Sweet potatoes often go rotten during storage, causing great losses. The main reasons for causing rotten pits are: 1. Delayed collection and damage to potato peels. Sweet potato is a kind of warm crop that stops growing at below 14°C. If a large number of cuts or bruises occur during harvest, it will open the door for the invasion of germs. Such sweet potatoes will easily rot after entering the pit. 2, the poor condition of the potato cellar insulation. If the sweet potato pit is dug too shallowly, or if it is too late to cover the pit after entering the pit, or if the pit is too large to store too little sweet potato, or if it is opened in the winter season, the heat in the pit cannot be maintained, and the sweet potato is repeatedly affected by low temperature. 3, closed cellar is not enough ventilation. In the early period of sweet potato entry, sweet potato does not enter dormancy, and the respiration is vigorous, and the temperature and humidity rapidly rise. If the cellar is too early or there is insufficient ventilation in the open cellar, it will cause high temperature and humidity in the cellar. This soft rot easily occurs. . 4, the old cellar repair, disinfection is not good. For the old potato pit where sweet potatoes have been stored and rotten through the pits, there are a lot of germs in the pits. Once the temperature in the pit is lower than 9°C and the humidity is 95%, the germ quickly invades the potato block and causes a loss of "rotten pits." The main methods to prevent the storage of rotten potatoes are: 1. Harvest in time to reduce damage. 2. Strict old cellar disinfection. Before entering the cellar, the old soil around the cellar shall be cleared out, then burned with firewood for about 15 minutes, and then disinfected with potassium permanganate or a disinfectant, and then sprinkled on the bottom of the cellar with fresh lime and lime. Lay a layer of sand and layer the sweet potatoes. 3. Close the cellar in due course, pay attention to ventilation and heat preservation. Within 15 to 20 days after entering the cellar, the cellar may not be sealed, and the temperature may be maintained at 15 to 16° C. and the humidity may be 80% to 90%. During this time, it is necessary to pay attention to ventilation. Afterwards for the storage period, the temperature is preferably controlled at 13 to 15°C. Do not open the cellar often after sealing the cellar in winter, and prevent rain and snow from entering the cellar.
