摘　　要：比较了粮库储粮早期霉变监测4种主要方法的特点,通过对各种方法特征的分析,将储粮早期霉变监测方法分为"粮食取样监测"和"粮堆可传导物监测",前者适用于散粮或对粮堆表层特殊部位粮食的检测,后者更适合对整仓储粮进行监测。研究了各种方法监测储粮霉菌活动的敏感性,结果表明,在相同的储藏条件下,微生物活性检测至少可比平板菌落计数法提前3 d或更早了解储粮中霉菌危害活动的信息;粮堆中霉变原点二氧化碳监测比温度监测方法可提前10 d发现检测值的显著变化(P<0.05),并且二氧化碳气体在粮堆中的扩散速度明显高于温度在粮堆中的传导速度。The characteristics of useable methods for monitoring early fungi growth of stored grain spoilage in warehouse were compared. All four kinds of techniques were classified into ＂grain sampling monitoring＂ and ＂fungi metabolic production monitoring＂. The results showed that the former was adapted to be used in unpaekaged grain or special position of surface layer in grain pile, and the latter was fit for all grain bulk of warehouse or tank. The sensi- tivity of all methods for monitoring fungi activating had been investigated finding the information of fungi harming stored grain by ＂microbe activity than by ＂plate colonies counts＂. The carbon dioxide detecting in grain bin （ P 〈 0.05 ） 10 days earlier than grain pile temperature detecting at mould in grain pile was obviously faster than temperature transmitting the pile. , which leaded out a results indicating that detecting＂ could be 3 days at least earlier could find out the values significant change growth point, and carbon dioxide diffusion
