Abstract:

Five rice samples were selected and baked in a drying box oven at 80℃ for 0.5 h, 1.5 h, 3.5 h, 6.5 h, 10.5 h, 22.5 h and 34.5 h after drying, obtain the data by weighing and measuring moisture content respectively. The results indicated that the moisture content measured immediately after drying is lower than measured after a certain period of time，and converted to the standard water yield is too high through PM-8188New Capacity Grain Moisture Measuring Apparatus. From the test results, it is advisable to measure the moisture content 22.5 h after the drying.

摘要：

抽取5只样品稻谷，在80℃烘干箱中烘1.5 h。在烘干结束后0.5 h、1.5 h、3.5 h、6.5 h、10.5 h、22.5 h、34.5 h应用PM-8188New谷物水分测量仪分别称重、测含水量获得相关数据。结果表明，在烘干后马上就测水分，比放置一定时间后再测，得出的含水量偏低，折算标准水分得到的产量偏高。从本试验结果看，水稻尤其是超级稻的验收测产以烘干结束后22.5 h再测含水量为宜，可作为相关产量验收办法的补充。
