Problems solved by technology

The traditional soil drill sampling is used for soil research. Each sampling depth is relatively large, and multi-point sampling is required to obtain mixed soil samples. The measured soil salinity data is quite different from the actual value; the soil sample is taken first and then stratified. Whether the corresponding soil layer soil samples are collected during soil sampling will have a great impact on the layered research, and the measured soil salinity data cannot truly reflect the corresponding soil layer data

[0035] This embodiment provides a saline-alkali soil layered sampler A10-20, such as figure 1 , figure 2 and Figure 6 As shown, the saline-alkali soil stratified sampler consists of a rectangular knife, a soil retaining scale plate and a rectangular knife handle. The moment knife is made up of upper knife 1, lower knife 2, inner knife 3 and side knife 4; The mouth is wide, double-sided cutting; the side knife 4 is rectangular, the cutting edge is wide, single-sided cutting, and the opposite side of the cutting edge has a groove to form a tooth platform 5, which is convenient for occlusion with the handle of the rectangular knife; two side knives 4. The upper part is welded with the upper knife 1, the other side is welded with the lower knife 2, and the inner knife 3 is welded equidistantly between the two sides of the knife, the cutting edges are in the same direction, and the cutting edge faces outward; the soil retaining ruler plate 6 is A plate with a special scale. Th...

[0039] The working process of this embodiment is as follows:

[0040] The working process of this embodiment is almost the same as that of the first embodiment, with slight changes in the details. Select the sampling point of the saline-alkali land to be studied, and dig the soil profile to be studied with a shovel. If there are salt crusts on the ground surface, Sampling and analyzing the salt crusts on the surface separately, pressing the handle of the moment knife and the moment knife figure 2 Assemble in the same way and turn it over 180°. At the soil profile where the salt crust is peeled off, the lower knife 2 can just be tangent to the ground surface. Push the assembled saline-alkali soil layered sampler into the soil profile, and hold the moment horizontally with one hand. Knife handle, use the experimental hammer to hit the force pad 11 in one hand to assist in sampling, stop hitting the force pad 11 when the moment knife cuts into the soil horizontally, and put the ...

Abstract

The invention discloses a saline land soil layered sampling device. The saline land soil layered sampling device is composed of a rectangular knife, a soil blocking ruler plate, and a rectangular knife handle. The saline land soil layered sampling device is simple in structure, is convenient to use, is accurate in sampling, and is convenient to carry. The saline land soil layered sampling device is capable of realizing saline land soil layered sampling, the collected soil samples are capable of reflecting real soil layer situations; single time sampling is carried out, saline land soil layeredinterval and sampling amount can be determined by the distances among internal knives in the rectangular knife, article control of saline land soil research precision and labor intensity can be realized, and convenience is provided for research.

Description

technical field [0001] The invention relates to the technical field of soil sampling equipment, in particular to a saline-alkali soil layered sampler for soil layered sampling when soil properties are studied in saline-alkali land. Background technique [0002] Soil sampling is the basic work of soil research, and soil salinity is an important indicator of soil research. However, due to the large vertical variation of salinity in saline-alkali land and the lack of effective soil samplers for saline-alkali land, the research on soil salinity in saline-alkali land stratified It is rare to hear, especially the centimeter-level layered processing is very rare. The traditional soil drill sampling is used for soil research. Each sampling depth is relatively large, and multi-point sampling is required to obtain mixed soil samples. The measured soil salinity data is quite different from the actual value; the soil sample is taken first and then stratified. Soil research is carried...
