There are a lot of sweet potatoes harvested in the field, how can they be better stored?

It's already October, and the sweet potato harvest season is coming soon. For autumn sweet potatoes, the sweet potatoes we grow are harvested during the late October time period. In particular, it is necessary to harvest before frost so that sweet potatoes are not destroyed by early frost.

According to many farmers this year, the drought was severe in the second half of this year, and the water shortage of sweet potatoes in the later period was frequent. So this year, the overall size of sweet potatoes is not expected to be as high as in previous years, but because of the lack of moisture, the sweetness is much better. So how can we preserve the sweet potatoes after we harvest them to last longer?

The first method: basement, save the basement. This is the most common way to preserve sweet potatoes.

Because the basement can be preserved to maintain a stable temperature and humidity, the general temperature is between 12 14 and the humidity is between 80 and 85%, which can well preserve sweet potatoes and ensure the freshness and taste of sweet potatoes. Generally speaking, when we choose a basement, we should choose a well-ventilated sheep land, a relatively high area, and a place where water leakage will not occur. After the sweet potatoes are stored at the same time, they should be sealed well to prevent the cold wind from entering the frozen sweet potatoes in winter.

The second method: the farm is dry, ventilated and dried. In our southern region, the harvested sweet potatoes are often placed on the floor of a wood-burning firewood house.

This sweet potato is often smoked and stays dry for a long time, and this is a place where rats rarely come to find it.

Sweet potatoes have less moisture after drying for a while and are easy to preserve. This method is more common in many rural areas, so you can try it if the conditions are right. The third method:

Sweet potato slices are stored dry. In this way, the sweet potatoes can be stored for a longer time, and the sweet potatoes are basically dry in water and will not become moldy in the spring. At first, wash the slices and let them dry, and finally store them in a ventilated and dry place.

Second, some farmers make sweet potatoes into sweet potato flour and seal them with plastic wrap. This way is also better, but it is not suitable for the case of large quantities of sweet potatoes. If you have a large amount of fresh sweet potatoes and don't want to dry them directly, it is best to store them in a basement or well storage vault with a seal.

The main methods of sweet potato storage include cellars, well cellars, indoor storage, and slice storage. After harvesting, it is best to dry the sweet potatoes for a period of time to remove part of the moisture on the surface, so as to avoid excessive moisture due to excessive respiration during the direct cellaring process, which will produce moisture and make the air humidity in the cellar too large. The sun is not easy to be too long, and it is best to cover it with a plastic sheet at night to avoid being wet by dew.

In fact, the storage method of the cellar and the well cellar are similar, and they both need to dig out a certain depth of space, but the depth and size are not the same.

Try to put it in a cool and confined space, this is how it used to be stored at home, and this way can be stored for a very long time.

Store in the cellar. The cellar is a dry environment, especially suitable for crops like sweet potatoes, which can be maintained for a long time.

I think you can dig a cellar to store them, and these sweet potatoes will generally not go bad when stored in the cellar for half a year.

Sweet potato vermicelli is a good thing, eat hot pot in winter that is indispensable to it, sweet potato vermicelli is not only smooth, but also very nutritious, we all know, sweet potato is recognized as anti-aging, anti-intestinal cancer food, it is not only nutritious, the injured or a little bruised sweet potato picked out and thrown away, don't be reluctant, because if we don't pick it out, put it together with good sweet potatoes, it will cause other sweet potatoes to be infected, resulting in good sweet potatoes bad.

When storing, you can soak or spray evenly with an appropriate sweet potato preservative solution, and after the solution is fully absorbed and dried, use a cardboard box or wooden box, straw, etc., or sand, pay attention to keep warm, prevent frostbite and excessive temperature, pay attention to moisturizing, and if possible, it is recommended to cellar.

<> sweet potato for storage conditions are more stringent, sweet potato storage temperature can not be too high, can not be too low, too high or too low temperature will cause a certain degree of damage to sweet potatoes, the general temperature of 10 degrees to 14 degrees is appropriate, if there is no cellar, we can spread a layer of straw or wheat bran in the house, spread a layer of plastic paper on top, and then spread a layer of straw, select healthy and disease-free, damaged sweet potatoes, gently pile up the sweet potatoes, surrounded by straw felt or reed mats, That is, it can stay fresh for several months. The storage method in the cellar is to keep the moisture inside the sweet potatoes and maintain the quality of the sweet potatoes. So if we don't have a cellar, we have to make or find another environment like this for storage.

