[0002] Soil respiration is an important indicator of life activities in the soil, and accurate measurement of its release is the key to evaluating biological processes in ecosystems. By measuring soil respiration and its related parameters, the response of roots and soil microorganisms to soil environment and climate change can be estimated. 2 Flux is affected by many factors, and accurate determination of soil carbon flux is of great significance to the study of carbon flux in terrestrial ecosystems. Currently, researchers mostly use the Li-8100A soil carbon flux automatic measurement system to measure soil respiration. This type of instrument can not only perform a single measurement, but also set the time and monitoring frequency, conduct monitoring for up to several months, and simultaneously measure data from different locations to complete the accurate determination of soil carbon flux at different spatial scales.
[0003] In many application scenarios, it is necessary to use a standard breathing ring that meets the specifications of the Li-8100A instrument. The standard breathing ring mainly limits the inner diameter of the breathing ring. However, in practical applications, there are many situations where breathing rings with standard inner diameters cannot be installed, and therefore the soil carbon flux cannot be measured in a standardized manner, which seriously limits related research and makes it impossible to accurately obtain soil carbon flux data. Therefore, there is a need for a device that can measure soil carbon flux for non-standard breathing rings to improve the breadth and scientificity of terrestrial ecosystem carbon flux research.
