Fixing and layering partition device for collecting in-situ soil in field

Abstract

The invention discloses a fixing and layering partition device for collecting in-situ soil in a field, which comprises two first partition plates, two second partition plates and a plurality of transverse knives, each first partition plate is perpendicular to each second partition plate, the two first partition plates and the two second partition plates form a square structure, the transverse knife is perpendicular to the first partition plate and the second partition plate, and the first partition plate, the second partition plate and the transverse knife are inserted into one another to forma cube, so that stratified sampling is facilitated, the sampling range, sampling sites, sampling depth and sampling quantity are controlled, and the field sampling accuracy is ensured; the structureis simple, dismounting and combination are flexible, application is wide, and field operation is simple.

Description

technical field [0001] The invention relates to the field of soil sampling equipment, in particular to a fixed and layered partition device for collecting in-situ soil in the field. Background technique [0002] As an important part of the earth's surface system, soil is closely related to agronomy, geographical science, ecology, and environmental science; first of all, soil is the basis for the growth of green plants, and soil cultivation, cultivation, and fertilizer science in agronomy are all based on soil Soil research is an important part of these disciplines. Secondly, from the perspective of environmental science, soil is not only a resource, but also an important component of the human living environment. In addition to being fertile and producing green plants, soil also plays an important role in the living environment and ecological security. Soil research and these disciplines Or the comprehensive research of domain research is also the trend of soil research inn...

Problems solved by technology

The destructive sampling method refers to collecting layer by layer by digging the profile. This method is easy to cause the entire profile to collapse, and the sampling depth is difficult to control, especially when collecting soil samples within 10cm, the error is very large, and it is difficult to grasp the sample collection range and sample size. When collecting soil samples with a soil auger, mixing of soil samples from different layers can be avoided, but the length of the auger is limited, generally about 20cm, and the amount of each collection is small. In addition, if the soil with less water or loose soil Environment (such as sandy soil), the soil drill sample is easy to fall, difficult to operate, etc.; the above methods have the problems of being greatly affected by the soil environment, large collection errors, and difficult to accurately control
