The benefits of LED plant light team plant growth
In traditional agricultural production, ordinary electric light sources are generally used to supplement the light and the application of different covering materials and other agricultural technical measures, such as the use of monochromatic fluorescent lamps and colored plastic films, and changing the light environment to regulate the growth and development of plants in the facility cultivation environment. LED plant lights adopt different measures to avoid problems of different degrees, such as lack of analysis of specific spectral components, resulting in impure light quality processing, inconsistent light intensity, close to or even lower than the light compensation point of plants , The low energy efficiency of the illuminating light source. A large number of research results on the application of LEDs in the environment of plant facility cultivation show that LEDs can solve these problems and are particularly suitable for applications in the environment of artificial light-controlled plant facility cultivation.
Plants rely on the energy of light for photosynthesis to grow, flower, and bear fruit. However, due to the ever-changing climatic changes and light changes in nature, plants cannot fully absorb the photosynthetic nutrients they need during different growth periods, which brings disadvantages to growth, especially in the seedling stage. Scientific and reasonable artificial spectrum creates 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), which is the best light source for plant growth.
All in all, red light can promote the rooting of chrysanthemum stems, the formation of chlorophyll, the accumulation of carbohydrates, and the absorption and utilization of carbohydrates. The use of red light plant lamps to supplement light in the process of rapid propagation has obvious effects on promoting the rapid rooting of various plants and improving the quality of seedlings.
Why can LED plant lights promote plant growth? In the process of plant growth and development, light has two functions. One is an indirect function, which is the photosynthesis mentioned above, and another direct function is the formation of light forms. The wavelength types of LED plant production lamps are rich, which coincides with the spectral range of plant photosynthesis and light morphology.
The spectrum has a narrow half-width and can be combined according to needs to obtain pure monochromatic light and compound spectrum. It can concentrate light of a specific wavelength to irradiate crops uniformly; not only can adjust the flowering and fruiting of the crop, but also control the height and nutrition of the plant Ingredients: The system generates little heat and occupies a small space. It can be used in a multi-layer cultivation three-dimensional combined system to achieve low heat load and miniaturization of production space.
The external environment affects the growth and development of plants, of which light has the greatest impact. The characteristics of full-spectrum LED plant lights: rich wavelength types, just in line with the spectral range of plant photosynthesis and light morphology; the half-width of the spectral wave width is narrow, and it can be combined as needed to obtain pure monochromatic light and composite spectrum.
Why LED plant lights can promote plant growth
Plant growth light organic planting is a kind of production that does not use chemically synthesized fertilizers, pesticides, growth regulators, genetic engineering and ion radiation technology, but follows the laws of nature, and adopts agricultural and physical and biological methods. To fertilize the soil, prevent and control diseases and insect pests, so as to obtain a safe agricultural production system of organisms and their products.
The effect of light on the plant (function: foil and setting off the main scene) is mainly in two aspects: on the one hand, light is necessary for the photosynthesis of green plants; on the other hand, light regulates the entire growth and development of plants in order to better adapt to the outside world environment of. This reliance on light to control the differentiation and structural and functional changes of cells will eventually inherit the formation of tissues and organs, and become light morphogenesis.
In the case of insufficient sunlight, LED plant lights simulate the most favorable wavelength of sunlight for plant growth. There are two main spectral regions absorbed by plant chlorophyll, one is the red part of wavelength 620~660nm, and the other is wavelength 430~ The blue part of 450nm, and the absorption spectrum of lutein and carotene is the blue part of wavelength 400~500nm. Lutein and carotene absorb blue light and transfer energy to chlorophyll for photosynthesis. Therefore, the main spectral regions that can be utilized by photosynthesis are the red part with a wavelength of 620 to 660 nm and the blue part with a wavelength of 400 to 500 nm.
To control the light distance, it is generally recommended that the top of the plant be controlled between 0.5M and 1M from the LED plant light. This distance not only allows the plant to receive sufficient light, but also the LED plant growth light can illuminate a wider area. At the same time, the height of the LED plant light should be appropriately adjusted according to the growth speed of the plant to control the LED plant growth light to be in the most reasonable light supplement position.
The number of lamps is controlled. The degree of supplementary light required by plants in each growth stage is different. The light required during the germination and seedling period is not very strong. The distance between the plant lights can be increased, the number of LED plant lights can be reduced, and electric energy can be avoided. The waste; when the plants bloom and bear fruit, the required light will increase. At this time, use the LED plant growth lamp to supplement the light according to the best supplement light plan budgeted at the time of ordering.
For the control of light time, plants are also alive and need to rest. It is also very important to reasonably control the time for LED plant lights to fill the plants with light, generally no more than 16 hours. More than a lot, plants cannot rest normally, which affects the synthesis of organic matter that affects respiration. Needless to say, the time is too short. Since you have purchased LED plant lights, you know the reasons.
