How can sweet potatoes be preserved longer in rural areas?

Most of the sweet potatoes in the countryside are placed in the cellar, because the cellar is cold and damp, like a homemade refrigerator, you can store the sweet potatoes for a longer time and keep the sweet potatoes fresh.

Put the sweet potatoes in the cellar in the countryside. Because the environment in the cellar is very cold. It won't let the sweet potatoes catch the wind yet. Therefore, it is very convenient to preserve sweet potatoes in rural areas.

The harvest period of sweet potatoes is closely related to safe storage, if the harvest is too early, the temperature is still high, and the cellar can not be stored in time after harvesting; However, if the harvest is too late, during the frost period, and the night temperature is very low, chilling injury may occur. Therefore, when the temperature drops to 15 degrees, the terrain is high and convex, sheltered from rain and moisture, and the sun is abundant. The excavation is one person high, three to four meters deep.

Drill down a cellar to hide thousands of catties of red heat. With the improvement of living standards, a large number of laborers went out, and the number of sweet potatoes and cellars gradually decreased.

The traditional storage method is to dig a cellar on the ground, the size of the cellar is proportional to the sweet potatoes to be stored, the sweet potatoes that need to be stored are cooled and sunned, the soil is cleaned, and the cellar is stored, the depth of the cellar is suitable for the sweet potatoes not to be damaged by frost, so that the storage of sweet potatoes is still breathing, simply put, it is to dig a well 3 4 meters deep underground, and then go out of the hole horizontally at the bottom of the well, so that the temperature in the hole can be kept at about 4 degrees Celsius, and the sweet potatoes can be stored for a long time after being put in, so as to achieve the purpose of not freezing.

If you want to keep sweet potatoes for a longer time, it is best to choose sweet potatoes that have been recovered from the ground for storage, sweet potatoes can not have frostbite, deterioration and potato body damage, this kind of sweet potatoes are very perishable. Second, we must control the temperature and dig the earth well at least 4 meters deep, and then dig a horizontal hole 1 meter high, 1 meter wide and 2 to 3 meters long. Add the sweet potatoes and seal tightly with fine sand.

The wellhead is open, and there is a vent at the cover wellhead in severe winter. Take as you go, and cover tightly with sand after taking it. By the next year, the new potatoes will not be bad when they go down the well!

The sweet potato harvest time is usually from September to October every year, and the best harvest time is September, if the time is determined by 24 solar terms, frost is the cut-off point, and harvesting sweet potatoes later than frost will reduce the quality of sweet potatoes, and it will rot in the cellar if it is not rotten in the ground. Therefore, autumn vitamins, amino acids and other minerals in the countryside have the reputation of "longevity food". It can detoxify, assist in lowering blood pressure and anti-aging.

It has a miraculous effect on the prevention of emphysema, diabetes, and obesity.

In the southern region, harvested sweet potatoes are often placed on the floor of a firewood house, where firewood is often burned. Such sweet potatoes can be smoked often and kept dry for a long time, and there are very few rats in such places. Sweet potatoes have less moisture and are easier to store after drying on top for a while.

This method is common in many rural areas, and you can try it if you can.

In rural areas, sweet potatoes are kept longer in this way, and in rural areas, sweet potatoes are generally placed in the cellar, because the temperature in the cellar is low, there is no sunlight, and sweet potatoes can be stored for a long time, but remember not to put sweet potatoes together and cover them with plastic sheets, which will make the sweet potatoes rot, and the sweet potatoes must be separated, and a part of the sweet potatoes can be used to make dried sweet potatoes for storage, so that the sweet potatoes can be stored for a long time.

Generally speaking, it is enough to put it in the cellar, and the cold temperature can keep the sweet potatoes for a longer time.

When storing, do not put the sweet potatoes in a cool and humid environment, take the sweet potatoes to the sun for a period of time to dry for a period of time, and the sweet potatoes should be brought back with a layer of mud on the surface, so that they can be stored for a long time.

In the countryside, sweet potatoes do not rot for a long time and do not sprout, sweet potatoes taste very soft and glutinous and sweet, and its cellulose content is very rich, which is very beneficial to our intestines. Sweet potatoes are delicious whether they are steamed or roasted, but many people don't know how to preserve them. Here are some ways to preserve sweet potatoes.

In the case of too many sweet potatoes at home, we can take into account the sweet potatoes to dry and carry out storage, in autumn and winter, the home is easy to get wet and cold, if the sweet potatoes are stacked in the corner for a long time, there will be mold, if you want to store them for a long time, you must put them in the sun to dry, October is the season when many sweet potatoes are on sale, and the sweet potatoes you buy must not be in a hurry to become larger, and the refrigerator should be stored in the refrigerator to be dried under natural ventilation, so that the sweet potatoes can be stored for a long time.

In fact, I feel that this way is more easy to use, because the indoor space at home is not large, if the sweet potatoes are paved to carry out storage, it is not clean and occupies the area, in fact, the best use of the carton box is that it can be damp, in the bottom box, we pave a layer of newspapers, in the neat sweet potatoes placed on the last time, so that the storage can be carried out with adhesive tape and sealed up to the natural ventilation of the part, so that the sweet potatoes are not easy to sprout, and it is relatively easy to store.

Many people have the same idea as me, that is, the colder the sweet potato is stored in the area, the less likely it is to be damaged, in fact, this is also the idea of asking for trouble, last year I put the sweet potato in the veranda at home to store, after steaming out the sweet potato core is very hard and the taste is also very poor, so you should put it in a cool and dry area at room temperature.

In fact, there is also a way to use sand and soil to carry out storage, now everyone settles in the house, there are many good soil and sand, so the small yard of the family can dig a hole and put the sweet potatoes in the soil, in the cover of a layer of sand, so that the sweet potatoes taste sweeter when eating, and can be stored for more than half a year without worrying about damage.

When we store sweet potatoes, we must choose those whole, no traumatic sweet potatoes, sweet potatoes on the surface of the sweet potatoes can also not be removed, which can play a protective role in the sweet potatoes, and appropriately reduce the loss of water and nutrients in the sweet potatoes.

Although sweet potatoes are more resistant to storage, but when preserving, we should also pay attention to temperature and humidity, generally speaking, sweet potatoes like temperature and do not like freezing, according to the data, the best temperature to preserve sweet potatoes is about 0 to 15 degrees, if the temperature is too low, sweet potatoes are easy to frostbite and rot.

After the sweet potato is harvested, after drying for 3 5 days, the farmer growers should be packaged with bran husk or corn husk, a layer of bran, a layer of sweet potatoes, and sweet potatoes in the same layer, which should be separated by bran husks. Or spread a layer of dried fine sand under the cellar, and stack the sweet potatoes in layers, taking care not to have too many layers, and leave room for ventilation.

2. Indoor storage.

Law. Sweet potatoes are afraid of cold, and when the temperature is too low, they will be frozen, forming a hard core, which is not cooked or boiled; If the temperature is too high, it will sprout again, and it is best to control the room temperature at about 15. Sweet potatoes are damp and can easily cause germs to attack and cause rot, so it is best to store them in a breathable wooden box.
