How to store sweet potatoes at home in winter

In winter, sweet potatoes are stored at home and neatly placed in the cellar. Finally, sprinkle some preservatives and cover the cellar with haystacks.

After the temperature rises in spring, in calm and sunny weather, when the temperature exceeds 65438 02℃ at noon, the concentration of miscellaneous bacteria in the cellar can be reduced, and the mildew on the damaged skin of potato pieces can be prevented from being caused by excessive humidity in the cellar.

Especially in potato pits with poor thermal insulation performance, we must not be careless. Once the cellar temperature drops, immediately cover the vent for thermal insulation, and use heating facilities for proper heating if necessary. When the humidity in the cellar is low, water should be added to the cellar or wet grass curtains should be laid on the walkway to increase the air humidity in the cellar.

Extended data:

growing period

The growth period of spring potato is 160-200 days, and that of summer potato is about 1 10- 120 days. According to the growth characteristics of Chiquan in the wild and its relationship with climate conditions, it can be roughly divided into three growth periods:

1, prophase: 60-70 days for spring potato and 40 days for summer potato. At this stage, the stems and leaves grow slowly and the roots develop rapidly, mainly in the period of long fiber roots.

2. Mid-term: 50 days for spring potato and 30 days for summer potato. At this stage, the root tuber expands slowly, and the stems and leaves grow rapidly, which is a period of mainly growing stems and leaves.

3. Late stage: spring potato is after late August, and summer potato is after early September. This period is the main period of root enlargement.
