摘要： 为解决长江中下游地区双季机插晚稻移栽秧龄过长的问题，选取温光特性及熟期各不相同的4个代表性品种为材料，研究不同秧龄移栽对双季晚稻生长及产量的影响。结果表明，随着移栽秧龄的增大，感温性水稻穂、成熟期均明显推迟，而感光型水稻生育期受影响较小；感温性迟熟品种25 天、30 天移栽产量显著下降，而感温性中早熟及感光性迟熟品种至30 天移栽产量才发生显著下降。最佳移栽秧龄为感温性晚稻15 天左右，感光性晚稻20 天左右。感温性品种作双季晚稻种植时应选用中早熟品种，而感光性品种可选用高产的中迟熟品种。

Abstract: The study aims to solve the problems of late transplanting rice with different seedling ages at the lower reaches of Yangtze River. Select six varieties of different thermal and photo-response characteristics as the test material to study the effect of different seedling ages on growth and yield of rice. The results showed that growing period of thermal-response rice was delayed by long seedling age, but less affected by the impact of photo-response rice; the yield of later thermal-response varieties with 25 days and 30 days seedling ages was significantly reduced. In contrast, the yield of early thermal-response varieties and later photo-response varieties was significantly reduced with 30 days seedling age. The optimal transplanting seedling age was 15 days of thermal-response rice, while photo-response rice was 20 days. The thermal-response rice should be selected as early maturing varieties, while the photo-response rice could be selected as late maturing varieties for high yield.
