研究了以聚苯乙烯泡沫板作为保温材质，铺垫于漂浮育苗池下方和四周，以常规漂浮育苗方法为对照，分析两者对整个生长历程及烤后烟叶质量的影响，结果表明：铺垫聚苯乙烯泡沫板处理的出苗率高达94．18％，苗龄缩短8 d，育苗池温度平均提高2．17℃，移栽时烟苗素质显著好于对照烟苗；此外，大田期烟株的农艺性状和烤后烟叶经济性状都有明显的优势。% The polystyrene foam board was used as the adiabatic material for the temperature -keeping floating seedling -rea-ring of flue-cured tobacco, and it was installed under and around the seedling -rearing pool.This method was called as tempera-ture-keeping floating seedling -rearing method here.The conventional floating seedling -rearing method was taken as the control , and the influences of two methods on the whole growth process of tobacco plants and the quality of flue -cured tobacco leaves were compared.The results showed that: in comparison with the control , after using temperature -keeping floating seedling -rearing method, the seedling emergence rate was up to 94.18%, the age of seedlings was shortened by 8 days, the temperature of seedling-rearing pool was increased by 2.17 ℃, the quality of transplanted seedlings was significantly improved , and the agronomic traits of the tobacco plants in field period and the economic traits of flue -cured tobacco leaves had obvious advantages .
