The advantages of LED plant lights for urban vegetable planting
The development of science and technology and the progress of the times have not only improved people's living standards, but also kept people away from nature. The scale of cities is increasing, and the development of rural areas is like urbanization. People are trapped in steel and concrete cages, and they go to and from get off work repeatedly all day long. The boring life makes people think of the past rural life, fresh, natural and comfortable.
The advantages of LED plant lights for urban vegetable planting
LED plant light makes everything possible. It has rich wavelength types, which coincides with the spectral range of plant photosynthesis and light morphology; it has a narrow half-width of the spectral wave width, and can be combined as needed to obtain pure monochromatic light and composite spectrum; it It can concentrate light of specific wavelength to irradiate crops evenly. LED plant lights can transform urban people into gardeners, who can not only enjoy the fun of planting, but also plant pure natural green vegetables.
LED plant lights can ignore the existence of day and night, you can ignore the changes in spring, summer, autumn and winter, whether it is windy, raining, or snowing, in those days without sunlight, as long as you have LED plant lights, plants can Healthy and happy growth. It has become a thing of the past that everything grows by the sun. LED plant lights can completely replace the sun.
LED plant light is a kind of plant light. It uses the principle that plants need sunlight to provide a light environment for plants to grow and develop. Due to its small size, light weight, long life span, and adjustable light intensity, LED has become one of the important light sources for plant light environment regulation, and has obvious advantages in energy saving and promotion of plant growth.
Analyze the characteristics and functions of LED plant lights
After continuous research, people have found that different wavelengths of light have different effects on plant photosynthesis. Plant photosynthesis requires light, and the wavelength is about 400-700nm. 400-500nm (blue) light and 610-720nm (red) contribute a lot to photosynthesis. LED plant lights are mainly based on the light of these two colors, which are combined through different ratios. In terms of visual effects, the plant light with a combination of red and blue is pink; in terms of functional effects, blue light can promote the growth of green leaves; red light helps to bloom and prolong the flowering period!
When the LED plant light fills the plant with light, the height from the leaf is generally about 0.5 meters, and it can completely replace the sun if it is continuously illuminated for 12-16 hours a day. The function of LED plant light is very powerful when it is used for plant lighting, and the effect is very significant. The main functions of LED plant lights are reflected in the following points:
1. Reduce cultivation costs and extend flowering period;
2. Promote early maturity of plants, increase production, and improve the quality of melons and fruits;
3. Ensuring the taste of vegetables in greenhouses and realizing off-season cultivation;
4. Inhibit the reproduction of germs and pests, reduce the use of pesticides, and make it green without pollution.
The effect of LED grow lights on plants
Plant growth needs light for photosynthesis, but not all light is what plants need. Some friends must have tried to grow plants with fluorescent lamps and found that the growth of plants is not ideal or even withered, but the reason is not clear. Different wavelengths of light have different effects on plant photosynthesis. Plant photosynthesis requires light, and the wavelength is about 400-700nm. 400-500nm (blue) light and 610-720nm (red) contribute the most to photosynthesis. And the wavelength of fluorescent lamp is about 1000nm (white light) above, there is no light needed by plants, and photosynthesis cannot be carried out normally. Naturally, it cannot grow and develop normally.
The blue (470nm) and red (630nm) LED plant lights can just provide the light needed by plants. Blue light is helpful for plant photosynthesis, which can promote the growth of green leaves, protein synthesis, and fruit formation; red light can promote the growth of plant rhizomes, help flowering and fruiting and prolong the flowering period, and increase yield! So it is ideal The choice is to use a combination of these two colors. In terms of visual effects, the plant light with a combination of red and blue appears pink. The ratio of red and blue LEDs of LED plant lights is generally between 4:1--9:1, and 6-9:1 is usually optional. Different plants need different light ratios for growth. For example, stem and leaf plants need more blue light, and flower and fruit plants need more red light.
The effect of LED plant lights is very significant, and the growth rate is almost 3 times faster than that of ordinary plants that grow naturally. LED plant lights are generally suspended at a height of about 0.5-1 meters from the leaves, and they need to be continuously illuminated for 12-16 hours a day to completely replace the sun. In the winter when there is often no sunlight, the use of LED plant lights in greenhouses can also grow green vegetables, which can improve the sweetness of vegetables and fruits, reduce diseases and insect pests, and increase the yield by 30 to 50%.
The usefulness of LED plant lights is far more than that. The small family farm is just a small program for people's entertainment and leisure. This is just a small application of LED plant lights. Because of its remarkable characteristics and powerful functions, LED plant lights have a wide range of applications. They are mostly used in greenhouses, plant factories, greenhouse breeding, flower breeding, indoor gardens, water soluble breeding, pipeline cultivation, farms, potted plants, and spraying plants. Planting, tissue training, etc. It is suitable for any growth stage of plants, and is very effective for aqueous solution cultivation and soil cultivation.
