甘薯(山芋)高温大屋窖,是甘薯安全贮藏的“保险库”。我县自1974年开始建窖至1979年以来,已发展到3,099个,基本上实现了山芋窖藏高温愈合大屋化。种薯坏烂率由原来的27％压低到1.6％。但因高温愈合大屋窖为单道烟道,烧时较费煤,又因单道烟道长度较短,火苗极易通过烟筒伸出屋顶,稍有疏忽,容易发生火灾。为了提高愈合防病效果及节煤和安全起见,1977年,我们对山芋高温愈合大屋窖的烟道进行了改造革新。在不减少仓贮量的前提下,将原来的单道烟道改造成“品字”型三道烟道。具体做法是:两道烟
Sweet potato (potato) high temperature large house, is safe storage of sweet potato “vault.” Since 1949, the county started to build cellars to 3,099 since 1979, basically realizing the high-temperature healing of the potato cellars. Broken down the rate of seed from the original 27% down to 1.6%. However, due to the high temperature healing large house as a single flue, burning more coal, and because of the length of a single channel flue, the flame easily extended through the chimney roof, a slight negligence, prone to fire. In 1977, in order to improve healing and disease prevention and save coal and safety, we made innovations and innovations on the flue-cured tobacco in a large house with high temperature. Without reducing the storage capacity of the premise, the original single-channel flue into “character” type three flue. The specific approach is: two cigarettes
