地瓜是我县主要粮食作物之一,常年种植面积四十余万亩,产量占粮食总产量的一半左右。过去每年贮藏地瓜种四、五千万斤,但由于窖型、管理不科学,历年损失二干多万斤。一九六八年通过学习外地大屋窖高温处理贮藏地瓜种的经验,全县先后建造大屋窖七百五十六个、二千八百六十间。基本上做到了安全贮藏。去年全县贮藏瓜种八千 Sweet potatoes are one of the main grain crops in our county. The perennial planting area is more than 400,000 mu, accounting for about half of the total grain output. In the past, four or 50 million jin of sweet potatoes were stored each year. However, due to the cellar type and unscientific management, over 20,000 jin of losses were lost over the years. In 1968, through studying the experience of high-temperature storage of sweet potatoes in the large house cellars in the field, the county built a total of 756 large chambers and 2,860 large chambers. Basically done safe storage. Last year, the county stored 8,000 melons
