[0001] The utility model relates to the technical field of dryland greenhouse gas collection, and specifically relates to a retractable and portable dryland greenhouse gas collection box. Background Technique

[0002] As one of the important biogeochemical processes in terrestrial ecosystems, soil respiration is of great significance in maintaining soil nutrients and reducing greenhouse gas emissions. Carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), etc., as the main sources of greenhouse gases, the quantitative study of soil greenhouse gas emissions has become a key research direction in many disciplines such as environmental science, ecology, and soil science. At present, most gas sampling boxes are large in volume and inconvenient to carry and use.

[0015] Preferably, an air extraction hose is also vertically inserted into the top plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The TPU material cover is made of TPU material coated with a heat-insulating, heat-preserving, and wear-resistant coating. The manual telescopic rod acts as a frame, supporting the top plate, the TPU material cover, and the first ring. The TPU material cover is made of heat-insulating material. When the top plate is pressed down, the manual telescopic rod can be shortened, allowing the top plate to move downwards by a certain distance. The TPU material cover can be folded, making the entire collection box smaller and easier to carry.

[0018] The second ring can be installed on the lower surface of the first ring using the locking fasteners. Then, the four posts can be inserted into the soil to fix the entire collection box on the upper surface of the soil. Greenhouse gases generated in the soil can rise through the center of the first ring and the center of the second ring into the interior of the TPU material cover.

[0019] The fan helps the gas mix evenly inside the TPU material enclosure, and the temperature recorder can accurately record the temperature inside the chamber during sampling. After the gas collection is completed, the manual telescopic rod can be shortened and the top plate can be moved downwards to reduce the overall volume of the collection chamber, making it easy to move and carry.
