摘　　要：贮藏室内适宜的贮藏温度是进行科学贮藏和决定贮藏质量的重要条件。为研究相同贮藏条件下不同质量马铃薯堆内部温度的差异,以内蒙古半地下式马铃薯贮藏室为试验场地,将食用型“冀张226”马铃薯按单薯质量进行分级,以筐装方式进行堆码,同时用传感器采集贮藏过程中的温度数据,然后对数据进行分析、对比。结果表明:整个贮藏过程中,分级后的所有马铃薯堆的内部温度整体变化规律基本一致,均为先降低后升高,但单薯质量小的马铃薯堆内部温度的稳定性要优于单薯质量大的马铃薯堆。温度下降阶段,马铃薯堆的内部温度与马铃薯单薯质量大小呈负相关;温度上升阶段,马铃薯堆内部温度上升率与马铃薯单薯质量呈正相关;不同马铃薯堆在贮藏过程中的最低温度与马铃薯单薯质量呈负相关;分级后的马铃薯堆内部温度的稳定性要优于未分级的马铃薯堆。Appropriate storage temperature in storage room is an important condition for scientific storage and quality determination.In order to investigate the differences of internal temperatures in potatoes heaps with different weights under the same storage conditions,the semi-underground potato storage room in Inner Mongolia was taken as the experimental site,and the edible potatoes of‘Jizhang 226’were graded according to the weights and stacked in baskets,meanwhile,the temperature data in storage process collected using sensors were analyzed and compared.Results showed that the internal temperatures of graded potatoes piles during the whole storage process presented similar change pattern,which was firstly reduced and then increased.However,the internal temperatures of graded potatoes piles with lower weights showed superior stability than that with higher weights.During the temperature decreasing stage,the internal temperatures of potatoes piles were negatively correlated with the weight of single potato,while during the temperature rising stage,the temperature rising rates in potatoes piles showed positive correlation with the single potato weight.Besides,the minimum temperatures of potatoes piles were negatively correlated with the single potato weight during the storage process,and the internal temperature stability of graded potatoes piles was better than that of the ungraded potato piles.
