How to store vegetables in the cellar in winter, such as coriander, cucumber, purple cabbage, etc.,

1. Because the temperature of the underground cellar in winter is generally higher than that of the ground surface, it can effectively prevent frostbite in winter. , usually in winter parts of the north prefer to use cellars to store cabbage.

2. Because the closed cellar provides a low temperature and low oxygen environment, the carbon dioxide concentration increases, which will inhibit cellular respiration, thereby prolonging the fresh time of fruits.

The cellar is warm in winter and cool in summer, and the Chinese cabbage is stored almost at a constant temperature, so it is as fresh as ever, neither frozen nor too hot to rot.

In the vast northern region of our country, especially in the northeast region, farmers generally use cellars to store vegetables in winter, so that the stored vegetables are generally relatively fresh to meet the needs of a family in winter.

So what is the principle of the cellar, in fact, the reason why the cellar can store vegetables is because the temperature in the ground is generally higher than the surface of the ground in winter. This is caused by the slow transfer of heat from the land, in the hottest time of summer, the surface temperature is very high, and about 1 meter underground is the second highest, gradually lower and lower temperature, and each height of the underground ushered in the moment of high temperature is not the same, the highest temperature on the ground should be July, 1 meter underground is August, and about 3 meters is September. When a certain depth is reached, the temperature of the ground remains the same.

The principle of winter is the same, because the land is slower to transfer cold, so when it reaches a certain depth, the temperature can be kept at a higher level. So people in the north can take the cellar to store vegetables.

Without oxygen the temperature is also high.

In winter, the northern cellars are mainly stocked with cabbage, potatoes, green radish, carrots, carrots. With the improvement of living standards, fruits such as apples, oranges and other fruits are now stored.

The cellar maintains the temperature, regulates the temperature.

It manifests itself in two ways.

1. Due to the large specific heat capacity of water, a certain quality of water rises (or decreases) a certain temperature to absorb (or release) more heat, which is conducive to using water as a coolant or keeping warm. The former is to let the water absorb and take away more heat; The latter is to let out more heat from the water.

2. Due to the large specific heat capacity of water, a certain mass of water absorbs (or releases) more heat while its own temperature does not change much, which is conducive to regulating temperature.

1.How to store winter vegetables: The most important thing to preserve leafy vegetables in winter is to retain water and avoid leaf rot.

2.The easiest way is to use old newspapers, spray some water on the leaves, and then wrap them in newspaper and put them in the refrigerator with the roots facing down, which can effectively extend the storage time and retain the freshness.

3.If you can't eat the leeks, garlic and other green vegetables purchased in winter, you can wrap them in fresh Chinese cabbage leaves and put them in a cool place to keep them fresh for several days.

4.The lettuce will gradually soften and change color after a while, you can remove the cabbage sum, then stuff a moist paper towel into the cabbage sum to let the lettuce absorb the water, wait until the paper towel is dry, and then put the lettuce in a plastic bag to refrigerate.

5.Shiitake mushrooms, straw mushrooms and other mushroom vegetables, after buying home should be kept dry as much as possible, put in a plastic bag and then refrigerated for about 4 5 days, fresh vegetables are not durable, it is best to cook immediately to maintain umami and color.

6.White radish, onions, etc. can be left for a long time, as long as they are placed in a cool place.

7.Tomatoes can be placed one by one on the windowsill, facing down.

8.In the case of celery, you can wrap the part of the rod with a newspaper and tie it with a rope, so that the root is about an inch long.

9.Then put it in the water standing upright, don't let the newspaper get wet, you can leave it for a few days.

It can be stored in the cellar in one piece.

First, the basic structure of the cellar:

Both in the south and in the north, the cellar serves the function of preserving vegetables and sweet potatoes in winter.

However, the storage cellar is scientific, first of all, the depth of the cellar is generally required to be less than 2 meters, or even reach a depth of 10 meters, such a depth, in the north has exceeded the thickness of the permafrost, the contents of the cellar will not be damaged by frost and rot and deteriorate.

Second, the method of storage:

When storing, it is necessary to dry the cabbage properly, eliminate the surface moisture as much as possible, and then stack it in layers in the cellar, do not pile it, because the water content of the cabbage is high, and together it will be exothermic because of their breathing, causing the vegetable balls to rot and deteriorate. It is best to have a shelf made of stainless steel or plastic steel, so that the cabbage can be evenly breathed and the air is relatively easy to circulate.

The stacking of sweet potatoes can be placed in bags, the best sacks, the small kind, a bag of 20 catties, can be stacked three or four layers, before entering the cellar, the sweet potatoes should be dried to eliminate surface moisture, and the sugar content of sweet potatoes can also be improved.

Cabbage and sweet potatoes should be stored separately, not piled together, the water of the cabbage will run down, and the whole cellar will be filled with dampness.

Three: management after storage:

The cellar requires a ventilation opening, which is open in sunny and hot weather (in winter) and replaced with fresh air into the cellar, so that the carbon dioxide inside can be exchanged, and there is no need to worry about the carbon dioxide sinking under the cellar, because the air temperature inside is high and will rise, while the temperature of the ground is low, it will be the fresh air sinking.

Fourth, precautions;

Before entering the cellar, it is necessary to open the vents for ventilation, because there is a high probability that there are toxic gases in the cellar, because cabbage and other items will be stored in the cellar due to the toxins produced by individual spoilage. So be careful.

Yes, it can play a role in keeping fresh and preserving.

It must be, mainly cold-proof.

Sweet potatoes can be cabbage can't.
