Plant lamp expansion application
- Sep 10, 2018 -

Plants rely on the energy of light for photosynthesis to grow, flower, and produce. However, due to the ever-changing climate change and illumination causes in nature, plants can not fully absorb the photosynthetic nutrients needed during their different growth periods, which brings disadvantages to growth, especially in the seedling stage. In this regard, scientific and rational artificial spectroscopy has created good absorption and reflection conditions for plant growth. The energy values of the blue zone and the red zone are very close to the plant photosynthesis efficiency curve (more significant for green plant efficiency) and are the best source of plant growth.

 

  In traditional agricultural production, general technical methods such as supplementing illumination with light source and applying different covering materials, such as monochromatic fluorescent lamps or colored plastic films, are used to change the light environment to regulate the growth and development of plants in the facility cultivation environment. The led plant growth lamp adopts different measures to avoid different degrees of problems, such as lack of analysis of specific spectral components, resulting in impure light quality, inconsistent light intensity, close to or even below the plant's light compensation point. The illumination source has low energy efficiency. A large number of application studies of LEDs in plant facility cultivation environments have shown that LEDs can solve these problems and are particularly suitable for use in artificial light-controlled plant facility cultivation environments.

 

  The LEDs in the field of plant culture also exhibit the following characteristics: the wavelength type is rich, which coincides with the spectral range of plant photosynthesis and photomorphology; the spectral wave width is half-width narrow, and can be combined to obtain pure monochromatic light and composite spectrum as needed; The light illuminates the crops evenly; it not only regulates the flowering and fruiting of the crops, but also controls the plant height and the nutrient composition of the plants; the system has less heat and takes up less space, and can be used in a multi-layer cultivation stereo system to achieve low heat load and production. Space miniaturization; in addition, its exceptional durability also reduces operating costs. Due to these remarkable features, LEDs are well suited for plant cultivation in controlled facility environments such as plant tissue culture, facility horticulture and factory seedlings, and aerospace ecological life insurance systems. As of 2013, China's facility horticultural area has developed rapidly, and plant light has promoted the light environment control lighting technology of plants.
