Application Of Led In Plant Cultivation

Application Of Led In Plant Cultivation

Plants depend on the energy of light for photosynthesis to grow, flower and bear fruit. However, due to the ever-changing climate changes and light variations 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 reasonable artificial spectrum to plant growth to create a good absorption and reflection conditions. The energy values of blue and red regions, which are very close to the efficiency curve of plant photosynthesis (especially for green plants), are the best light sources for plant growth.

In traditional agricultural production, ordinary electric light source is generally used to supplement illumination and different mulching materials are applied, such as monochromatic fluorescent lamp or colored plastic film, to change the light environment to regulate the growth and development of plants in the facility cultivation environment. 

Led plant growth lamp adopts different measures from these measures, so as to avoid the existence of different degrees of problems, such as lack of analysis of specific spectral components, resulting in the treatment of light quality is not pure, light intensity is inconsistent, close to or even lower than the light compensation point of the plant, low energy efficiency of the irradiation light source. The results show that LED can solve these problems and is especially suitable for artificial light-controlled plant environment.
