Problems solved by technology

The sand collector can collect wind erosion at different heights, but it cannot determine the amount of wind erosion per unit area in a specific area. In addition, the sand collector uses the swing of the wind vane to drive the bearing to rotate to realize the sand collection mouth facing the wind, and it is placed in the field for a long time. , it is easy to reduce the sensitivity of the bearing rotation and affect the observation data

Embodiment Construction

[0026] As shown in the accompanying drawings, the embodiment of the present invention's soil wind erosion measuring disc has a structure of:

[0027] Such as figure 1 As shown in the figure, the middle plate, the inner ring, and the outer ring of the wind erosion measurement plate are set together to fix the cloth laid flat on the bottom of the middle plate.

[0028] Such as image 3 As shown, the diameter of the middle plate is 25-30 cm, the wall thickness is 0.1-0.2 cm, the depth is 5 ± 0.5 cm, there are permeable holes at the bottom, the hole diameter is 0.3-0.5 cm, and the material is stainless steel.

[0029] Such as Figure 4 As shown, the outer ring is made of elastic stainless steel, with a wall thickness of 0.1-0.2 cm and the same diameter as the middle plate. It is an unclosed ring with a gap of 1-2 cm, and the width of the outer ring is 2±0.5 cm.

[0030] Such as Figure 5 As shown, the inner ring is also made of elastic stainless steel, with a wall thickness of...

Abstract

The invention relates to a soil wind erosion measuring disc. The soil wind erosion measuring plate is composed of a central plate, an inner ring, an outer ring, and a piece of cloth laid on the bottom of the central plate; the central plate is a cylindrical plate, and a Evenly distributed permeable holes; the inner ring and the outer ring are elastic non-closed rings, and gaps are respectively opened on the inner ring and the outer ring; the cloth is squeezed and embedded between the inner ring and the middle plate, and the bottom of the plate cling. The method of using the soil wind erosion measuring plate to measure the amount of wind erosion in the field is: (1) select a flat measuring site; (2) measure the soil water content of the measuring site; (3) take the corresponding volume of soil according to the volume of the wind erosion measuring plate, and then Measure the mechanical composition of the soil; (4) After the outdoor measurement period is over, take out the soil in the pan to measure the water content and measure the mechanical composition of the soil; (5) Determine the soil mechanical composition according to the following formula: soil wind erosion = (M1‑X1)‑(M2‑X2), Wind erosion amount of soil with the same particle size = (M1‑X1)×Q1‑(M2‑X2)×Q2. The invention has the advantages of reasonable structure, small measurement error, and can be placed in the field for a long time.

Description

technical field [0001] The invention relates to equipment used for environmental ecological research, in particular to a soil wind erosion measurement disk and a measurement method for quantitative observation of field soil wind erosion. Background technique [0002] The amount of wind erosion is an important indicator for judging soil loss and desertification, and it is also one of the important bases for formulating desertification prevention and control plans and determining wind erosion prevention measures for soil classification and classification. At present, the commonly used instruments and equipment for field wind erosion observation of soil mainly include wind erosion circles, inserting drills, and sand collectors. Researchers use these instruments and devices to complete the field monitoring of soil wind erosion, but different devices have their own advantages and disadvantages. Although the wind erosion circle limits the wind erosion area, because the gauze in t...
