Illumination is an indispensable condition for root healing and normal development of cuttings. On the one hand, living cuttings require photosynthetic synthesis of the necessary nutrients for rooting. On the other hand, sunlight is also an important factor in regulating temperature in arch shelters. Illumination is an indispensable condition for root healing and normal development of cuttings. On the one hand, living cuttings require photosynthetic synthesis of the necessary nutrients for rooting. On the other hand, sunlight is also an important factor in regulating temperature in arch shelters. Strong light can cause high temperatures. Low light, such as long time, will cause cuttings and cuttings to rot. Therefore, adjusting the light intensity is an important part of arched seedling management. All-optical spray nursery because the temperature is mainly regulated by the spray, there is no regulation of light problems, the regulation of lighting on the shed mainly depends on the shading curtain transmittance adjustment. Transparency should change with the season, weather (yin, sunny), the solar altitude and other conditions, generally less light in the fall, and winter and spring more. During the day from 10 a.m. to 4 p.m., when the sun is at a high angle, it can be shaded. During the rest of the day, shades can be removed. Cloudy and rainy days can also be uncovered. At different stages of rooting, the light transmittance should also be changed. The initial light transmittance should be smaller, and the light transmittance at the later stage of rooting can be greater.
