then refill it to measure its soil consolidation effect. However, the actual roots of plants have different growth angles, different diameter distributions, and different root structures, and each type of root system has a different effect on enhancing soil shear strength. The actual bonding between plant roots and soil is not measured accurately. Contents of the invention [0003] In order to solve the technical problem that the existing soil-fixing effect measurement method overestimates the actual bonding between the plan...
