CARBON DIOXIDE APPLICATION SYSTEM AND CARBON DIOXIDE APPLICATION METHOD

摘要

In the present invention, a supply step in which a carbon dioxide supply device (10) is driven for two minutes (a predetermined first time) during which time an air circulation fan (31) is halted, and a dispersion step after executing the supply step in which the carbon dioxide supply device (10) and the air circulation fan (31) are halted for two minutes (a predetermined second time), are executed repeatedly in alternation, and if the temperature (T) within an agricultural house (AH) is at least T2 during the execution of the supply step or the dispersion step, the driving of the air circulation fan (31) is prohibited until the timing of the end of the following dispersion step.
