Before entering the cellar to prepare for the sweet potato to enter the cellar, the old cellar hole will be dug again to meet the new soil. The old soil will be sent out of the cellar. If the pit is relatively dry, a few buckets of fresh water can be poured to keep the pits moist. Before storing sweet potatoes, use 50% carbendazim WP 1500 times, or 50% sulfur suspension 800 times evenly to spray the cellar, in order to achieve the purpose of sterilization.
Storage should be selected as possible pathogen-free bacteria, pest-free sweet potatoes, handling gently into the cellar, take care not to damage the sweet potato skin. About 150 kilograms of preserved sweet potatoes per store were sprayed evenly with the dilute solution of "fresh sweet potato preservative". Sweet potatoes are stacked by size to facilitate pouring. The height of the pile of sweet potatoes is about 60 centimeters from the top of the cave, so as to facilitate the cooling of the sweet potatoes.
