Science about plant wavelengths
1. The color temperature and lumen of the plant lamp The color temperature and lumen of the plant lamp are seen from the human eye, and the photosynthesis of the plant against light does not look at color temperature and lumens.
2, the spectral range of plant physiology effects 280 ~ 315nm - the impact on morphology and physiological processes is very small 315 ~ 400nm - less chlorophyll absorption, affecting the photoperiod effect, preventing stem elongation 400 ~ 520nm (blue) - chlorophyll The ratio of carotenoid absorption is the largest, and the effect on photosynthesis is 520 ~ 610nm (green) - the absorption rate of pigment is not high 610 ~ 720nm (red) - the chlorophyll absorption rate is low, which has a significant effect on photosynthesis and photoperiod effect. 720 ~ 1000nm - low absorption rate, stimulate cell elongation, affect flowering and seed germination >1000nm - conversion to heat From the above data, different wavelengths of light have different effects on plant photosynthesis, plant photosynthesis needs The light has a wavelength of around 400 ~ 720nm.
Light from 400 to 520 nm (blue) and 610 to 720 nm (red) contribute the most to photosynthesis. Light from 520 to 610 nm (green) is absorbed by plant pigments at a very low rate.
3. According to the above principle, the plant lights are made into a combination of red and blue, all blue, and all red, to provide red and blue wavelengths of light, covering the wavelength range required for photosynthesis. In terms of visual effects, the red and blue combination plant lights appear pink.
The white light LED lamp, the most common is to use the blue core to stimulate the yellow phosphor, which combines to produce a visual white light effect. In the energy distribution, there are two peaks in the blue region of 445 nm and the yellow-green region of 550 nm. The 610 ~ 720nm red light required by plants is very scarce. This explains why plant growth is not good under white LED illumination.
4, the red and blue light chromatogram ratio of the plant lamp is generally between 5:1 ~ 10:1, usually 7 ~ 9:1 ratio.
5. When the plant light is used to fill the plant, the height of the blade is generally about 0.5 meters.
Application case: The experts of Agricultural University cultivated a batch of wintergreen seedlings through cloning technology, and based on their growth status under different color light sources, find the "nutrition light" which is most suitable for plant growth. Remember to see that the holly seedlings in purple light are the tallest, but the leaves are small, the roots are shallow, and a malnutrition looks like. The seedlings under the yellow light are not only short, but the leaves look lifeless. The holly growth that grows under the mixed light of red and blue is the best, not only strong, but also very developed. According to reports, the red and blue bulbs of this source are configured in a 9:1 ratio. In addition to the holly seedlings, the experts also conducted a light test using Phalaenopsis, Oncidium, Strawberry, and Tomato. The results show that a 9:1 red-blue light is most beneficial for plant growth.
Since blue is good for plant leaf growth, red is good for plant flowering and fruiting, so the number of red and blue lamp beads in this lamp can be specially made according to the user's plant requirements for light.
There are four forms of light and plant light affecting plants: light quality, photoperiod, light intensity, and light quantity. Plant growth and yield (plant size, number of flowers, and other characteristics) are mainly absorbed by the entire day. The influence of plant morphology (height and plant type) is mainly related to light quality (mainly blue light, red light,). For photoperiod sensitive plants, flowering (short-day and long-day plants) is mainly affected by the duration of light or photoperiod, while the photoperiod-insensitive plants (neutral) have the greatest influence on the amount of light, and photosynthesis is mainly affected by light and light. Strength effect. Photosynthesis mainly occurs in the visible spectrum, (400-700nm)
The strongest LED plant growth lamp in the red light region and the blue light region is based on the growth mechanism of plant photosynthesis, using LED as the light source, mixing according to the scientific RB ratio, and synthesizing the necessary plant growth. Light, spectrally pure, the spectrum is concentrated at 450-470, 615-625. Compared with ordinary plant lights, the advantages are obvious. Ordinary plant lamps radiate ultraviolet and infrared light that are useless to plant growth, and waste a lot of electric energy. LED plant growth lamps use electroluminescence mechanism. Under the same light intensity, LED plants The growth lamp saves more than 80% of electricity than ordinary plant growth lamps.
The life of ordinary plant lights is generally only 1000-5000 hours, while the life of LED plant lights can reach 100,000 hours. Long-lasting, energy-saving, high utilization of light energy, no light that is ineffective for plant growth, is a real promotion of plants. Growing professional lighting products!
Balcony agricultural technology integrating modern agricultural achievements
The 21st century is a century of the development of balcony agricultural science and technology explosion. In this great era, various fields have undergone ever-changing changes, that is, the inconspicuous balcony or the corner of the roof has changed, and it is profound. The qualitative change. The original bare reinforced concrete floor can now be covered with green clothes. The roof that was originally lifeless and even smoked in summer can now bring coolness to the cool department. The original chaotic and disorderly roof balcony greening It has become a well-organized and systematically designed system engineering. It has become more professional, more popular, and more simple. This is the result and combination of modern technology and balcony agriculture.
In the balcony greening, you can integrate all the high-tech of agriculture. The balcony is no longer the epitome of traditional farming but the integration of agricultural high-tech. Because it is important to people's life and plays an important role in the hunger of human environment. It is no longer a green onion, garlic and green vegetables, but a pot of vegetables and a wooden box, but through scientific planning and design; and no longer watering the seedlings in the morning and evening, pulling the grass to promote growth, fertilizing and fighting drugs to form a group The management model, but the use of modern computer intelligence technology to achieve the operation of fools, everything becomes simple, as long as you plant seedlings, waiting to appreciate and harvest.
You are the busiest workaholic who can manage balcony agriculture as well. You don't have to spend a lot of energy on a large area. It is a real space for you to relax and adjust your mood and find a sense of returning to nature. An important project of the urban vegetable basket, its output is several times that of the cultivated balcony agriculture, even ten times. Its quality is more tender and sweet than the taste of soil cultivation. It is a micro base for the production of pollution-free vegetables. Cultivating a cultivated area of about 2-5 square meters is available for the fruits and vegetables of your family of three. So what are the advantages of this new type of balcony agriculture technology and what modern high technology is integrated to make it unique and become a beautiful landscape of urban construction?
