Then take a cardboard box, insert a few holes in the top of the box with a simple one, put the sweet potatoes in it, and then cover it with several layers of newspaper and put it in a cool place at a temperature of 13-16 degrees Celsius. In this way, it is not only ventilated and breathable, but also protected from light and dry, that is, sweet potatoes will not sprout and rot after half a year.

The second method: the sweet potatoes bought back are dried for half a day to evaporate the water on the surface of the sweet potatoes, so that they are not easy to germinate. Take a cardboard box, put a layer of sand at the bottom, then put a layer of sweet potatoes into it, and then put a layer of sand, after the sand has not passed the sweet potatoes, then place a layer of sweet potatoes, just like this, a layer of sand and a layer of sweet potatoes, and use sand to separate each sweet potato.

Then place the box in a cool, ventilated place with a temperature between 13-16 degrees.

1. Carton storage methodFind an empty carton, put a layer of paper towel on the bottom before putting the sweet potatoes to avoid moisture, then put the sweet potatoes in it, and then spread another layer of paper towels on top of the sweet potatoes after putting them, and finally seal them in a dry and ventilated place.

2. Newspaper wrapping methodWrap the sweet potatoes in newspaper one by one and pack them all in a bag.

3. Cellar preservation methodDig a cellar by hand and place the sweet potatoes in the cellar for preservation.

4. Sun-dried preservation methodSweet potato slices can be stored for a long time by drying them in the sun.

Precautions for storing sweet potatoesThe cellar of sweet potatoes should be selected in a place with high terrain, good ventilation, and no water seepage. The main thing is that the temperature is suitable, dry, humidity is suitable, etc. Ventilation and insulation, the air temperature is kept at 2-8 degrees.

Sweet potatoes should be stored in a ventilated and dry place.

Sweet potatoes are still sliding and respiring during storage after harvest. During storage, the ambient temperature is required to be 9 13, the humidity is controlled at about 85%, and there is sufficient oxygen. Storing sweet potatoes requires dry, cool, and low temperatures.

Sweet potato storage has corresponding requirements for ambient temperature, humidity and air composition: temperature 10 14, humidity 80 95%, oxygen and carbon dioxide in the air 15% and 5% respectively.

Sweet potatoes are stored as follows:

You can build a constant temperature library to preserve sweet potatoes, the constant temperature library has a unique system to adjust the temperature, only need to control the temperature, to ensure that the temperature of sweet potatoes in the storage process, constant between 10-14 degrees, not too low, at the same time to ensure that there is a certain amount of air circulation, to avoid the occurrence of lack of oxygen caused by sweet potato rot.

If there are fewer sweet potatoes, you can also use a cardboard box to save them, remove the soil on the surface of the sweet potatoes, be sure not to wash them with water, remove the soil, and then put the sweet potatoes neatly in the box, seal and store the box after putting it, and put it in a cool and dark place, this method is very practical.

Sweet potatoes

The fruit of sweet potatoes is the same as that of various sweet potatoes Morning glory, which is a round or flattened capsule with a diameter of between 5-7 mm, and the peel is dull green or purple when it is not ripe, and turns withered yellow or brown when ripe. Each capsule contains 1-4 yellow-brown or black seeds, about 3 mm in diameter. The size and shape of the seeds are related to the number of seeds in a capsule.

Generally, the one with one seed in a capsule is round, the one with two seeds is semicircular, and the one with more than three seeds is irregular triangle. It is most common to bear 2 seeds, and it is rare to have 4 seeds. The seed skin is thick and hard, not easy to absorb water, and it is difficult to germinate, so it is generally not used for production, but mostly used for breeding new varieties.

There are three common storage methods for sweet potatoes, namely cellar preservation, room temperature preservation, slicing and drying dry preservation, etc., and the most suitable temperature for preservation is between 13-16. Sweet potatoes are generally marketed around October, but due to the difference in planting time, there will be some differences in harvest time.

Sweet potatoes are generally marketed around October, not rented buckets due to the difference in planting time, so there will be a certain difference in the harvest time, if it is a storage of sweet potatoes must be harvested later, it is best to harvest before the frost.

There are three common storage methods for sweet potatoes, namely cellar preservation, room temperature preservation, slicing and drying preservation, etc., and the most suitable temperature for preservation is between 13-16.

1. Cellar preservation method

Friends who often grow sweet potatoes are no strangers to it, it is best to dig a 3-4 meters long, about 3 meters to submit, and then put the sweet potatoes in, cover them with a layer of plastic film, pay attention to leave a hole, do not seal too much, so that it can be stored for a long time.

