The invention belongs to cultivation equipment in the agricultural engineering field, which comprises an ultrasonic atomizer, an atomization chamber, a water storage tank, an axial-flow fan, a solenoid valve, a water level detection sensor, a control box, a fog conveying and nutrient solution return pipe, a cultivation box, a cultivation plate and a bracket. The cultivation device can perform aeroponic cultivation and water cultivation simultaneously, and is characterized in that fog drops enter the cultivation box under the wind action, the unabsorbed nutrient solution is deposited in the cultivation box and kept at a stable height, and the cultivation device can also ensure the height of the nutrient solution in the atomization chamber to be kept at a proper position, so that the ultrasonic atomizer can work at the maximal efficiency. The cultivation device has the advantages of sufficient oxygen gas for the crop root system in aeroponic cultivation and rapid production, can ensure the normal growth of crops in case of power-off or device failure, and can provide crops with sufficient water and nutrient through water cultivation when fog drops are hard to reach the interior of a dense root system or fog drops can not provide sufficient nutrients required for the plant growth.
