An air-blowing system for agricultural greenhouse designed to increase the internal temperature of a plastic greenhouse or glass greenhouse and heat and circulate interior air is provided to maintain the interior temperature necessary for plant growth and to prevent dew formation, thereby preventing the freezing damage to crops. An air-blowing system(100) for agricultural greenhouse comprises: an air-blowing device(10) on the upper side of a plastic greenhouse and an air inducing pipe(40) for inducing air on the lower side of the plastic greenhouse at the inlet part of the air-blowing device. A heating part(20) is installed at the outlet part of the air-blowing device to heat air by a heater and discharge to the upper side of the plastic greenhouse and has an insulating material at regular intervals on the interior of the heating part. The heater is installed on the exterior of the insulating material. |
