Embodiment Construction
[0043] see figure 1 and figure 2 Generally speaking, the soil carbon dioxide flux in-situ measuring device of the present invention comprises:
[0044] The bottom ring 3 is pre-fixed on the ground where the carbon dioxide flux of the soil surface layer is to be measured, so as to determine the measured area;
[0045] When the soil carbon dioxide concentration is to be measured, the opening measuring container 6 installed on the bottom ring 3 is sealed;
[0046] Initial carbon dioxide concentration value (X 1 ) after sealing the lid 7 of the opening measuring container 6 opening; and
[0047] The carbon dioxide analyzer 1 connected to the open measuring container 6 .
[0048] Wherein, the carbon dioxide analyzer 1 uses infrared rays to measure the carbon dioxide concentration value of the soil.
[0049] Wherein, before the opening measuring container 6 is sealed and installed on the bottom ring 3, the carbon dioxide analyzer 1 is connected with the gas inlet pipe 2 and the ...
