1. How to store purple sweet potatoes for a long time?

1. The high-temperature storage method is to burn a fire after the purple sweet potatoes are put into the cellar and raise the temperature to 35-38°C, and keep it for 2-3 days to kill pathogens such as black spot disease and soft rot on the purple sweet potatoes. Then lower the temperature to 10-14°C for low-temperature storage.

2. Use the low-temperature storage method. After the purple sweet potatoes are harvested, they should be handled promptly and put into the cellar promptly. After the purple sweet potatoes are put into the cellar, use various methods to keep the temperature in the cellar below 15°C and above 10°C. A cellar temperature below 15°C can inhibit the activity of pathogens, and a temperature above 10°C can avoid frost damage, achieving the purpose of safe storage.

3. Strengthen the management of the sweet potato cellar during the storage period. From putting sweet potatoes into the cellar before the Start of Winter to taking them out after the beginning of spring the next year, it can be divided into three management periods: the early winter period, the overwintering period, and after the Start of Spring. In the early winter period (before Major Snow), the temperature in the cellar is relatively high and the humidity is high, so the focus is on cooling and removing moisture.
