Agricultural soil pollution degree detection device

Abstract

The invention discloses an agricultural soil pollution degree detection device, and belongs to the technical field of soil detection. The agricultural soil pollution degree detection device comprisesa cylinder body; three supporting legs are hinged to the bottom of the cylinder body at equal intervals in a surrounding mode; a storage type handle is movably installed at the top of the cylinder body; a soil liquid phase detector and a soil gas phase detector are fixedly installed on the left side and the right side of the cylinder body respectively; opening and closing plates are arranged belowthe soil liquid phase detector and the soil gas phase detector respectively, and the two opening and closing plates are hinged to the left side and the right side of the cylinder body respectively and are designed to penetrate through the inner wall of the cylinder body. According to the agricultural soil pollution degree detection device, a sampling mechanism is adopted, so that sampling work ofsoil at different depths can be completed in the process of inserting and pulling out of a soil layer at a time, the problem that detection accuracy is affected due to mutual doping of soil at different depths can be effectively avoided, and the sampling mechanism can effectively smash and store solidified soil blocks in the sampling action process.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to an agricultural soil pollution degree detection device. Background technique [0002] my country is a big country in the production and use of pesticides. The long-term excessive and simple application of chemical fertilizers has deteriorated the physical properties of the soil, polluted the land and changed its original use. Excessive accumulation of nitrate and phosphate in the soil will flow into rivers, lakes and other waters with water, which will cause eutrophication of water body. As a result, it has a serious impact on the ecological environment, and even threatens the normal life and health of residents. Soil detection methods generally include gas chromatography, ASF soil detection method, high performance liquid chromatography and X-ray fluorescence spectrometry. The above methods all need to be tested by soil sampling. In order to solve the disadvantages of lo...

Problems solved by technology

However, the degree of soil pollution is different at different depths underground. Therefore, when sampling soil at different depths, it is necessary to insert and pull out the sampling device multiple times to complete the sampling of soil at different depths. During the process, the contact part between the sampling device and the soil needs to be cleaned after each sampling, so as to avoid the situation that the soil at different depths is mixed with each other and affect the accuracy of the test. Although this sampling method is more efficient than laboratory testing , but there are still defects that affect the detection accuracy and efficiency
