The reasons for sweet potato rot are nothing more than three, one is that there is trauma, the second is when the rain is late in the planting period or when it is rained during storage, and the third is the infection with bacteria. For the above three factors, it can be prevented from the following aspects: During the early storage, that is, within 30 days after entering the pit, the main work during this time is ventilation, heat preservation and loosening, the temperature is controlled below 15°C, and the humidity is controlled at 90°C. %-95%, use ventilation holes, doors, windows or exhaust fans to enhance ventilation. If the temperature is high during the day, the method of opening the cellar door at night and closing it during the day may be adopted. Since the temperature gradually decreases, the vent hole can be closed overnight. When the cellar temperature is stable below 15° C., the cell door can be no longer ventilated. In the middle period of storage, that is, the period from the early period to the beginning of spring, the temperature of the cellar is reduced, which is the period when the potato block is most vulnerable to cold damage. Insulation and cold-proofing is the focus of work, and the cellar temperature should not be lower than 10°C, preferably controlled at 12°C-14. °C. Close the ventilation holes or doors and windows, thicken the outer insulation layer of the pit, and cover the straw mat or soft grass on the potato heap. After the storage period, that is, after the spring (March), the outside temperature gradually increases, and the cellar temperature must be checked frequently and kept at 10°C-14°C. The high temperature at noon must promptly release the air, and the air outlet should be closed in the evening to keep the cellar temperature within the suitable range. within.
