西瓜季节性强,上市集中(约一个月左右),容易造成损耗。1979年我们用速冻、冷藏、人防洞(或山洞)贮藏西瓜,结果如下:速冻:西瓜放入-30℃冷库后,很快冻结。虽然贮藏时间可以很长,2～3年都不会坏。但出库后由于外界温度高,西瓜很快融化,瓜瓤软,食之味淡,出库后要很快吃掉,否则要坏。 Seasonal strong watermelon, the market concentrated (about a month or so), easily lead to loss. In 1979, we used quick-frozen, cold-preserved and civil air-defense holes (or caves) to store watermelons. The results are as follows: Frozen: Watermelons freeze quickly after they have been placed in a freezer at -30 ℃. Although the storage time can be very long, 2 to 3 years will not be bad. However, due to the high temperature outside the library, the watermelon melts quickly, melon is soft, the taste of food is light, and the food should be eaten quickly after the delivery, otherwise it will be bad.
