摘要
A frost protection apparatus (1-1) is provided with: a frost protection fan (11) which is disposed at a height at which an inversion layer (X) is generated in an agricultural field and sends air down to the agricultural field; a power generator (15) which is a drive source for the frost protection fan (11); a temperature sensor (12) for detecting the temperature of or near the surface of a leaf of a crop (A) in the field; a control device (14) for transmitting an operation signal for operating the power generator (15) on the basis of a detection value from the temperature sensor (12); and a battery (18) for supplying power to the control device (14). When the control device (14) transmits the operation signal to the power generator (15) and receives a power generation establishment signal from the power generator (15), the control device (14) supplies power from the power generator (15) to the frost protection fan (11).
