Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a soil multi-point mixed sample sampling tool. Background Art

[0002] Soil is the environmental basis for the growth of crops. The quality of soil determines the yield and quality of crops. Therefore, soil testing is an important part of environmental testing. In the process of soil testing, soil sampling needs to be carried out through a soil sampler. In recent years, some developed countries in Europe and the United States have proposed a decision unit-multi-point incremental sampling based on modern sampling theory. The DUMIS (Deep Intensive Sampling) method collects representative soil samples through multi-point incremental sampling (the number of increments is about 30-100), large sample mass (total mass is about 2-3kg) and suitable sampling tools, and selects 10% of the decision-making units to collect three replicate samples to evaluate the data quality of the entire process of field sampling, indoor sample preparation and laboratory analysis to ensure the representativeness of the samples, the reproducibility of the data and the reliability of the decision-making conclusions (that is, the sampling plot is divided into 30-100 blocks on average, and an equal amount of soil samples are collected in each block, and finally the soils collected from 30-100 points are mixed into one soil sample). At present, developed countries in Europe and the United States have used the incremental sampling method for contaminated site cleanup, soil sampling of hazardous waste sites, soil and sediment site risk assessment and remediation, etc., and have issued a series of guidelines and procedures based on the multi-point incremental sampling method.

[0003] Compared with the current sampling methods, the DUMIS method has strong sample representativeness. For specific spatial variability sampling areas, when the number of sampling points is sufficient, it can fully reflect the average concentration of target pollutants in the sampling area. The obtained data has good reproducibility and reliable decision-making. However, this method also has certain limitations. The DUMIS method has many sampling points. The existing T-shaped sampler needs to sample and take samples one by one, which takes more time. In addition, due to the large number of sampling points, sampling personnel need to carry sampling tools to different sampling points. Most of the existing sampling tools do not have mobile structures and are inconvenient to carry. Utility Model Content
