APPARATUS FOR CONTROLLING GROWTH RATE OF PLANT IN GREENHOUSE AND CONTROLLING METHOD THEREOF

摘要

PURPOSE: A greenhouse plant growth control device using a sunlight wavelength control, and a controlling method thereof are provided to adjust the growth speed of plants for the plant production quantity and shipping period control. CONSTITUTION: A greenhouse plant growth control device(200) determines the plant production quantity by the estimated production quantity information of a greenhouse, and the estimated quantity demand. The wavelength of sunlight to pass through a fuel-sensitive type panel(210) is selected by the determined plant production quantity. A wavelength control signal corresponding to the selected wavelength is offered to the fuel-sensitive type panel.
