Due to the ever-changing climate change and light changes that often occur in nature, it is beneficial to growth, especially in the seedling stage. 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. People created scientific and reasonable artificial spectrum to produce 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. Aiming at the research of plant photosynthesis and the research and development of agricultural LED plant lamps, the company has established a professional plant planting laboratory to carry out scientific research on vegetables, fruits, medicinal materials and other plant species to achieve different plants and affect seedling and plant growth. The scientific research results of precise supplementary light application of plants in terms of light quality and wavelength.
For the past ten years. The light environment control lighting technology for plant growth has attracted attention. Lighting technology 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 photosynthesis of plants;
2. As the induced lighting for the photoperiod and light morphology of plants. If LED plant lights are used to supplement lighting and hydroponic systems, 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. And the growth and development of lettuce, improve the morphological index. 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.
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. 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. The production space is miniaturized; in addition, its exceptional durability also reduces operating costs.
Because of these remarkable features, LED plant lights are very suitable for plant cultivation in controllable facility environments, such as indoor flowers, facility gardening and factory seedlings, and aerospace ecological life support systems.
