摘　　要：以稻谷为样品,将直接烘干法中150℃/20 min与130℃/40 min和105℃恒重法水分测定结果进行了统计分析研究。试验表明对同一稻谷样品,采用150℃/20 min和130℃/40 min测试结果无显著差异;采用150℃/20 min和105℃恒重法测试结果亦无显著差异。因此在收购稻谷等实际应用中,为快速准确检测水分,可使用150℃/20 min定温定时烘干法。In this paper,three methods of moisture measurement were comparatively studied,including 150℃/20 min,130℃/40 min and 105℃/3 h+1 h(GB5009.3-2016:2-7).The test results showed that there was no significant difference between 150℃/20 min and 130℃/40 min for the same paddy sample.There was neither significant difference between 150℃/20 min and 105℃/3 h+1 h(GB5009.3-2016:2-7).Therefore,if the number of samples is large or it is emergency,150℃/20min can be used as a reliable method of moisture measurement for paddy.
