1, cellar preservation, in rural areas, a big pit will be dug underground, and then sweet potatoes will be put in, covered with a layer of plastic sheets and leaves, so that sweet potatoes can be preserved for a long time.

But there is no cellar in the city. I'll teach you another trick After cleaning up the soil of intact sweet potatoes, we put them in a dry box and put them all away. Finally, we put an apple in a sealed carton and put it in a cool and ventilated place. This will not germinate for a long time and will not affect the taste of sweet potatoes.
