Technical Field

[0001] The utility model relates to soil detection equipment, in particular to a soil sampling detection device. Background Art

[0002] Soil environmental monitoring is a technical means to dynamically analyze and measure the degree and development trend of soil pollution. Soil environmental monitoring aims to prevent and control the hazards of soil pollution and is an important measure to understand the status of soil environmental quality. Soil environmental testing includes investigations on the current status of soil environmental quality, investigations on regional soil environmental background values, investigations on soil pollution accidents and dynamic observations of polluted soils, and is carried out through steps such as preparation, site placement, sampling, sample preparation, analysis and testing, and evaluation.
