The light environment elements needed for plant production are light intensity, sunshine duration (light period for artificial light) and light quality. In the process of plant growth based on photosynthesis, light is undoubtedly very important, and light can also control plant morphogenesis based on light morphogenesis and the components contained in plants. Only by properly controlling these three factors can we cultivate high quality crops. Based on the application of artificial light in plant factory, this paper introduces the control technology of light environment and the characteristics of light source which can produce high quality crops.

 

 

According to the natural law of plant growth and the principle of plant photosynthesis by using sunlight, the light is used to replace sunlight to provide light source for plant growth and development. Light is closely related to the growth of crops. To give full play to the potential of plant photosynthesis is directly related to the benefits of agricultural production. In recent years, due to the promotion of market demand, greenhouse is widely used to produce anti season flowers, fruits, vegetables, etc. due to the short sunshine time in winter and spring, the growth of crops is slow, and the output is low, so it is urgent to supplement light.

 

 

 

The light in greenhouse is closely related to the growth of crops. To give full play to the potential of plant photosynthesis is directly related to the benefits of agricultural production. Room fill light, also known as plant fill light, is a kind of light fitting that uses light instead of sunlight to provide light source for the growth and development of greenhouse plants according to the natural law of plant growth and the principle that plants use sunlight for photosynthesis. Even under the condition of weak light, the growth of plants is weak and appears the phenomenon of excessive growth.
