用塑料薄膜苫盖甜菜堆，可有效保藏甜菜。在保藏过程中，堆外温度变化很大、下降到很低时，堆内温度比较稳定。甜菜在保藏中重量下降，块根锤度、含糖率、还原糖有所上升，堆表面甜菜重量减少比堆内多，堆内甜菜还原糖、锤度、含糖比堆表面甜菜上升幅度大。
Cover the beet with a plastic film and save the beets effectively. During the deposit process, the temperature outside the reactor varied greatly. When the temperature dropped to a very low level, the temperature inside the reactor was relatively stable. The weight of beet decreased during the storage, the brix, the sugar content and the reducing sugar increased. The weight of beet on pile surface decreased more than that on the pile, the reducing sugar, brix and sugar content of sugar beet pile surface increased greatly.
