2. Storage method of sweet potatoes:

Indoor storage: Sweet potatoes are afraid of cold. When the temperature is too low, they will freeze and form a hard core.

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.

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.

(3) Slice and dry storage method: Slice the sweet potatoes and put them on the house or in a sunny, dry and ventilated place to dry. Be careful not to get wet with rain or snow. After drying, store it in a dry place indoors and soak it in water before eating.
