Description

Technical field

[0001] The present invention relates to the technical field of plant monitoring equipment, and more particularly to a plant transpiration amount measuring device and a method thereof.Background technique

[0002] Transpiration is the process of disseminating from a water vapor state to the air from a vapor surface (mainly leaf) surface (mainly the leaves). The evaporation process of plant transpiration and physics is different. Transpiration is not only affected by the external environment, but also by the regulation and control of the plant itself, it is a complex physiological process, which has a certain difficulty in determination. Currently, the most Commonly used measurement means to use plant transpiration measuring instruments, plant transpiration measuring instruments have a variety of, such as Li-6400 photosynthetic assay system, CB-1101 photosynthetic transpiration assay system, CAF tree transpiration stream measuring system, weighing Steamer, etc., can be said ...
