稻谷容重能反映稻谷籽粒的大小、形状、整齐度、胚乳质地等品质性状，与含水量等指标也密切相关。采用6个正常成熟收获的籼稻品种，研究不同干燥方式下，稻谷容重与含水量的关系。结果表明：（1）相同干燥方式下，稻谷容重因品种不同而不同，含水量为14.5％时，供试品种 LP5容重最大，为552.8 g／L，LP7容重最小，为534.2 g／L。（2）相同品种的稻谷容重因干燥方法不同而不同，采用自然晾晒方式，当含水量在23％～17.5％时，容重缓慢降低；含水量在17.5％～10.5％时，容重升高较快；此后容重随着含水量降低极缓慢升高。采用45～50℃烘箱间歇式烘干降水时，当含水量在23％～14.5％时，容重随含水...

To assess the relationship between rice grain test weight and moisture content under different drying methods, six indica hybrid rice varieties were analyzed for test weight and moisture content. The results showed that rice grain test weight was closely related to moisture content in grain. Rice grain test weight varied with varieties. The highest was the va-riety of LP5 with the rice grain test weight 552.8 g/L and the lowest was the variety of LP7 with the rice grain test weight 534.2 g/L when the rice grain with moisture content of 1 4.5%wi...
