Background

Soil sampling refers to a method for collecting soil samples, and comprises sampling arrangement and sampling technology. The sampling of the soil sample in the cross section is performed after the cross section observation is completed. Soil samples for studying soil chemistry only require that a sufficient number (e.g., 1-2 kg) of samples can be taken at a characteristic depth without maintaining the original shape.

There are many types of soil samplers. And (3) collecting a surface soil sample of the farm land or the wasteland, wherein a small iron shovel can be used. The cutting ring can be used for researching general physical properties of soil, such as soil volume weight, porosity, water retention property and the like.

The traditional artificial soil sample collecting device is simple in structure, inconvenient to operate and high in labor intensity, when the device is lifted, the internal soil falls off, and soil samples are not easy to take down from the device and easily influence the soil detection result; meanwhile, after the soil falls off, the depth of the soil cannot be determined, which may cause the collected soil sample to be unrepresentative, thereby affecting the reliability of the detection result.
