Abstract
Description

[0002] Soil sampling refers to the method of collecting soil samples, including the layout of sampling, tools and sampling techniques. Soil sampling is a basic step in soil testing. Through soil sampling, representative soil samples can be obtained for soil testing and analysis to understand the physical and chemical properties of the soil, heavy metal content and other information.
[0003] During the sampling process, attention should be paid to the representativeness of the samples, the depth and layer of sampling, the selection of sampling tools, the processing and preservation of samples, etc., in order to ensure the accuracy and reliability of the samples. Sampling different soil layers through soil samplers can improve the representativeness of the samples.

However, the soil taken out by this method is easy to spill, so re-sampling is required, which affects the sampling efficiency. In addition, soils from different layers are easy to mix together, which will cause errors in the experimental results. Utility Model Content
