Description

TECHNICAL FIELD

[0001] The present application relates to the field of sampling technology, in particular to a sampling tool for saline-alkali soil information. BACKGROUND

[0002] Salt-alkali soil sampling is a challenging but crucial work. By following scientific sampling methods and precautions, the nature and condition of salt-alkali soil can be accurately understood, thereby providing scientific basis for soil improvement, agricultural production and ecological protection. At present, when sampling salt-alkali soil, a soil drill is usually used for sampling. When using the soil drill, both hands need to hold it and vertically insert the soil drill into the soil, then rotate the soil drill for sampling. After pulling out the soil drill, a scraper is needed to remove external contaminants. The central section is cut and put into a sample bag. If the soil drill shakes left and right during sampling, horizontal shear force will be generated between the soil drill and the soil, which will squeeze the soil particles to rearrange them, even crush the aggregate structure, resulting in impact on sampling quality and data reliability.
