Schematic (A) (AC an air compressor, CC a CO2 cylinder, SV a solenoid valve, AO the analog output, MBT a mixed buffer tank, MFM a mass flow meter, P: a pump, CH a chamber, I.R.an infrared gas analyzer of the reference CO2, Is an infrared gas analyzer of the sample CO2) and images (B) of the semi-open chamber system for the gas exchange rate measurement of the whole crop canopy: The supplied air passed through a desiccant and soda lime. The desiccant was connected to a three-way valve, and a flow rate regulator could adjust the relative humidity of the air before passing the desiccant. CC was used to create the desired CO2 concentration in the CH. MFC controlled the flow rate of CO2-free air from AC and pure CO2 from CC. MBT was used for agitation of CO2-free air and pure CO2 air by air flow rate. MFM was used to check and control the airflow rate entering the chambers
