针对江南地区夏季高温时间较长、粮堆上层粮温极易升高、玉米耐储性差的情况,利用空调制冷技术对夏季高温玉米进行控温,使整仓玉米平均粮温控制在20℃以下,最高粮温点控制在25℃以下。与对照仓相比,试验仓改善了高温季节玉米仓的储粮环境,整个夏季试验仓虫害达到基本无虫,脂肪酸值变化较小,减缓了玉米品质劣变,同时达到年度免熏蒸,实现绿色储粮,社会效益明显。
Aiming at the long time of high temperature in summer in Jiangnan area, the upper grain temperature of grain is extremely easy to increase and the storage tolerance of corn is poor, the temperature of summer high temperature corn is controlled by air conditioning and refrigeration technology so that the average grain temperature of whole grain corn is controlled below 20 ℃ , The maximum grain temperature control at 25 ℃ below. Compared with the control warehouse, the trial warehouse improved the storage environment of corn in the high temperature season. The insects in the trial warehouse reached basic insects throughout the summer and had little change in the fatty acid value, which slowed down the deterioration of maize quality and achieved the annual fumigation-free and green Grain storage, social benefits obvious.
