After application tests, the plant light is very suitable for the growth, flowering and fruiting of plants. Generally, indoor plants and flowers will grow worse with time due to lack of natural light. By using plant lights with the required spectrum of plants, not only can they promote their growth, but they can also prolong the flowering period and improve the quality of the flowers. The application of this high-efficiency light source system to agricultural production such as greenhouses, greenhouses and other facilities on the one hand can solve the shortcomings of the lack of sunlight that causes the taste of tomatoes, cucumbers and other greenhouse vegetables to decrease, and on the other hand, it can also make winter solanum vegetables in advance. It will be listed around the Spring Festival, so as to achieve the purpose of off-season cultivation.
(1) As an artificial supplementary lighting, the lighting can be enhanced at any time from 5 in the morning to 23:00 in the evening, and the effective lighting time can be extended.
(2) Regardless of whether it is sunny, cloudy, or rainy, the light required by plants can be reasonably and effectively extended and scientifically controlled, as long as you have mastered this light supplement product and product application technology.
(3) In the greenhouse or plant laboratory, it can replace natural light to ensure healthy plant growth and promote better plant growth.
Light environment is one of the important physical environmental factors that are indispensable for plant growth and development. Through light quality regulation, controlling plant morphology is an important technology in the field of facility cultivation.
Application of LED in plant cultivation
As a fourth-generation new type of 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 LED used in the field of plant cultivation also exhibits the following characteristics: rich wavelength types, just in line with the spectral range of plant photosynthesis and light morphology; narrow spectrum wave width half-width, can be combined as needed to obtain pure monochromatic light and compound spectrum; can be concentrated The specific 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 a low heat load And the 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 seedling breeding, and aerospace ecological life support systems.
