Description

technical field

[0001] The invention relates to a soil layer scraping sampler, which belongs to the field of soil sampling equipment in soil science, agronomy, ecology, geography and environmental science. Background technique

[0002] Soil has a very important research status in many disciplines such as soil science, agronomy, ecology, geography and environmental science. It is very important to collect scientific soil samples according to the purpose of the experiment. In order to carry out multi-item determination and obtain detailed soil profile characteristics research results at the same time, it is very meaningful to conduct stratified sampling as accurately as possible and obtain more soil samples at each level during the soil sample collection process.

[0003] At present, soil drilling or destructive excavation are mostly used in the collection of soil layered samples. If soil drills are used for collection, the layering depth can generally be controlled at about ...
