摘　　要：运用机械通风技术对农户小粮仓"丰产仓"储藏的高水分稻谷进行通风降水试验。结果表明:采用风压600Pa,风量5m3/min的离心风机(功率200W),利用单管通风道通风,在通风时间为110～120h条件下,可以将新收获的稻谷水分从18%～19%左右降至10%～13.5%,对稻谷裂纹率无影响,可以解决我国农村农户高水分稻谷在应急条件下的降水问题,从而达到安全储藏要求。This test focused decreas of the high moisture of freshly hervested paddy stored in farm bin by mechanical ventitation. The results showed that the moisture content of paddy sample can be decreas from 18 -19% to 10-13.5% after single tube ventilation for 110-120h with centrifugal fan at 600Pa pressure, 5m^3/min air flow and 200W power, without bad effect on crack rate. Thus, the conclusion can be got that this method can be used in farm storage to handle with the high moisture paddy as an emergency approach.
