Description

Technical Field

[0001] This invention relates to the field of intelligent crop management technology, and in particular to an intelligent device for high-throughput population crops. Background Technology

[0002] Photosynthesis is one of the most important chemical reactions on Earth. It absorbs light energy, synthesizes energy-rich organic matter from carbon dioxide and water, and releases oxygen. Chlorophyll fluorescence detection technology can comprehensively reflect the photosynthetic state of plants and characterize the living state of plant samples, which is unmatched by other non-destructive testing techniques for plant physiology. Agricultural modernization is also a key aspect of my country's sustainable development strategy, focusing on achieving carbon peaking and carbon neutrality.

[0003] For group crop management, appropriate management methods (such as providing water and fertilizer support) need to be adapted based on on-site data (such as light data).

[0023] The present invention has the following beneficial effects: The chlorophyll fluorescence measurement method used in the present invention is a general modulation measurement fluorescence method. This method uses modulation measurement light with low photon density to irradiate plant leaves, detect the fluorescence excited by them, and uses strong light intensity saturated light pulses to measure the changes in fluorescence and determine the fluorescence parameters of chlorophyll.
