Description

Technical Field

[0001] The present invention relates to the technical field of greenhouse gas measurement, and particularly to a trunk respiration measurement system. Background Art

[0002] The research on greenhouse gas emissions from trees is an important part of ecosystem research. The main greenhouse gases emitted by trees are carbon dioxide and methane. In the prior art, gas chambers are generally used for measurement. By fixing the gas chamber on the side of the tree trunk and then connecting the gas chamber to the gas detection device, the dynamic monitoring of trunk respiration can be realized. In traditional measurement systems, such as a test device and test method for trunk gas emissions disclosed in patent document CN202310646972.7, it is necessary to paste the gas chamber on the tree trunk surface and then use putty for sealing; for another example, in a static chamber for measuring the methane transmission rate of mangrove tree trunks disclosed in patent document CN201610635738.4, it is necessary to first fix the gas chamber with cable ties and then seal it with the tree trunk through sealing strips and silicone foam sealing strips. It can be seen that the gas chambers in the prior art all need to be fixed on the tree trunk first and then fixed with sealing materials. That is to say, such gas chambers can only meet one measurement. Once removed, if another measurement is required, repeated sealing is needed.
