Description

Technical Field

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

[0002] The study of 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, an air chamber is generally used for measurement. The air chamber is fixed on the side of the trunk and then connected to the gas measuring equipment to achieve dynamic monitoring of trunk respiration. For example, in the traditional measurement system, a test device and a test method for trunk gas emissions disclosed in patent document CN202310646972.7 require the air chamber to be pasted on the surface of the trunk and then sealed with plasticine; for example, patent Document CN201610635738.4 discloses a static box for measuring the methane transmission rate of mangrove trunks. It is necessary to first fix the air chamber with a cable tie and then seal it with the trunk with a sealing strip and a silicone foam sealing strip. It can be seen that the air chambers in the prior art need to be fixed on the trunk first and then fixed with a sealing material, that is, this type of air chamber can only meet one measurement. Once removed, it needs to be sealed repeatedly for measurement again. The monitoring of trunk respiration is often a continuous process.
