| 摘 要： | 湖南郴州烟区烤烟苗期常遭遇低温和寡照气候的影响。为了提高苗期烟苗质量，在该地开展了苗期增温和补光试验。结果显示，漂浮育苗苗床增温处理可以显著提高烤烟出苗率，增强成苗素质，缩短成苗时间；补光处理也可一定程度提高烟株的成苗素质，降低漂浮育苗成苗时间，但对出苗率无影响，与常规育苗差异不显著；在郴州烟区，提高漂浮育苗水温，是增强漂浮育苗成苗素质的有效措施。 |
| 关 键 词： | 烤烟 光照 温度 漂浮育苗 成苗质量 |

| Abstract: | The effect of light and temperature of the flue-cured tobacco seedling was investigated to avoid growth retardation of tobacco seedling in float system, which is often caused by low temperature and short photoperiod in Hunan during spring. The results showed that increasing temperature could significantly improve flue-cured tobacco seedling emergence, seedling quality, and decrease seedling time. Also, additional light obviously improved seedling quality, and reduced seedling time. However, there was no effect on emergence rate. In summary, increasing water temperature in the late spring can obviously improve seedling quality in float system. |
| Keywords: | flue-cured tobacco light temperature float system seedling quality |
