由于受四季气候变化的影响,为了达到低温储粮的标准,利用冬季低温季节对储粮进行通风降温,一般将平均粮温降至10℃以内,目的是为储粮安全度夏打好基础。但随着冬去春来气温不断上升,储存的粮食温度在次年7~9月达到30℃左右,对储粮品质的影响较大,如何经济有效地缓解粮温回升,延 Due to the seasonal climate change, in order to achieve the standard of low temperature grain storage, the use of winter cold season ventilation of grain storage and cooling, the average grain temperature is generally reduced to 10 ℃, the purpose is to lay a solid foundation for the safety of stored grain. However, as the temperatures went up in winter and spring, the temperature of stored grain reached about 30 ℃ in July and September next year, which had a great impact on the quality of stored grain. How to effectively and economically reduce the grain temperature rise and delay
