针对高温高湿地区筒仓中粮食储藏安全的问题，进行了偏高水分玉米控温的试验。结果表明：偏高水分玉米初春入仓后，应首先将粮食水分降至14.5％左右；然后启动内环流系统将内圈筒仓的粮温维持在20℃以下、外围筒仓维持在25℃左右；盛夏期间当偏高水分粮或杂质分级点引起局部发热时，可利用谷冷机进行降温散湿。另外，可将偏高水分玉米储于不受外部环境影响的内圈筒仓，配以加强入仓粮食清杂和提前进行预防性熏蒸等措施，以提高湿粮储藏的稳定性。

The temperature control test of high moisture corn was carried out, and storage security problems of grain in silos in hot and humid regions were studied. The results showed that grain moisture should be reduced to about 14.5% firstly after high moisture corn was warehoused in early spring. And then the grain temperature should be controlled by internal circulation system, inner silos maintained below 20℃, external silos maintained at about 25℃. When high moisture grain or impurities grade point caused local heating, we could reduce the grain temperature and moisture by grain cooler during the height of summer. Additionally, in order to improve the storage stability of wet grain, high moisture corn should be stored at internal silos which were not affected by external environment, and enhance the grain cleaning, advance preventive fumigation.
