Knowledge of LED plant lamp for flower and vegetable growth

Popularization of LED plant lamp knowledge:
1. The effect of different wavelengths of light on plant photosynthesis is different. The wavelength of light needed by plant photosynthesis is about 400-700nm. 400-500nm (blue) light and 610-720nm (red) light contributed most to photosynthesis.
2. Blue (470 nm) and red (630 nm) LEDs can just provide the light needed by plants. Therefore, the ideal choice for LED plant lamps is to use these two color combinations. In terms of visual effect, the red and blue combination of plant lights is pink.
3. Blue light can promote the growth of green leaves; red light can help to blossom, bear fruit and prolong the flowering period.
4. The red and blue LED ratio of LED plant lamp is generally between 4:1 and 9:1, and 4-7:1 is usually optional
5. When the plant lamp is used to supplement light for plants, the height from the leaves is generally about 0.5 meters, and the continuous exposure of 12-16 hours a day can completely replace the sunlight.
Because plants need sunlight to grow more luxuriantly. The effect of light on plant growth is to promote chlorophyll to absorb nutrients such as carbon dioxide and water and synthesize carbohydrates. However, modern science can make plants grow better in places where there is no sun. People have mastered the internal principle of plants’ need for the sun, that is, the photosynthesis of leaves. The whole process of photosynthesis can be completed only by the excitation of external photons. The sunlight is a transient energy supply process excited by photons. Artificial light sources can also make plants complete the photosynthetic process. Modern horticulture or plant factories combine light supplement technology or complete artificial light technology. Scientists have found that the blue and red light regions are close to the efficiency curve of plant photosynthesis and are the best light sources for plant growth.
LED semiconductor bulb is used to configure the most suitable light source for LED plant lamp
Color lights set in proportion can make strawberries and tomatoes sweeter and more nutritious. To irradiate the seedlings with light is to imitate the photosynthesis of plants outdoors. Photosynthesis refers to the process that green plants use light energy to convert carbon dioxide and water into organic substances that store energy and release oxygen through chloroplasts. Sunlight is composed of different colors of light, which can produce different effects on plant growth.
LED light source also known as semiconductor light source, this light source wavelength is relatively narrow, can control the color of light. If you use it to irradiate the plant alone, you can improve the plant variety.
Through the experiment, the seedlings of Ilex latifolia under purple light grew the highest, but the leaves were very small, the roots were shallow, and they looked like malnutrition. Under the yellow light, the seedlings are not only short, but the leaves look lifeless. The winter Holly grown under the mixed red and blue light is the best, not only strong, but also very developed roots. The red bulb and blue bulb of this led light source are configured according to the ratio of 9:1.
