Plants cannot fully absorb the photosynthetic nutrients they need during different growth periods in different growth periods. Plants rely on the energy of light for photosynthesis to grow, flower, and bear fruit. However, due to the ever-changing climate change and light changes often occur in nature. It is beneficial to growth, especially in the nursery stage. In this regard, scientific and reasonable artificial spectrum invented good absorption and reflection conditions for plant growth. The energy values of the blue light zone and the red light zone are very close to the efficiency curve of plant photosynthesis (and the efficiency is more significant for green plants) the best light source for plant growth. The company’s LED plant growth lamp simulates natural light, and can also produce red and blue light mixed products according to customer needs to provide an accurate spectral range for the photosynthesis of plants. It is suitable for all stages of plant growth. The growing application plant lamp is suitable for soilless cultivation or soil cultivation in any indoor garden. At the same time, we can also provide customized plant growth lighting solutions according to customer needs.
The area of national facility horticulture has developed rapidly in the past ten years. The light environment control lighting technology for plant growth has attracted attention. The lighting technology of facility horticulture is mainly used in two aspects:
1. When the amount of sunshine is small or the sunshine time is short, it can be used as supplementary lighting for plant photosynthesis;
2. As the induced lighting for the photoperiod and light morphology of plants.
If LED supplementary lighting and hydroponic systems are used, air can be recycled, excess heat and water can be removed, and electrical energy can be efficiently converted into effective photosynthetic radiation, and finally into plant matter. The study showed that the use of LED lighting can increase the growth rate and photosynthetic rate of lettuce by more than 20%. It is feasible to use LED plant lights with factories. The study found that compared with fluorescent lights, the wavelength of LED plant lights can significantly promote spinach and radish. The growth and development of lettuce and lettuce can improve the morphological index; it can maximize the bioaccumulation of sugar beet, the most significant accumulation of betain in the hairy root, and the highest sugar and starch accumulation in the hairy root. Compared with metal halide lamps, pepper and perilla plants grown under LEDs that match the wavelength have significant changes in the anatomical morphology of their stems and leaves. Any plant needs sunlight to grow and grow as the light density increases. The photosynthetic rate increases. LEDs with multiple wavelengths can increase the number of stomata in marigold and sage plants.
LED plant lights are one of the important physical environmental factors that are indispensable to promote plant growth and development. Through light quality regulation, controlling plant morphology is an important technology in the field of facility cultivation. As the fourth-generation new lighting source, LED has many characteristics that are different from other electric light sources, which also makes it the first choice for energy-saving and environmentally friendly light sources. The LEDs used in the field of plant cultivation also show the following characteristics: rich wavelength types, just in line with the spectral range of plant photosynthesis and light morphology; the spectral wave width is narrow at half width, and can be combined according to needs to obtain authentic monochromatic light and composite spectra, which can focus on specific The wavelength of light irradiates the crops in a balanced manner; not only can adjust the flowering and fruiting of the crops, but also control the plant height and the nutrients of the plants; the system generates less heat and occupies a small space. It can be used in a multi-layer cultivation three-dimensional combination system to achieve low heat load and The production space is miniaturized; in addition, its strong durability also reduces operating costs. Because of these remarkable characteristics, LEDs are very suitable for plant cultivation in controlled facility environments, such as indoor flowers, facility gardening and factory seedlings, and aerospace ecological life support systems.
