Provided is a multi-stage type cultivation apparatus comprising: an electric power supply unit for controlling electric power supplied from the outside to provide the electric power for the purpose of cultivating crops; a cultivation bed unit including a plurality of cultivation beds which are structured to be vertically spaced apart from each other and to be slantingly arranged to cross each other, so as to allow a culture solution to flow to the interior thereof, each of the cultivation beds having a groove in which crops are transplanted at every predetermined distance unit; a controller for receiving information on some or all of the temperature, the humidity and the CO2 concentration of a plant factory and controlling a cultivation environment of the crops on the basis of the received information and a predetermined cultivation condition; a water supply unit for providing, to the cultivation beds, the culture solution obtained by mixing supplied water and a nutrient solution at a predetermined ratio; and an illumination unit including one or more artificial light sources and controlling some or all of the wavelength, the intensity, and the irradiation period of the artificial light sources to irradiate light for cultivating the crops, wherein the controller stores learning data obtained by learning growth data according to a cultivation condition for each crop in the plant factory, estimates an optimal cultivation condition for cultivating a new crop on the basis of the learning data when the new crop is transplanted in the cultivation beds, and controls the cultivation environment on the basis of the estimated cultivation condition. |
