The Fourth Generation of New Plant Lighting Light Source--LED Plant Lamp
As the fourth generation of new plant lighting source - LED plant lamp, LED has many characteristics different from other electric light sources before, which makes it the first choice of energy-saving and environmental protection light source. The LED used in plant culture also shows the following characteristics: abundant wavelength type, which coincides with the spectral range of photosynthesis and photomorphogenesis of plants; narrow half-width of spectral wave, which can combine pure monochrome light and composite spectrum according to needs; can focus on specific wavelength of light to irradiate crops equally; can not only regulate the flowering and Fruiting of crops, but also control them. Plant height and nutrient composition of plants; the system has fewer heat and occupies less space. It can be used in multi-layer cultivation three-dimensional combination system to achieve low heat load and miniaturization of production space. In addition, its strong durability also reduces operation costs. Because of these remarkable characteristics, LED is very suitable for plant cultivation in controllable facility environment, such as plant tissue culture, facility horticulture and factory seedling cultivation, and space ecological life-support system. Compared with traditional plant lamp, LED plant lamp has many advantages. Traditional artificial light source produces too much heat. For example, using LED supplementary lighting and hydroponic system, air can be recycled, too much heat and moisture can be removed, and electric energy can be efficiently transformed into effective photosynthetic radiation, and finally into plant material. The results showed that the growth rate and photosynthetic rate of lettuce increased by more than 20% under LED illumination. Mixed-wavelength LED light source can significantly promote the growth and development of spinach, radish and lettuce, and improve morphological indicators. It can maximize the biomass accumulation of sugar beet, the most significant accumulation of betaine in hairy root, and produce the highest accumulation of sugar and starch in hairy root. LED plant lamp can affect the plant growth cycle, and the specific wavelength of LED can affect the flowering time, quality and duration of plants. Some wavelengths of LED can increase the number of flower buds and flowers; some wavelengths of LED can reduce the flowering response, regulate the length of pedicels and flowering period, which is conducive to the production and marketing of cut peanuts. Thus, the flowering and subsequent growth of plants can be regulated by LED regulation. Product Application: Suitable for any growth period of plants, and effective for water solution culture or soil culture. Suitable for indoor gardens, potted plants, gardens, sowing, breeding, farms, spraying, greenhouse culture, water-soluble culture, flower culture, temperature
Room culture, pipe culture, etc.
