Embodiment Construction

[0023] The present invention is described in further detail now in conjunction with specific embodiment, a kind of sample collection method of farmland dry soil roughness detection, comprises the following steps:

[0024] (1) Take a dry and soft cloth and cover it on the soil surface so that the cloth fits on the soil surface;

[0025] (2) Spread the viscous agent evenly on the upper surface of the cloth, and the cloth is further attached to the soil surface by the gravity of the viscous agent;

[0026] (3) Dry the cloth evenly coated with viscous agent on the surface, so that the soft cloth becomes hard cloth, and the contour of the hard cloth surface is the roughness contour of the soil surface to be detected.

[0027] Among them: the first step is to attach the cloth to the surface of the soil to be tested, and initially show the roughness profile of the soil; the second step is to apply the viscous agent evenly on the surface of the cloth to further highlight the roughness...

Abstract

The invention discloses a sample collection method for detecting the roughness of dry soil in farmland. On the basis of cooperation of a piece of soft and dry cloth with a gluing agent, the flexible cloth is processed into a piece of hard cloth; and the roughness of the formed hard cloth is consistent with that of to-be-detected soil. Therefore, the surface roughness of the to-be-detected soil canbe simulated and depicted well and thus detection is carried out by another way, so that no soil needs to be transported to a lab for detection; the accuracy of the detection is improved; 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 dry farmland soil roughness detection. 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] At present, for the measurement of soil surface roughness, the soil to be tested is generally transported to the corresponding measurement laboratory for measurement. This method requires more manpower, and the surface roughness It is easy to be affected and changed, which will eventually lead to large errors in measurement results. Contents of the invention [0004] The present invention overcomes t...
