Potatoes are very easy to germinate during storage. Once they germinate, they can't be eaten because they will cause poisoning. So how do we preserve potatoes? Let's take a look.
How can potatoes not germinate
1. No exposure to the sun
We must carefully select potatoes before preservation, which have been green, rotten potatoes are all removed, if not removed, other potatoes will also deteriorate. And put it into the bag, put it in a cool and ventilated place, must avoid sunlight, in order to avoid its photosynthesis.
2. Don't get wet
Potatoes can not be stored in a humid environment, it is easy to cause mold, storage place best can absorb its excess water, such as sand.
3. No high temperature
If the temperature of potato storage is too high, then the potato will rot and germinate, leading to inedibility. So be sure to store it in a cool and ventilated place.
4. You can't live together
Potatoes should not be placed together with other vegetables. It's better to store them separately.
5. Avoid sweet potatoes
Potatoes and sweet potatoes can not be stacked together, if the two are together, potatoes will germinate, sweet potatoes become hollow.
How to keep potatoes green
1. Preparation before warehousing
First of all, we should prepare a warehouse with enough storage, which should be well ventilated and not too wet. The temperature should not be too high, its wall should be lime water, because it can absorb the excess water of potato, so it can be better preserved.
2. Stacking
The storage period of potatoes is very short, so when stacking, the height should not exceed 1 meter. At the same time, the warehouse should not be full, and one third of the space should be reserved, because potatoes need ventilation.
3. Temperature and humidity control
The temperature of the newly unearthed potatoes is between 15 ℃ and 20 ℃, so we need to wait about 15 days to store them. It will cool down every day, when its temperature is maintained at about 2 ℃ - 3 ℃, it can be stored, and the humidity of the warehouse should be maintained at 80%, which is the most suitable temperature and humidity for storage.
4. Illumination
Where potatoes are stored, the requirements for light are very high, because when potatoes are exposed to sunlight, photosynthesis will occur, which will promote potato germination.
