以5个粳稻品种为材料，采用分期播种的方法，从稻米品质的角度，探讨了豫南地区粳稻适宜播种期。结果表明，随着播种期的推迟，供试的5个品种糙米率、精米率总体上呈增加的趋势，而垩白度、垩白粒率以及垩白大小呈明显的降低趋势；粒长和长宽比在不同播种期下变异较小；胶稠度基本上是以Ⅱ期或Ⅲ期播种的最长；直链淀粉含量和碱消值在不同播种期虽然差异较大，但无明显的变化规律。模糊概率法综合评价结果显示，各品种稻米综合品质随着播种期的推迟表现出提升的趋势，均是以Ⅳ期或Ⅴ期播种的模糊概率最高。说明在豫南地区，适当推迟播种期，有利于提升粳稻的综合品质。

The appropriate sowing date of japonica rice in Southern Henan was studied in the perspective of rice quality. The results showed that the brown rice rate and milled rice rate of the five japonica varieties showing increasing trend, as the sowing date post-poned, the chalkiness degress, chalky rice rate and chalkiness size showing a significant decreasing trend. The coefficient of variation of grain length and length-width ratio were small. Gel consistency in Ⅱperiod or Ⅲperiod was the largest. The amylose content and alkali value had great difference under different sowing date, but there was no significant regular changes. The result of fuzzy proba-bility method showed that the quality of five japonica varieties were increased as the sowing date was postponed,and the quality ofⅣorⅤsowing date were the best.
