Device for sampling wetland soil

Abstract

The invention discloses a device for sampling wetland soil and relates to the technical field of soil sampling. The device comprises a sampler and a sampling tube, wherein the sampler comprises a sampler top cover, a sampler barrel and a plugging cover; a ventilation cavity, a plugging cover mounting chamber and a sampler inner cavity which are communicated in sequence are arranged in the samplerbarrel from top to bottom; through holes communicated with the outside are formed in the side walls of the ventilation cavity; the plugging cover is mounted in the plugging cover mounting chamber; theventilation cavity and the sampler inner cavity can be communicated or closed through vertical movement of the plugging cover; the sampler top cover is fixed at the upper end of the sampler barrel, and the sampling tube and the lower end of the sampler barrel are detachably connected. The device for sampling the wetland soil is easy to carry, soil samples are easy to take out, the original stateof the soil can be kept better, working efficiency is improved, and soil samples of different types of wetland in different positions can be collected and stored.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a device for sampling wetland soil. Background technique [0002] As a special type of ecosystem in the transition between land and water, wetlands, together with forests and oceans, are known as the three major ecosystems in the world. Although the wetland area only accounts for 4% to 6% of the global area, the carbon storage in the wetland ecosystem accounts for 12% to 24% of the global terrestrial carbon storage. The high productivity level and special reducing environment in the wetland ecosystem, Make the wetland present the function of carbon sink in the process of carbon storage. With the in-depth study of the driving mechanism of global change, wetlands, as an important carbon source or carbon sink, have been paid more and more attention, and have become one of the research hotspots and key contents in wetland science.

Problems solved by technology

However, the above-mentioned technologies and patents focus on the process of taking out the soil, but they cannot provide good help in the subsequent sample processing and storage process.

At the same time, these solutions cannot efficiently collect and store soil samples for different types of wetlands in different locations through a set of equipment in the complicated actual work.
