Embodiment Construction

[0012] 1. Harvest in good time to avoid mechanical damage. Summer potatoes should be harvested before and after frost, and autumn potatoes should be harvested before the beginning of winter. Harvest on sunny days, and minimize or avoid wounds when digging potatoes.

[0013] 2. Choose healthy potatoes to ensure safe entry into the cellar. Before the sweet potatoes enter the cellar, they should be carefully selected, diseased, incomplete, and rotten potatoes should be eliminated, and the moisture should be dried before entering the cellar, and new cellars should be used as much as possible. Before the old cellar is used, the old soil in the cellar should be removed to expose the new soil, and 15 grams of sulfur per square meter can also be used for fumigation and disinfection.

[0014] 3. In the early stage of storage, that is, within 30 days after entering the cellar, the main work during this period is ventilation, heat preservation and moisture dissipation. The temperature i...
