Plants rely on the energy of light for photosynthesis to grow, bloom, and the result. However,  due to the ever-changing nature of the ever-changing climate change and  light variations, plants can not fully absorb the photosynthetic  nutrients they need during different growth periods in different growth  periods, which is unfavorable for growth, especially in the seedling  raising stage. In  this regard, scientific and rational artificial spectrum of plant growth  has created a good absorption and reflection conditions. The energy values of the blue and red regions are very close to  the efficiency curves of photosynthesis of plants (more so for green  plants) and are the best sources of plant growth.
 
  
In  the traditional agricultural production, ordinary electric light  sources are used to supplement lighting and apply different covering  materials and other agricultural technical measures. For example,  monochromatic fluorescent lamps or colored plastic films are used to  change the light environment to control the growth and development of  plants in the facility cultivation environment. LED  plant growth lamps use different measures to avoid the existence of  varying degrees of problems, such as the lack of analysis of specific  spectral components resulting in impure processing of light quality,  light intensity inconsistencies, close to or below the plant's light  compensation point , Low energy efficiency of light irradiation. The large number of LED applications in plant cultivation  environment research results show that LED can solve these problems,  especially suitable for artificial light control plant cultivation  environment.
 
  
The  LED in plant cultivation also shows the following characteristics: rich  wavelength type, coinciding with the spectral range of plant  photosynthesis and light morphogenesis; narrow half-width spectrum wave  width, pure monochromatic light and composite spectrum can be obtained  as required; Which  not only can regulate the flowering and fruiting of crops, but also can  control plant height and vegetative components of plants; less system  fever and small occupation space, and can be used for multi-layer  cultivation stereo combination system to achieve low heat load and  production Space miniaturization; In addition, its extremely strong durability also reduces operating costs. Due  to these salient features, LEDs are well suited for plant cultivation  in controlled facility environments such as plant tissue culture,  facility horticulture and industrial nursery and aerospace biosecurity  systems. By  2013, the area of horticultural facilities in our country has been  developing rapidly. Plant lighting technology has been paid attention to  in light environment control of plants.
