Description

TECHNICAL FIELD

[0001] The application relates to the technical field of farmland soil nitrogen gas sampling devices, in particular to an optimization device facilitating collection of ammonia volatilization of dry land soil. BACKGROUND

[0002] Ammonia volatilization is a main way of nitrogen loss of farmland soil, which reduces the utilization efficiency of nitrogen fertilizer on the one hand, and causes fog, atmospheric dry and wet deposition and greenhouse effect and other focal environmental problems after ammonia volatilization enters the atmosphere on the other hand, so that simple and accurate soil ammonia volatilization monitoring is of great significance for scientific evaluation of farmland nitrogen fertilizer whereabouts, guidance of reasonable fertilization of farmland and reduction of environmental impact caused by ammonia emission.

[0003] The sponge ventilation method has the advantages of good ventilation, convenience and economy and is suitable for soil ammonia volatilization collection of multiple treatments of farmland. However, in the traditional sampling process, the sampling tube is inserted into the soil, and due to uneven pressure, the sampling tube is not flat after being inserted into the soil or the depth of the sampling tube inserted into the soil is changed artificially in the later period, so that the distance between the sponge and the soil is changed, and part of the sponge may be contaminated by the soil; in the process of placing the sponge in the sampling tube, the phosphoglycerol in the sponge is easily leached out due to the complete cutting of the sponge and the collection tube, and the pollutants on the wall of the collection tube are also easily contaminated on the sponge; when the sponge is pressed into the sampling tube, the sponge is also easily contaminated by the lower layer of soil due to the uneven position of the sponge, and the leaching solution is contaminated in the later leaching of ammonia in the sponge, which affects the determination result. In addition, the sponge soaked with phosphoglycerol solution is generally placed in a self-sealing bag for storage and then taken to the field for use, and in this process, the phosphoglycerol solution is easily leached out at a certain point of the sponge or the solution is unevenly distributed in the sponge, which affects the accuracy of sample collection.

[0004] Therefore, it is urgent to provide an optimization device facilitating collection of ammonia volatilization of dry land soil, which can quickly and conveniently complete sampling, ensure the accuracy of sampling, and reduce the operation difficulty and human error. CONTENT OF THE INVENTION
