Photosynthetic rate detection device and method, storage medium and electronic equipment

The invention relates to a photosynthetic rate detection device and method, a storage medium and electronic equipment, and relates to the technical field of gas detection.The device comprises a gas pump, a flow meter, a leaf chamber, a gas detection unit, a flow control assembly, a CO2 gas source and a control unit; and the controller is used for determining the CO2 consumption amount corresponding to the detection period according to the gas concentration variation amount corresponding to each detection period and the gas flow rate of the detection period, inputting CO2 into the gas pump according to the CO2 consumption amount corresponding to the previous detection period of the detection period for each detection period, and outputting the CO2 into the gas pump. And determining the photosynthetic rate corresponding to the detection period according to the CO2 consumption corresponding to the previous detection period of each detection period and the CO2 consumption corresponding to the detection period.