Use a large wooden barrel, the barrel is best placed in a place where there is no wind at home, spread a layer of straw underneath, and then put the dried sweet potatoes layer by layer, put a layer of straw, and keep it full until it is full. The optimal temperature for storing sweet potatoes is 11 to 13 degrees, below 11 degrees may cause frost damage, and above 13 degrees, there will be rotting, so temperature control must be strictly monitored. Dig a pit with a depth of 80 meters in the sand, put the sweet potatoes in a layer of plastic film, and cover them with a thick layer of sand.

We should put the sweet potatoes in some cooler places, so that the sweet potatoes will not spoil, and the sweet potatoes can be stored well.

Sweet potatoes must be kept in a dry environment, the temperature should not be too high or too low, because the temperature is too high and sweet potatoes are easy to germinate, and if the weather is too cold, it is easy to freeze. Therefore, it will be stored longer in a dark environment without light.

Sweet potatoes like temperature and fear of cold and damp, need to store the appropriate temperature 10 14, the optimal humidity for sweet potato storage is 80%-95%, sweet potato cellar capacity can not exceed 2 3, leave space, in order to facilitate ventilation to remove moisture, to prevent "stuffy cellar".

It can be stored in the cellar, be sure to pay attention to the temperature, and do not store it in a particularly cold or warm place.

The best thing to do is to store the sweet potatoes in the cellar, so that the sweet potatoes will not go bad for half a year.

Sweet potato is a very common food in China, because it contains a lot of nutrients, and it is easier to plant than rice and wheat, so sweet potatoes are planted in many places in China, but some places or some people plant red yields are very high, but some people plant sweet potatoes in yield and quality are relatively low, so how to plant sweet potatoes to be able to produce high-yield sweet potatoes, and how to store them after harvesting? <>

First of all, the sweet potato planting is not just a difference, but according to the growth of the sweet potato in a timely manner to replenish the seedlings, at the same time in the process of the growth of the sweet potato to weed, in the sweet potato growth to a certain time, generally two to three months after the sweet potato planting weather conditions will be very changeable, at this time we must pay attention to the sweet potato planting place drought prevention or drainage. At this time, you can root the sweet potato, but do not turn it. Each acre of sweet potato can also be sprayed with a certain amount of chemical fertilizer to control the prosperity, and at the same time, it is also necessary to pay attention to the fertilization of sweet potatoes, and the specific method is to use plant ash or potassium sulfate fertilizer for sowing.

Secondly, after the sweet potato is harvested, we must pay attention to storage, if the storage is not good, the sweet potato will easily become trapped and mildew. When storing sweet potatoes, be sure to carefully screen them, and it is best to store those that have just been harvested from the land, free of pests and diseases, and free of scars and breakage. It will be easier to store the sweet potatoes that have been received after the June Sun searches, and if the sweet potatoes have been wounded or have insect eyes, they cannot be stored at once, and these sweet potatoes can be used as staple food or for livestock.

This can avoid the rotting of the stored sweet potatoes, and also allow Wang Kai or really good sweet potatoes to get enough space to store them, so as not to waste space. <>

Finally, be sure to choose a place to store sweet potatoes. Before storing sweet potatoes, be sure to choose an environment with very suitable temperature and humidity, and choose a ventilated place. After the sweet potatoes have been stored, it is important not to carry them a second time, as this can easily lead to trauma to the sweet potatoes.

If the water content of the cellar where the sweet potatoes are located is relatively high, it should be cooled and drained, so that the cellar is in a ventilated environment, if the sweet potatoes have been soaked in water for a long time, they cannot be stored in the cellar, and it is better to feed pigs or make mills.

You can choose deep ploughing, properly loosen the soil, ensure the permeability of the soil, and properly carry out high ridge dense planting. Be sure to store it in a cellar, in a dry and cool place, and try not to have epidermal trauma.

When planting sweet potatoes, you can first carry out excitation and plough cultivation on the soil, and then ensure that the soil is planted without any problems, and also water and fertilize the red potatoes in time. It can be stored in the cellar, after all, the cellar environment is cooler and more suitable for storage.

It is necessary to choose the right varieties for planting, you need to pay attention to watering, pay attention to fertilization, and you can choose to store them in the cellar during the harvest.

