Ventilation and heat dissipation should be the main factors during this period, and the cellar temperature should be controlled below 15°C.
Mid-term management: In the winter and winter season, the physiological activity of sweet potatoes decreased, and the breathing slowed down. The temperature and humidity of the cellar slowed down. As the temperature drops, the temperature in the pit decreases accordingly. At this time, the cellar shall be sealed in time to keep the cellar temperature within the safety range of 10-14°C.