2. Room temperature storage method

Storing sweet potatoes at room temperature is a very common method, suitable for the situation that sweet potatoes are relatively small, you can put a wooden board on the floor of the room, pay attention to control the temperature at about 15, the temperature is too high to germinate, the temperature is too low and easy to freeze, and the later pay attention to the envy type or wind of the environment.

3. Slice drying and preservation

This preservation method is more suitable for the case of not many sweet potatoes, specifically cutting the sweet potatoes into slices, and then drying them into dried sweet potatoes for preservation, so that they can be stored for a long time.

Summary. Dear, I'm glad to answer the first method for you: carton preservation method First of all, we have to select sweet potatoes, sweet potatoes will inevitably bump and bump in the process of harvesting and transportation, these bumps and broken skin of sweet potatoes do not affect the taste, but when preserving, we must pay attention to this kind of sweet potatoes with broken skin and black spots rotten must be picked out and eaten first, because such sweet potatoes are easy to spoil, and will pollute other sweet potatoes, affecting the storage time of sweet potatoes, don't let "a stinky fish ruin a pot of soup".

Dear, I'm glad to answer the first method for you: carton preservation method First of all, we have to choose sweet potatoes, sweet potatoes will inevitably have bumps and bumps in the process of harvesting and transportation, these bumps and broken skin of sweet potatoes are blind and do not affect the taste, but when preserving, you should pay attention to the red brother with potatoes with broken skin and black spots rotten in the empty plant must be picked out and eaten first, because such sweet potatoes are easy to perish, and will pollute other sweet potatoes, affecting the storage time of sweet potatoes, don't let "a stinky fish ruin a pot of soup".

Second, drying, after the sweet potato is selected, do not store it directly, but add one more step to dry, the purpose is to dry the moisture on its surface, so that the sweet potato is not easy to spoil and can be stored for a longer time. In addition, the dried sweet potatoes will be converted into sugar under the action of the enzyme of the lake, so the taste of the sweetened potatoes will be sweeter.

3. Packing, take a poor carton, first spread a layer of plastic paper at the bottom, and then spread a towel on it, and then put the sweet potatoes on the top of the towel one by one, leave a certain gap between the sweet potatoes and the sweet potatoes, do not take the empty shout crowded too full, and do not stack it to avoid injury, and finally fold the towel down to cover the sweet potatoes, seal the carton and put it in a cool place to preserve. Plastic paper has a moisture-proof effect, paper strips and towels have good moisture absorption, can keep the surface of sweet potatoes dry, sweet potatoes want to germinate, need to be temperature and temperature, conditions can not be reached, naturally sensitive will not germinate.

The second method: the first and second steps of the plastic bag protection and celebration cover storage method are the same as the first method, so I will not be verbose. 3. Wrap the dried sweet potatoes one by one with kitchen paper, and then put them in a plastic bag, drain the air in the plastic bag and then seal it tightly, and put it in a cool place to store it.

First: sweet potatoes must be stored in a dry environment, the temperature can not be too high, not too low, in a hot and humid environment, sweet potatoes are easy to germinate, cold and easy to freeze, so the environment must be dry, and when storing, do not touch the water, this is very critical. Second:

Try to choose an environment without light, that is, a darker place, the potato hole will not have light all year round, and the inside is completely out of sight, so if you want the sweet potato to be stored long enough, don't let it see the light. Third: there is flowing air, sweet potato preservation also needs a certain amount of air, it is the basis for sweet potatoes to be sweeter and sweeter, with circulating air, sweet potato segments are easier to preserve.

1) Indoor fresh storage method sweet potatoes are very afraid of cold, when the temperature is too low, it may be frozen, forming a hard heart, steamed and not cooked, boiled not rotten, such as the temperature is higher than 18 degrees Celsius for a long time, and will sprout. Therefore, it is best to keep the room temperature at around 15 degrees Celsius. At the same time, it is also necessary to pay attention to prevent the temperature from rising and falling.

Sweet potatoes are damp and can easily cause germs to attack and cause rot. Therefore, it is best to store it in a breathable wooden crate. If there is no wooden box, a wooden board should be placed on the place where the sweet potatoes are stacked and against the wall, and something should be covered on the potato pile to prevent it from getting wet.

In warm days, open the windows for ventilation to keep the indoor air fresh, but to prevent cold winds from blowing in. In addition, the best sweet potatoes on the market, due to shipment, some will be crushed and bruised, and the germs are easy to invade and cause rot. Therefore, it is best to leave the sweet potatoes in the sun for a few hours (do not leave them outside overnight) to reduce the moisture of the wound and promote healing, and when lifting, handle it gently to avoid bruising.

2) After steaming, dry and preserve, after steaming, cut each piece into three to four slices, and put them on the house 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, so be careful not to get exposed to the rain. After drying, store it indoors in a dry place.

Wash with water before eating and steam.
