Question 1: How do families store sweet potatoes in winter? Storage of sweet potatoes in winter can last for several months as long as you master the following points.

First, sweet potatoes should be selected: sweet potatoes that have just been recovered from the ground should be selected for storage, and there should be no frostbite, deterioration or potato damage. Generally, sweet potatoes bought in the northern market will have frostbite (it is difficult to find by visual inspection).

The second is to control the temperature: the most important part of sweet potato storage is the temperature link. The temperature can only be between 9- 14 degrees. When the temperature is high, it will sprout, and when the temperature is low, it will rot.

Third, can't put it in a ventilated place: just can't have through flow, and the sweet potato blown by through flow is easy to rot for a long time.

In fact, it is ideal to put it in the underground kiln, but there are fewer underground kilns on the edge of the city. Generally, it is enough to put it in a cool place with cardboard boxes.

Question 2: Home preservation method of sweet potato 1) Indoor preservation method Sweet potato is very afraid of cold. If the temperature is too low, it may freeze, form a hard core and cook badly. If the temperature is higher than 18 degrees Celsius for a long time, it will germinate again. Therefore, it is best to control the room temperature at about 15 degrees Celsius. At the same time, we should also pay attention to prevent the temperature from rising and falling. Sweet potato is moist, which easily leads to the invasion of germs and causes rot.

So it's best to keep it in a breathable wooden box. If there is no wooden box, put a wooden board near the wall where the sweet potatoes are stacked, and cover something on the potato pile to prevent moisture. In warm days, it is necessary to properly open the window for ventilation to keep the indoor air fresh, but to prevent cold air from blowing in.

In addition, some sweet potatoes sold in the market will be crushed and bruised after transportation, and germs will easily invade and lead to rot. Therefore, it's best to put the bought sweet potato in the sun for several hours (don't leave it outside for the night) to reduce the moisture of the wound and promote healing, and handle it with care to avoid bumping.

2) After steaming, dry the sweet potato and store it. After steaming, cut each piece into three or four pieces and put it indoors or in a sunny, dry and ventilated place to dry. After the sweet potato is steamed, the water evaporates slowly and it takes a long time to dry thoroughly. Be careful not to get caught in the rain. After drying, store it in a dry place indoors. Soak and steam before eating.

Spraying 1% copper sulfate solution or 50 times of formaldehyde solution in the cellar, or mixing formaldehyde with potassium permanganate, and sealing and fumigating. After the sweet potato enters the cellar, it is forbidden to seal the cellar prematurely, pay attention to ventilation and heat dissipation, and prevent the cellar from burning. Keep the temperature at 65438 05℃ to 20℃ and the relative humidity at 90%. After the winter solstice, cold waves are frequent and the temperature is low. Therefore, attention should be paid to heat preservation and cold prevention, and it is appropriate to keep the temperature of the pit at about 12℃ to 13℃.

After beginning of spring, the weather is hot and cold, and the temperature is changeable. At this time, the sweet potato began to sprout, its resistance weakened and it was easy to rot. Therefore, when the weather gets warmer, it is necessary to ventilate and cool down in time.
