The application of LED in plant cultivation

As the fourth generation of new lighting sources, LED has many characteristics that are different from other electric light sources, making it the preferred energy-saving and environmentally friendly light source.
LEDs applied in the field of plant culture also exhibit the following characteristics: rich wavelength types, which exactly match the spectral range of plant photosynthesis and light morphology; The half width of the spectral wave is narrow, which can be combined as needed to obtain pure monochromatic light and composite spectra; Can concentrate specific wavelengths of light to evenly illuminate crops; Not only can it regulate the flowering and fruiting of crops, but it can also control plant height and nutrient content of plants; The system generates less heat and occupies less space, making it suitable for multi-layer cultivation and three-dimensional combination systems, achieving low heat load and miniaturization of production space; In addition, its strong durability also reduces operating costs. Due to these significant features, LED is highly suitable for plant cultivation in controllable facility environments, such as plant tissue culture, facility horticulture and factory seedling cultivation, and aerospace ecological life support systems.
