减少马铃薯在长期贮藏下的损失对增加这个有价值的产品的资源是有很大意义的。这种损失的主要原因之一是和马铃薯解除休眠状态有密切关系的块茎发芽。在春夏贮藏期出芽的重量达到块茎重量的10—15％。由於马铃薯发芽,失去了大量贮备的营养特质和水分,降低了块茎的重量,使块茎变萎缩。在发芽的马铃薯块茎中积累了一种配醣体——增加马铃薯不正常的味道和对人畜都有极大毒害的龙葵精。在发芽的块茎中大大地减少了维他命C的含量。为了抑制马铃薯块茎的发芽,在冬末期间置马铃薯于冷冻土壤的贮藏壕内,在冷冻的壕内使其受到低温的影响。但完全採用这种方法是较困难的, Reducing the loss of potatoes under long-term storage is of great importance to increasing the resources of this valuable product. One of the major causes of this loss is the tuber germination, which is closely related to the dormancy of potato. In spring and summer, the weight of budding reaches 10-15% of tuber’s weight. As the potato sprouts, the loss of a large number of stored nutrients and water, reducing the weight of tubers, tubers shriveled. In the sprouted potato tubers have accumulated a glycoside - to increase the potato’s unusual taste and have great toxicity to humans and animals solanine. The vitamin C content is greatly reduced in the germinated tubers. In order to inhibit the germination of potato tubers, potatoes are placed in the frozen soil storage trenches during the late winter and are subjected to cryogenic temperatures in the frozen trenches. However, it is more difficult to adopt this method completely.
