摘　　要：通过对储粮通风时间减少百分比指标的确立并对储粮通风温度条件进行评价,得出以下结论:①通风时间和温差呈双曲线规律变化;②温差小于8℃时,所需通风时间过长,不宜进行机械通风;温差大于8℃时,所需通风时间明显缩短,可以根据实际情况选择通风时机对粮食进行机械通风。The percentage of mechanical ventilation time decreasing was determined and the temperature eondition was evaluated. It shows： （1） There is a pattern of hyperbolic curve rule between ventilation time and temperatures difference. （2） When the temperatures difference is less than 8℃, it should not conduct mechanical ventilation because of excessive time, when the temperature difference is more than 8℃, the aeration time can be shortened obviously. So it is very important to choose temperature conditions in mechanical ventilation.
