What effect does the LED lamp have on plants?
The LED semiconductor bulb is used as the best light source for plant growth.Proportionally colored lights can make strawberries and tomatoes sweeter and more nutritious. Exposure to Holly seedlings by light is the imitation of plant photosynthesis in the open air. Photosynthesis refers to the process in which green plants convert energy from carbon dioxide and water into organic matter stored in energy by the use of light energy. Sunlight is made up of different colors of light. Different colors of light can produce different effects on the growth of plants.LED light source, also known as semiconductor light source, this light source wavelength is relatively narrow, can control the color of light. Using it to plant plants alone can improve plant varieties.The experiment shows that the holly seedlings in purple light grow the highest, but the leaves are small, the roots are shallow, and they look like malnutrition. Partial yellow light seedlings are not only short, leaves look lifeless. In red and blue, the growth of holly is best, not only strong, but also very well-developed roots. The red light bulb and the blue light bulb of this LED light source are arranged according to the proportion of 9:1.The results showed that the red and blue light of 9:1 was most beneficial to the growth of plants. After this light source, the strawberries and tomatoes were full, the content of sugar and vitamin C increased obviously, and no hollow phenomenon appeared. For 12-16 hours a day, strawberries and tomatoes growing under this light would be better than normal greenhouse fruit.
1. The effects of different wavelengths of light on plant photosynthesis are different. The light needed for plant photosynthesis is at about 400-700nm. 400-500nm (blue) light and 610-720nm (red) contribute most to photosynthesis.2, blue (470nm) and red (630nm) LED, just to provide the necessary light for plants, therefore, LED plant lights, the ideal choice is to use the two color combinations. In the visual effect, the combination of red and blue lights appear pink.3. Blue light promotes the growth of green leaves; red light helps to bear fruit and prolong flowering.4, LED plant lights red, blue, LED ratio is generally between 4:1--9:1 is appropriate, usually optional 4-7:1.5, plant light for plant growth, leaf height distance of 0.5 meters, every 12-16 hours of irradiation can completely replace the sun continuously.
LED plant growth lights can also be used in winter to add light to plants.Lamp holder: international standard E27/E26 structure.Voltage: AC AC120V~240V.Size: external diameter: 62mm height: 95mm.LED number: 54 red, with 6 blue or 6 high-power 1W red, with 1 high-power 1W blue.Color: red, blue, pink.Angle of illumination: 60-120 degrees.Scope of application: vegetable greenhouse, agriculture and forestry horticulture.Energy consumption: 3-7W (relative to ordinary light bulbs, can save more than 95% of electricity)Lifespan: 30000-50000 hours.LED plant growth lamp adopts imported high brightness chip, low attenuation, low energy consumption and high efficiency, plant growth promotion effect is obvious, has very low energy consumption long life and other characteristics, is the other ordinary lights can not be compared, widely used in lighting plant cultivation places, can replace the sun light to the indoor flowers, greenhouse vegetables, the garden nursery were to help fill, regulating flowering, survival etc.. The light effect definitely better than high pressure sodium lamp, low pressure sodium lamps, metal halide lamp, PHILPS plants fill light, rare earth plant lights and other traditional plant lights.
