Soil microorganism sample collection tool

Abstract

The invention provides a soil microorganism sample collection tool, and belongs to the field of biological technologies. The soil microorganism sample collection tool comprises a basic piece and a tool bit, wherein a first connection piece is arranged on the basic piece; a second connection piece is arranged on the tool bit; the basic piece and the tool bit are detachably connected with each other through the first connection piece and the second connection piece; the tool bit comprises a connection block and a tool body; the connection block is semispherically annular; the second connection piece is arranged on the outer arc surface of the connection block; the tool body is cylindrical; one end of the tool body is connected with the two free ends of the connection block, and a blade is arranged at the other end of the tool body; a through hole is formed in the side wall of the tool body; a group of symmetric air holes are formed between the tool body and the connection block. According to the collection tool, the original mode of artificial soil excavation sampling is changed, so that the disturbance effect of an iron shovel and the like on a soil microorganism sample is avoided, manmade errors are reduced, the completeness of the soil microorganism sample is guaranteed, and the precision of test sample collection is improved; different drill bits are used on different soil lands, so that the outdoor working efficiency is improved, and the labor and the time are saved.

Description

Technical field [0001] The invention relates to the field of biotechnology, in particular to a soil microbial sample collection tool. Background technique [0002] In the process of microbial cultivation or research, or when analyzing the composition of the soil, it is necessary to extract the soil in nature and conduct corresponding analysis and research. [0003] The traditional extraction method is to use a shovel or a shovel. The defects of this tool and method are obvious: the tools are large and bulky and inconvenient to carry; the use is laborious, resulting in lower work efficiency; the extracted soil structure is irregular and not easy to carry. Easy to preserve and other defects. The existence of these defects restricts the progress of science and technology. Summary of the invention [0004] The present invention provides a soil microbial sample collection tool, which aims to improve the above-mentioned problems. [0005] The present invention is realized as follows: [0...
