heat proof. The suitable temperature for the preservation of sweet potato is 10 °C ~ 15 °C, the most ideal of which is 12 °C ~ 14 °C, reached 15 °C ~ 20 °C, the potato block will germinate, rot. Within 15 to 30 days after the sweet potato has entered the pit, the potato block is vigorously breathing, emitting a lot of heat, and there is water vapor and carbon dioxide, which can easily increase the temperature in the pit. At this time, management should be based on ventilation and heat dissipation. In addition, after the early spring temperatures have risen, it is necessary to promptly ventilate and ventilate the potato pits. Frost protection. When the temperature of the potato block is lower than 10°C, it will cause frost damage, resulting in atrophy of the potato block, hardening of the potato core, and black ribs under the cortex. Seriously, there will be a "rotten pit." The method of preventing freezing damage: First of all, it is impossible to let the frozen potato pieces enter the pit; secondly, in the winter snow days, the pits must be covered and the ventilation holes must be blocked. In indoor or outdoor potato piles, cover straw or other soft grass early. If the weather is too cold or there is snow, be sure to cover the plastic film, not only to maintain the temperature of the potato but also to prevent the snow from leaching into the potato heap. Prevent disease. Potato chips with scars and diseases are not allowed to enter the pit. First of all, we must do a good job of disinfecting before storage: Use a shovel to cut off the soil of every year on the four walls of the well pit, then spray it with 500 times the carbendazim solution. Before storing the fresh potatoes in the pit, use 1000 times of carbendazim or sweet potato preservative, put them into the soak, and then remove them and put them into the pit.
