利用冬季机械通风降低粮温,再采用长期密闭不撤膜的办法,通过试验发现采用该方法保管储粮,符合一般储粮规律、粮情稳定、无结露升顶等现象,储粮色泽气味正常,储粮在塑料薄膜压盖长期密闭状态下安全度过全年,达到了节省人力、节约费用、延长塑料薄膜使用寿命的目的。 The use of winter mechanical ventilation to reduce the grain temperature, and then use the long-term airtight uncapped membrane method, the test found that the method used to store grain storage, in line with the general principle of grain storage, grain stable, no condensation top and other phenomena, stored grain color odor Normal, stored grain in the long-term confinement of plastic film gland state of the safety throughout the year, reaching the purpose of saving manpower, saving costs and prolonging the service life of plastic film.
