The pesticide plays an important role in agricultural production, and in agricultural production in China, the used pesticides are various, including 600 types of insecticides, herbicides, bactericides, rodenticides and the like. The use of pesticides is a leap in agricultural production, and in order to prevent insect disease threat and promote crop growth, the pesticides are used more extensively in China, so that the content of pesticide residues in soil is higher, the pesticide residues in animals are easy to accumulate or the pesticide poisoning event is easy to cause, and the health of the public is harmed. Therefore, the detection of pesticide residues in soil becomes an important part of environmental detection.

The detection and analysis of pesticide residues in soil require accurate sampling of the soil, which is to extract a part of samples from the whole raw material or product, and estimate the quality of the whole batch of food by analyzing one or several samples. In chemical quantitative detection, the accuracy of sampling is often an important factor affecting the accuracy of detection.

Because the infiltration of pesticide in soil, in the soil of the different degree of depth, pesticide residue's content also is different, consequently, during the sampling, need sample respectively to the soil of the different degree of depth, and among the prior art, to the sampling of the different degree of depth soil, often need carry out a lot of sampling operation, not only waste time and energy, seriously influence the efficiency of whole detection, and sample easily inaccurate.
