It is said that the rural elderly like to use the grain stored in the cellar. What are the benefits of cellar storage?

The main characteristics of the cellar should be suitable temperature, dryness, convenience for food storage and the function of refrigerator. I remember when I was a child, in the mountainous area, every family would dig several holes on the hillside behind the house, either to store potatoes and cabbage or to store sweet potatoes. The area of the storage room can be determined according to the number of items stored. After the sweet potato is put away, cover the pit and open the lid at any time according to the temperature change. The temperature should not be too high, otherwise it will be easily damaged and rotted.

Why dig a cellar for storage? This is because there are too many vegetables to store. Enough for the whole family to eat for a winter. Not a few kilograms. You can find a corner in the house and pile them up. That's hundreds of thousands of pounds. There must be enough spacious space. The cellar is warm in winter and cool in summer. This is a good place to store food and vegetables. In my local hometown, storing potatoes and cabbage is also a very common storage method. Storing potatoes and cabbage in the cellar can keep you warm.

The walls around the food cellar are vertical. After the pit is dug successfully, we will put some wooden purlins on the top of the pit, then shed the pit door with corn straw, spread a layer of grass on the straw to prevent leakage, and then step on the soil beach. There is less oxygen in the cellar. Of course, when the cellar was first dug, it was the same as outdoor. When we store sweet potatoes and potatoes in them, they will have aerobic respiration. Because of the tightness of the cellar, they will gradually become anaerobic to breathe.

We should also pay attention to the safe use of cellars, especially deep cellars. If no one goes down for a long time, it may be dangerous because of lack of oxygen. Farmer friends must pay attention to this. The cellar is relatively low and dry, and the density of carbon dioxide in the air is lower than that in the air. Finally, most of the carbon dioxide is deposited in the cellar, which will also lead to a high concentration of carbon dioxide in the cellar. Therefore, there are many tragic lessons to be learned before entering a long-term unventilated cellar. If there is no oxygen in it, people can't get up if they go down. We all wait for ventilation, light candles in the basket and put them at the bottom of the cellar! If the candle is still on, go to the basement!
