(2) In the illumination stage, chlorophyll converts water and carbon dioxide into organic substances through photosynthesis, while green light inhibits the activity of chloroplasts, so that photosynthesis is reduced.
(3) In the spectrum stage, the spectrum components play a main role in the development and growth of plants. Specific:
the influence of ultraviolet light and ultraviolet rays on plants is as follows: promoting the main light energy of plant to form pigment, and directly affecting the absorption of plant to phosphorus, aluminum and other elements and the formation of vitamin D, the accumulation of dry matter and the formation of horny layer;
influence of blue light on plants: can move chloroplasts and promote photosynthesis;
influence of green light and yellow light on plants: inhibiting chloroplast activity and reducing photosynthesis;
effect of orange-red light on plants: increasing and enhancing photosynthesis of plants, and facilitating plant growth;
influence of far infrared light on plants: mainly used as a plant growth signal lamp for regulating physiological activities such as shade avoidance, flowering and the like of plants.
(4) In the illumination stage, the illumination intensity is a key factor influencing the plant growth, and the spectral content in the light reduces the effect on the plant growth.
Meanwhile, plants absorb different spectrums, the most absorption is orange-red light, the next is blue-violet light and ultraviolet light with the wavelength of 300-500nm, and the absorption is less for green-yellow light with the wavelength of 500-600 nm.
From the above, green light and green-yellow light are less absorbed by the branches and leaves of green plants, and the activity of chloroplasts is inhibited, so that photosynthesis is lowered. Therefore, the light reflected by the green branches and leaves is mainly green light and yellow-green light, and the plant irradiation device can achieve that the yellow-green light and the green light are not irradiated or less irradiated on the green branches and leaves by projecting the complementary color image of the original color image onto the plant.
In an application scenario, the plant irradiation device mainly works in the illumination stage, spectrum stage and illumination stage of plants.
In the illumination stage, after the plant germinates and grows the first few green leaves, the stage begins, and the plant irradiation device starts an infrared lamp and an ultraviolet lamp and projects complementary color images onto the plant through a projector. Accelerating the growth of the branches and leaves of plants.
In the spectrum stage, the plant irradiation device starts an infrared lamp and an ultraviolet lamp, and a complementary color image is projected onto a plant through a projector. Strengthen photosynthesis of plants and promote growth of branches and leaves.
In the illumination stage, the plant irradiation device turns on the infrared lamp and the ultraviolet lamp, the complementary color processing unit 3 performs complementary color processing based on chromaticity after obtaining an original color image output by the video camera, the complementary color image is projected on a plant through the projection unit 2, and branches, leaves, flowers and fruits obtain complementary color light which is complementary with the colors of the branches, leaves, flowers and fruits into white light, so that the growth of the branches, leaves, the rapid flowering phase and fruit ripening can be accelerated, and the plant growth period is greatly shortened.
In the scene of applying the plant irradiation device to tomato planting, the tomato fruits are green in the initial stage, and the fruits gradually change to orange and finally change to red after the volume of the green fruits is increased to a certain degree. The plant irradiation device can accurately project the color light complementary with the color light of the fruit to the fruit, and the projection area of the complementary color light can change along with the change of the size of the fruit, so that the outline surface of the fruit in the projection direction is completely irradiated by the complementary color light. Specifically, in the early stage of the fruit, red light is projected on the fruit, the fruit grows rapidly, when the color of the fruit changes to orange, blue-green light is projected on the fruit, so that the fruit changes to red rapidly through the orange period, and when the color of the fruit changes to red, green light is projected on the fruit, so that the fruit is ripe rapidly.
