Embodiment Construction
[0031] Such as figure 1 As shown, the present embodiment includes: a guide rail 5 and a frame 4 that moves horizontally along the guide rail 5, wherein the guide rail 5 is two slide rails parallel to each other, and the bottom end of the frame 4 is provided with pulleys that match the slide rails;
[0032] A camera 2 arranged on the top of the frame 4 for collecting the reflected light information of the plant to be measured;
[0033] A light source 1 composed of 16 LED lamps 9 is installed on the frame 4 for projecting detection light to the plant to be tested.
[0034] Such as figure 2 As shown, the outgoing light path of the LED lamp 9 is provided with a light guide cylinder 7 and a lens 8 arranged in sequence for adjusting the outgoing light into a uniform rectangular beam of light. In order to help the LED lamp 9 to cool down better, a A radiator 6 is provided.
[0035] Wherein, the light guide tube 7 is a rectangular tube surrounded by four reflecting mirrors, so tha...

The invention discloses a plant chlorophyll fluorescence detection device comprising a guide rail and a rack moving along the guide rail; a camera arranged at the top part of the rack and used for collecting reflected light information of a plant to be detected; a plurality of LED (Light Emitting Diode) lamps installed on the rack and used for projecting detection light to the plant to be detected, wherein a light path assembly used for adjusting emergent light to a rectangular streamer is arranged on the emergent light path of each LED lamp, and the corresponding rectangular streamers of the LED lamps are collected to the same region. The plurality of LED lamps project facula to the same region in an overlapping manner to reinforce the illumination intensity, lenses are arranged in the LED lamps to guarantee uniform illumination, so that the plant chlorophyll fluorescence detection device disclosed by the invention can be used for performing plant chlorophyll fluorescence detection on a large green area, and moreover, the plant chlorophyll fluorescence detection device is simple in structure and convenient to install and move.
Description
technical field [0001] The invention relates to a detection device, in particular to a plant chlorophyll fluorescence detection method. Background technique [0002] Photosynthesis is one of the most important chemical reactions on the earth. It uses sunlight to split water to release most of the oxygen needed on the earth, and at the same time fixes carbon dioxide in the atmosphere to provide glucose for metabolism. In the light reaction process of photosynthesis, the absorbed light energy is transferred. In the process of converting into electrical energy, part of the light energy loss is released in the form of longer-wavelength fluorescence. Under natural conditions, chlorophyll fluorescence has a very close relationship with photosynthesis. Many changes in the photosynthesis process can be reflected by chlorophyll fluorescence. Due to its fast, reliable, sensitive, and non-destructive characteristics, it has developed rapidly. . [0003] The commonly used measurement...
