简介 PROBLEM TO BE SOLVED : To provide a blowing method intended for solving such problems that a conventional frost damage protection method comprises a system appropriately controlling a heater/a blower on the basis of a set temperature to be maintained around crops for frost damage protection and a temperature around crops, but the system is not a method which catches natural durability which crops have and is required for growth, and has a problem of possibly killing through excessive growth characteristics which this kind of crops has, and the operation of a heater has a problem of destruction of the earth environment by occurrence of exhaust gas. SOLUTION : This blowing method comprises setting an H sensor on an inversion layer and an L sensor on a leaf surface, setting conditions of blowing down warm air of the inversion layer to the crops in such conditions that a temperature of the inversion layer is higher than that of a position easy to receive frost damage, and the temperature difference is about 0.5°C-about 1.0°C, continuing blowing even after detection of the temperature of frost damage with the L sensor, gradually performing melting, and using a frost protection fan which avoids cytoclasis of the leaf surface of crops.
