Analyze the application of LED plant light to photosynthesis

Plants need sunlight to grow more lush. The effect of light on plant growth is to promote plant chlorophyll to absorb carbon dioxide and water and other nutrients, and to synthesize carbohydrates. But modern science can make plants grow better in places where there is no sun. People have mastered the inherent principle of plants' need for the sun, which is the photosynthesis of leaves. When photosynthesis of leaves requires external photon excitation, the whole photosynthetic process can be completed. The sun's rays are the energy-passing process of photon excitation. The artificial creation of light sources also allows plants to complete the photosynthetic process, and modern horticulture or plant factories combine light-filling technology or complete artificial light technology. Scientists have found that the blue and red regions are very close to the efficiency curve of plant photosynthesis and are the best source of plant growth.

LED plant light knowledge:

1. The light of different wavelengths has different effects on plant photosynthesis. The light required for photosynthesis of plants has a wavelength of about 400-700 nm. Light from 400-500 nm (blue) and 610-720 nm (red) contribute the most to photosynthesis.

2. Blue (470nm) and red (630nm) LEDs just provide the light needed by the plant. Therefore, LED plant lights are ideal for using these two color combinations. In terms of visual effects, the red and blue combination of plant lights is pink.

3. Blue light promotes green leaf growth; red light contributes to flowering and prolongs flowering.

4. The ratio of red and blue LEDs of LED plant lights is generally between 4:1 and 9:1, usually 4-7:1.

5. When the plant light is used to fill the plant, the height of the blade is generally about 0.5 meters, and the continuous irradiation for 12-16 hours per day can completely replace the sunlight.

Use LED semiconductor bulbs to configure the most suitable source for plant growth

Proportional color lights make strawberries and tomatoes sweeter and more nutritious. Illuminating the holly seedlings with light is to imitate the photosynthesis of plants outdoors. Photosynthesis refers to the process by which green plants use light energy to convert carbon dioxide and water into organic matter that stores energy and release oxygen through the chloroplast. Sunlight is composed of different colors of light, and different colors of light can have different effects on plant growth.

LED light source is also called semiconductor light source. This kind of light source has a relatively narrow wavelength and can control the color of light. By using it alone to illuminate the plant, the plant variety can be improved.

The holly seedlings tested under purple light have the highest growth, but the leaves are small, the roots are shallow, and they are malnourished. The seedlings under the yellow light are not only short, but the leaves look lifeless. The holly growing under the mixed light of red and blue is the best, not only strong, but also very developed. The red and blue bulbs of this LED source are configured in a 9:1 ratio.

The results show that 9:1 red and blue light is most beneficial to plant growth. After this light source, the fruits of strawberries and tomatoes are full, the content of sugar and vitamin C is obviously increased, and there is no hollow phenomenon. Continuously irradiating for 12-16 hours a day, strawberries and tomatoes grown under such a light source will be better than ordinary greenhouse fruits.

LED plant growth lights can also be used to supplement light sources in plants during winter rainy weather.
