储粮环境中CO_(2)产生与浓度变化关联因素影响研究

Research on the Variation of Carbon Dioxide Production and Concentration in Grain Storage Environment

CO_(2)是粮堆内重要的生态因子,其浓度变化主要是粮食籽粒、储粮害虫、微生物等生物因子呼吸的生理结果,因此,检测环境中CO_(2)浓度可反映粮堆内生物因子的发生发展情况。近年,因CO_(2)气体检测具有较高的敏感性和可靠性,以CO_(2)浓度变化作为粮情检测的技术手段,受到了越来越多的关注,CO_(2)浓度检测法作为粮情检测的一种方法,被运用于判断储藏谷物品质变化和虫霉害的发生。

CO_(2) is an important ecological factor in granary,and its variation is mainly the physiological result of respiration of grains,pests,microorganisms and other biological factors.Therefore,the detection of CO_(2) concentration in the environment can reflect the occurrence and development of biological factors in grain pile.In recent years,due to the high sensitivity and reliability of CO_(2) gas detection,more and more attention has been paid to using CO_(2) concentration as a technical means to detect grain condition.As a method of grain condition detection,CO_(2) concentration detection method has been widely used to judge the quality change of stored grain and the occurrence of pests and mildew.
