Soil microorganism determination sampler

Abstract

The invention relates to the field of soil collection, in particular to a soil microbiological measurement sampler which comprises a base and a plurality of sampling barrels, detachable loading barrels are mounted at two ends of the top of the base, a supporting rod is mounted between the two loading barrels on one side of the top of the base, and a first hydraulic column is connected to the top of the supporting rod; a second motor is installed at the top of the first hydraulic column, three horizontally-arranged second hydraulic columns are evenly connected to the outer wall of the output end of the top of the second motor, and sampling barrels capable of moving up and down are rotationally installed at the ends, away from the second motor, of the second hydraulic columns. A plurality of sampling frames from top to bottom can be used for collecting and sampling soil from top to bottom, so that the content of microorganisms at different depths in the soil can be clearly known. The sampling frame and a soil sample detection result taken out during sampling can assist each other, so that the detection accuracy can be improved.

Description

technical field [0001] The invention relates to the field of soil collection, in particular to a soil microorganism determination sampler. Background technique [0002] Soil microorganisms are a general term for all microscopic organisms in the soil that are invisible or unclear to the naked eye. In the strict sense, it should include bacteria, archaea, fungi, viruses, protozoa and microscopic algae. Its types and quantities vary with the soil-forming environment and soil depth. They carry out processes such as oxidation, nitrification, ammoniation, nitrogen fixation, and sulfidation in the soil, and promote the decomposition of soil organic matter and the transformation of nutrients. In order to determine the content of microorganisms in the soil, the soil is often sampled with a sampler and then measured. [0003] When soil sampling, a cylindrical sampler or a drill bit is often used to punch and sample the soil. When encountering hard black soil or soil containing sand...

AI Technical Summary

Problems solved by technology

When encountering hard black soil or soil containing sand and gravel, it is difficult to enter the interior of the soil with a cylindrical sampler, and it is difficult for the soil to stay inside the sampler, resulting in less soil being taken out

The use of drills to drill holes and subsequently sample them in the boreholes increases the sampling procedure while preventing accurate measurements of soil microbes at different depths

In a small area, multiple samples are taken to improve accuracy. The efficiency of the above two methods is low, and it is difficult to sample in the same environment that contains multiple regional environments.
