Storage methods of sweet potatoes:

Storage in well cellars: Choose a place with high terrain, solid soil, and low underground water level, and dig a wellbore downward, usually about 1 meter in diameter and deep. 5~6 meters. The size of the storage room can be determined according to the amount of storage. The storage room should be padded with 10 to 15 centimeters of dry sand, and sweet potatoes should be placed on it. Sweet potatoes can only be filled 70% full to allow room for ventilation, otherwise moisture and heat will aggravate rot.

Cellar storage: Generally, a cellar is dug about 2 meters wide, 3 to 4 meters long, and about 2 meters deep. Stack the sweet potatoes piece by piece from bottom to top, avoiding direct contact between the sweet potatoes and the cellar wall.

Root cellar storage: The structure of a cellar is similar to that of an ordinary house, but the walls and roof are very thick, the surroundings are sealed, the windows are open, and there are fire channels for heating, so that high-temperature healing can be performed. There are two types of cellars: large cellars (storing 10,000 to 50,000 kilograms) and small cellars. Small cellars are small, save labor and materials, and are suitable for storage by farmers. Generally, each cellar can store 1,500 to 3,000 kilograms.

Indoor storage method: Sweet potatoes are afraid of cold. When the temperature is too low, they will freeze and form a hard core. They will not be steamed or cooked well; if the temperature is too high, they will sprout again and eventually It is best to control the room temperature at around 15℃. If sweet potatoes are damp, they can easily be invaded by pathogens and cause rot. It is best to store them in a breathable wooden box. If there are no wooden boxes, wooden boards should be placed where the sweet potatoes are stacked and against the wall, and the potato pile should be covered with something to prevent moisture. During the warm day, windows should be opened appropriately for ventilation to keep the indoor air fresh and prevent cold wind from blowing in. It is best to put the sweet potatoes bought from the market in the sun for a few hours to reduce moisture in the wound and promote healing. When handling it, handle it with care to avoid bruises.
