Compared with the control of light intensity, the control of light time is easier. In the production of solar panel greenhouses, the light time is generally controlled according to the types of plants, and the light time is also adjusted by intermittent supplementary light or shading. Appropriately reducing the light intensity to extend the light time, increase the proportion of scattered radiation, intermittent or weak light alternation, etc. can greatly improve the light utilization efficiency of plants
1 Fill light of photoperiod
For crops that are sensitive to the photoperiod, when the night time is too long and affects the growth and development of the crops, the artificial period should be supplemented with light. Artificial periodic light supplementation is provided as information for regulating the growth and development of crops. It is generally used to promote or inhibit the differentiation of flower buds of crops and adjust the flowering period. Therefore, the requirement for supplementary light intensity is not high. The time and intensity of supplementary light is the type of plant Depends.
2 photoperiod shading
The purpose of the photoperiod shading is to extend the concealed device, to ensure that the short-day plants require continuous dark periods to regulate flower bud differentiation. Usually, black cloth or black plastic film is used to cover the top and surrounding of the crop tightly. During the photoperiod shading period, ventilation should be strengthened to prevent the occurrence of high temperature and high humidity environment from harming plants.
