The facility light environment is the most direct factor affecting photosynthesis and yield of crops and indirectly affects the quality of crops. Generally, the illumination intensity in the facilities is not lower than the light compensation point of crops, but the illumination intensity of the facilities is difficult to exceed the light saturation point of most crops due to the influence of a covering film, a building material framework and the like, and the fact that the illumination intensity is lower than the light saturation point of the crops permanently becomes a key factor for limiting the growth of the crops in the facilities.
