水稻新品种试验是育种者筛选和鉴定选育品种和品种审定的关键环节，产量是衡量品种优势的重要指标。本文以湖南省水稻区域试验早稻组、一季晚稻组品种为材料，对试验产量结果进行分析，研究含水量对产量的影响情况。结果表明，含水量高低直接影响了各品种产量，两种计算方法的产量差异达显著水平，按照标准含水量来统一折算产量的方法能有效避免多种因素对产量的影响，真实地反映各品种产量情况。

The new variety test of rice is the key process of screening and identification breeding varieties, and the yield is an important index to measure the superiority of varieties. In this paper, two group regional rice varieties of Hunan Province, early rice and one-cropping late rice, were used as materials to analyze the effects of water content in grain on rice yield. The results showed that the water content of early rice and late rice directly affected the yield of each variety, and the difference between the two methods was significant. According to the standard water content, the method of unified conversion of yield could effectively avoid the influence of various factors on yield and truly reflect the yield of each variety.