Winter sweet potato storage has a higher temperature and humidity in the storage space. Because the temperature of sweet potatoes should not be too high or too low during storage, and the air humidity should also be well controlled. Sweet potatoes are easy to germinate when the temperature is too high, and sweet potatoes are easy to suffer from frost damage when the temperature is too low, especially when it is lower than 10, which affects the taste, that is, it is not boiled, steamed and hard; Severe frost damage will cause rotting, water and so on.

The humidity of the storage space should also be controlled, especially when the sweet potato is just stored, the respiration is relatively strong, and it is easy to produce a lot of water vapor, resulting in excessive humidity, and the humidity is too high to breed pathogens, so that the sweet potato has soft rot and nematode disease. In addition, when storing sweet potatoes, it is also required that the sweet potato tubers should not have disease spots, damage, and insect eyes. After clarifying the conditions for sweet potato storage, it is time to formulate a method for sweet potato storage.

In addition to cellaring, growers with conditions can build a constant temperature storage warehouse, and determine the area of the storage warehouse according to the planting area. The most important thing is that the storage warehouse should be able to control the indoor temperature and humidity, if you want to lower the cost, you can build insulation facilities around the storage, such as fire tunnels, etc., when the temperature is low in winter, it can be automatically heated, and it should be convenient for ventilation, ventilation and cooling when the temperature is high.

Smaller planting areas can be stored indoors. Straw and straw can be laid indoors to keep warm, and sweet potatoes should not be placed directly on the floor, but should be laid with wooden planks on the ground and against the wall. Before storing sweet potatoes, ventilate the room to reduce indoor air humidity.

When the temperature is low, seal and insulate, and ventilate and cool down when the temperature is high. You can also put sweet potatoes directly in a wooden box, put straw or straw in the wooden box, and seal it with small holes for ventilation. Place the wooden box indoors.

There are two key points in the preservation and storage of sweet potatoes, one is to ensure that the treatment before storage is done to ensure that the sweet potatoes are healthy, and the second is to store them appropriately according to their own conditions. Treatment of sweet potatoes before storage: After harvesting, sweet potatoes should be kept in the case of sufficient ventilation at a temperature of about 30 degrees and humidity of about 93%, and put them for 4 6 days.

Sweet potatoes, before entering the sugar cellar must not be too high, so as not to accelerate its decay, if more than 70%, then you should open the vent first, drain the moisture, for those sweet potatoes with too much water content, it is recommended to use as soon as possible, not suitable for storage.

Choose the right storage method: the storage method of sweet potatoes generally has three kinds of cellars, shed cellars and cellars, the well cellar should choose a relatively high terrain, the land is relatively strong, and the underground water level is relatively low, maintain the dry environment of the entire well cellar, dig down a diameter of about one meter and the depth of field is 5 6 meters, and the storage room should be padded with some dry sand and then put on the sweet potato, and the sweet potatoes can not be stacked too full, about 7 into it, to leave them room for ventilation. Shed storage generally dig a cellar of about 6 8 square meters to gradually pile up sweet potatoes from the bottom up, where direct contact between sweet potatoes and the wall should be avoided, and the breathing space should be avoided.

The third is cellar storage, the cellar is placed in the house, but the house used for storage is better sealed, and the walls are thicker than ordinary houses, and the cellar storage is more convenient and fast, suitable for farmers to store.

Is it measured by the ton? Rent a freezer and dig a cellar.

It is not difficult to buy too many sweet potatoes and store them, this method is very simple and it will not be bad to store them for a year!

1. Sweet potatoes are stored in the well cellar

Choose a place with high terrain, solid soil and low groundwater level, and dig a wellbore downward, generally about 1 meter in diameter and 5 6 meters deep in the wellbore. The size of the storage room can be determined according to the amount of storage. In the storage room, 10-15 cm thick dry sand should be padded, on which sweet potatoes are placed.

Sweet potatoes can only be filled to 70% in order to leave room for ventilation, otherwise they will rot aggravated by humidity and heat.

2. Sweet potatoes are stored in the shed

Generally, dig a cellar about 2 meters wide, 3 4 meters long, and about 2 meters deep. Stack the sweet potatoes from the bottom up one by one, and avoid direct contact between the sweet potatoes and the cellar wall.

3. Sweet potatoes are stored in the cellar

The structure of the cellar is similar to that of ordinary houses, but the walls and roof are thick, sealed on all sides, the windows are open, and there are fire channels for heating, which can be treated with high temperature callus. There are two types of cellars: large cellars (storage of 15,000 kilograms) and cottage cellars.
