The canopy photosynthesis measurement system consists of li-8100 closed-circuit soil carbon flux automatic measurement system (li-cor, USA) and assimilation box designed and manufactured by Beijing ligotai Technology Co., Ltd. li-8100 is an instrument produced by li-cor, USA for soil carbon flux measurement, and the concentration of CO2 and H2O is measured by infrared gas analyzer. The length, width and height of the assimilation box are all 50cm. The assimilation box is controlled by li-8100. After setting the measuring parameters, the instrument can run automatically.
