METHOD AND DEVICE FOR CONTROL OF IRRADIATION OF PLANTS IN HOTHOUSE

摘要

Use: improves the quality of seedlings grown in the greenhouse, by optimizing the mode of irradiation of plants. SUMMARY OF THE INVENTION: Measuring the light level in a greenhouse with a sensor (brightness converter - pulse frequency) 9 in Day mode, set by timer 1. Automatically controls the level of illumination by means of artificial sources of visible light connected by the first actuator 11. Simultaneously during the day the value of the air temperature in the greenhouse is measured by the temperature sensor 12, this value is compared with the predetermined temperature reference 24 and if it exceeds the specified value The additions irradiate the plants by means of ultraviolet radiation sources connected by a second actuator 16. In addition, ultraviolet radiation sources are switched on in the Night mode when the air temperature in the greenhouse falls below a predetermined value. 2 sec. f-ly, 2 ill. sl fOfOEEl mgea -H / LJ-ji / rt WITH
