First, fresh ginger can not be put together with Chinese cabbage, spinach, leeks and other leafy vegetables. Because the suitable temperature for storage of the above leaf vegetables is 0 to 2°C, it can cause "hot injury" and mildew when the temperature exceeds 4°C. The fresh ginger storage temperature is 12 ~ 13 °C, below 10 °C will be frost damage and deterioration, above 15 °C will sprout. Second, potatoes and sweet potatoes cannot be stored in the pit. Because the sweet potato is warm, the minimum temperature for storage is 15°C, and the temperature is too low to be susceptible to freezing and rot. The potato likes cool, the best storage temperature is 2 ~ 4 °C, the high temperature will germinate and turn green, producing toxic substances.
