Application of LED in plant cultivation
Light environment is one of the important physical environmental factors indispensable for plant growth and development High-power LED lamp beads. Through light quality regulation, controlling plant morphology is an important technology in the field of facility cultivation. As a fourth-generation new type of lighting source, LED has many characteristics that are different from other electric light sources, as shown in Table (1), which also makes it the first choice for energy-saving and environmentally-friendly light sources High-power infrared lamp beads. The LED used in the field of plant cultivation also exhibits the following characteristics.The wavelength type is rich, which coincides with the spectral range of plant photosynthesis and light morphology, and the spectral wave width is narrow at half width High-power purple lamp beads. The wavelength of light irradiates the crops in a balanced manner, which can not only adjust the flowering and fruiting of the crops, but also control the plant height and the nutrient formation of the plants. The system generates less heat and occupies a small space. Miniaturization of the production space, in addition, its strong durability also reduces operating costs. Because of these remarkable features, LEDs are very suitable for plant cultivation in a controlled facility environment, such as plant tissue culture, facility gardening and factory seedlings, and aerospace ecological life support systems High-power LED.

2. Research on the application of LEDs to plant facility cultivation. In the past ten years, the area of facility horticulture in my country has developed rapidly, and the light environment control lighting technology for plant growth has attracted attention. Facility horticulture lighting technology is mainly used in two aspects: first, as supplementary lighting for plant photosynthesis when the amount of sunshine is small or short in sunshine time. Second, as the induction lighting for plant photoperiod and light morphology.

2.1 Research on LED as supplementary lighting for plant photosynthesis. Traditional artificial light sources generate too much heat. If LED supplementary lighting and hydroponic systems are used, air can be recycled, excessive heat and water can be removed, and electricity can be efficiently used. The land is transformed into effective photosynthetic radiation, and finally into plant matter. Studies have shown that the growth rate and photosynthetic rate of lettuce using LED lighting are increased by more than 20%. It is feasible to use LEDs in plant factories. Studies have found that compared with fluorescent lamps, mixed-wavelength LED light sources can significantly promote the growth and development of spinach, radish, and lettuce. Improved morphological indicators can maximize the bioaccumulation of sugar beets, the most significant accumulation of betanin in hair roots, and the highest sugar production in hair roots.
Divide and accumulate starch. Compared with the metal halide lamp, the anatomical morphology of the stems and leaves of the pepper and perilla plants grown under the LED with the corresponding wavelength changed significantly. As the optical density increases, the photosynthetic rate of the plants increases. LEDs with multiple wavelengths can increase the number of stomata in marigold and sage plants.

2.2 LED as a plant's photoperiod and light morphology, LEDs with specific wavelengths can influence the flowering time and quality of plants. Flower response regulates the length and flowering period of the pedicel, which is conducive to the production and marketing of cut flowers. It can be seen that the flowering and subsequent growth of plants can be regulated by LED regulation.

2.3 The application of LEDs in the research of aerospace ecological life support system. The establishment of a Controlled Ecological Life Support System (CELSS) is the fundamental way to solve the problem of long-term manned space life support. The cultivation of higher plants is an important component of CELSS. One of the keys is lighting. . Based on the special requirements of the space environment, the light source used in the cultivation of higher plants in space must have high luminous efficiency, the output light wave is suitable for plant photosynthesis and morphogenesis, small size, light weight, long life, high safety and reliability records, and no environmental pollution Features. Compared with other light sources such as cool white fluorescent lamps, high-pressure sodium lamps and metal halide lamps, LEDs are more effective in converting light energy into photosynthetically effective radiation. In addition, it has the characteristics of long life, small size, light weight and solid state, so in recent years It is highly valued in ground and space plant cultivation. Studies have shown that LED lighting systems can provide lighting with uniform spectral energy distribution, and the efficiency of converting electrical energy into light required by plants is more than 520 times that of metal halide lamps.
