Problems solved by technology

[0003] Since the roughness of each position on the soil surface is different, when it is necessary to measure the surface roughness of a certain position on the soil surface, it is generally necessary to cut out this part of the soil separately for measurement, which is too complicated and labor-intensive , and the soil is easily deformed during the cutting process, resulting in errors in the measurement results

Embodiment Construction

[0025] Now in conjunction with specific embodiment the present invention is described in further detail, a kind of sample collection method of soil surface local roughness detection, comprises the following steps:

[0026] (1) Spray the viscous agent evenly on the surface of the soil to be sampled to form one or more strips;

[0027] (2) Use a soft and dry strip to stick to the soil surface sprayed with viscous agent, and apply pressure to the surface of the strip to make the strip and the viscous agent completely fit;

[0028] (3) Dry the viscous agent to make the soft strip into a hard strip. At this time, the curve profile formed by the hard strip is the roughness at the position of the soil to be tested.

[0029] Among them: in the first step, after the viscous agent is sprayed, it is not suitable to stand still to avoid the viscous agent from solidifying; in the second step, the strips used can be flexible dry materials such as cloth strips and strings, so that the strips...

Abstract

The invention discloses a sample collecting method for detecting local roughness of a soil surface. On the basis of cooperation of a soft and dry bar-shaped object with a gluing agent, the flexible bar-shaped object is processed into a hard bar-shaped object; and the roughness of the formed hard bar-shaped object is consistent with that of to-be-detected soil. Therefore, the soil surface roughnessof the to-be-detected position can be simulated and depicted well based on combination of the soft and dry bar-shaped object with the gluing agent; the local position of the soil can be sampled; theoperation becomes simple; post-stage detection is carried out conveniently; the high detection precision is ensured; and the labor intensity of the operator is reduced.

Description

technical field [0001] The invention belongs to the technical field of soil roughness sample collection, in particular to a sample collection method for detecting local roughness of the soil surface. Background technique [0002] Soil surface roughness is an important parameter that characterizes soil hydrological characteristics and affects soil properties. In the study of soil moisture retrieval by microwave remote sensing, soil surface roughness is an important factor affecting backscattering. Therefore, it is necessary to accurately measure soil surface roughness Spend. [0003] Since the roughness of each position on the soil surface is different, when it is necessary to measure the surface roughness of a certain position on the soil surface, it is generally necessary to cut out this part of the soil separately for measurement, which is too complicated and labor-intensive , and the soil is easily deformed during the cutting process, resulting in errors in the measureme...
