Problems solved by technology

[0006] In view of the problems existing in the deep soil sampling and detection technology in the prior art that soil samples are easy to contaminate each other, sampling reliability is poor, detection accuracy is not high, results after contamination are biased, and predictions cannot be effectively given, the present invention provides a deep soil sampling And the sample detection method, the method of pre-drilling and inserting layered samplers to avoid pollution can effectively distinguish samples from different soil layers without contamination of the upper and lower layers, and the detection results are more accurate. It is suitable for all-item sampling analysis

Abstract

The invention relates to a deep soil sampling and sample separation detection method, which belongs to the technical field of soil detection, and comprises the following steps: pre-drilling, sampling at multiple points on the side wall, directly carrying out sample separation packaging according to the sampling points after sampling, and finally carrying out treatment and detection to obtain a more accurate sample point result. The sampler is designed according to a sampling method and comprises the sampling rod and the sampling grooves, the sampling rod is provided with the scale marks, and the multiple sampling grooves are longitudinally arranged along the sampling rod, so that sampling is more accurate, interlayer cross contamination is prevented, one-time multi-point sampling can be conveniently achieved, and the sampler has good practical value and is particularly suitable for whole-term accurate analysis.

Description

technical field [0001] The invention belongs to the technical field of soil detection, and in particular relates to a deep soil sampling and sampling detection method. Background technique [0002] In recent years, with the environmental pollution, overuse and application of chemical fertilizers brought about by economic development, soil degradation has accelerated, and desertification, acidification, barrenness, and scarcity have become increasingly serious, which will pose a threat to production and life. Therefore, it is necessary to test this type of soil and make reasonable improvement or utilization planning. Soil testing not only needs to test the surface soil, but also needs to test the deep soil, so as to facilitate targeted monitoring or restoration management of the soil. [0003] Soil testing refers to determining the environmental quality and its change trend through the determination of representative values ​​of factors affecting soil environmental quality. ...
