Application of LED plant lamp in cultivation

LED plant growth lamp or light simulate natural light, can also according to customer demand production of red and blue light products, for the photosynthesis of plants to provide accurate spectral range, suitable for plant growth stages of plant growth LED lights in the application of plant growth lamp is suitable for any indoor garden plants soilless cultivation or soil cultivation. At the same time, we can also provide customized plant growth lighting solutions according to customers’ requirements.

National facilities horticultural area developed rapidly in the last decade. Light environment control lighting technology for plant growth has attracted much attention. Facility horticultural lighting technology is mainly applied in two aspects:
I. When the amount of sunshine is low or the duration of sunshine is short, it serves as supplementary illumination for plant photosynthesis;
Ii. Induced illumination as plant photoperiod and photoperiod.

With the use of LED supplementary lighting and hydroponic systems, air can be recycled, excess heat and water removed, and electrical energy can be efficiently converted into photosynthetic radiation, and ultimately into plant matter. The study indicates that the growth rate and photosynthetic rate of lettuce can be increased by more than 20% by using LED lighting. It is feasible for LED plant lamps to be used in factories. The study finds that, compared with fluorescent lamps, the light source with the wavelength of LED plant lamps can significantly promote the growth and development of spinach, radish and lettuce and improve the morphological indexes. Beet bioaccumulation was the highest, betet accumulation was the most significant in hair root, and sugar and starch accumulation were the highest in hair root. Compared with metal halide lamps, pepper and Perilla plants growing under the same wavelength LED have significant changes in the anatomical morphology of their stems and leaves. Any plant needs sunlight to grow, and with the increase of light density, the plant’s photosynthetic rate increases. The compound wavelength LED can increase the number of stomata in marigold and sage plants.

LED plant lamp is one of the important physical environmental factors indispensable to plant growth and development. Controlling plant morphological formation through light quality regulation is an important technology in the field of facility cultivation. As the fourth generation of new lighting source, LED has many characteristics different from other electric light sources, which also makes it the first choice for energy saving and environmental protection. Leds used in plant culture also show the following characteristics: rich wavelength types, which coincide with the spectral range of plant light synthesis and light morphogenesis; The width of spectrum wave is half width and narrow, and the combination of tunnel monochromatic light and composite spectrum can be obtained according to the need, and the light of specific wavelength can be concentrated to evenly illuminate the crops. It can not only regulate the flowering and firmness of crops, but also control plant height and plant nutrition. The system has less heat and occupies less space, which can be used for multi-layer cultivation and three-dimensional combination system, realizing the miniaturization of low heat load and production space. In addition, its especially strong durability also reduced the operation cost. Because of these remarkable characteristics, LED is very suitable for plant cultivation in controlled facility environment, such as indoor flowers, facility horticulture and factory seedling cultivation, and aerospace ecological health and conservation system.
