[0002] Soil carbon storage refers to the total amount of organic carbon in the soil body with a certain area and depth, and it is also the main carbon source of greenhouse gases. Soil carbon storage not only includes the carbon in the surface soil, but also the carbon in the deep soil. Its total amount far exceeds the sum of the carbon in the atmosphere and plants. As one of the main carbon storage systems, the conservation and restoration of soil are crucial for achieving sustainable agriculture and mitigating climate change. The carbon storage in grassland soil has a great impact on the growth state of plants. When the existing equipment detects the carbon storage in grassland soil, the operation of collecting soil samples is relatively cumbersome, which affects the accuracy of soil carbon storage detection.

[0003] When the existing equipment samples grassland soil, the sampling structure moves downward with more effort, which is not convenient for the equipment to collect soil samples at different depths. Moreover, the operation of taking out samples by the existing equipment is relatively cumbersome, and it is easy to spill and cause waste, which affects the accuracy and practicability of the equipment for detecting soil carbon storage. Therefore, the technical personnel in this field provide a device for measuring grassland soil carbon storage to solve the problems raised in the above background technique.
