常规烤烟小棚育苗受天气影响大，在黔西南州育苗阶段早春低温和后期高温严重影响壮苗培育。黔西南州山洞资源丰富，利用其温度相对恒定的特点开展漂浮育苗，规避灾害天气。该研究选用黔西南烟区常规品种云烟85，开展常规育苗和山洞育苗对比试验。结果表明：山洞育苗能提高烤烟出芽率，缩短出苗时间，增加物质积累，提高烟苗均匀性，降低苗床病害发生率。

Flue-cured tobacco floating-seedling in little canopies was greatly affected by changing weather. Flue-cured tobacco seedling was affected by low temperatures in early spring and high temperatures in late spring in Qianxi′nan. Qianxi′nan was rich in cavern resources ,making use of cavern′s temperature constancy for floating-seedling could avoid natural calamities. This research chose the ordinary variety of flue-cured tobacco Yunyan85 for contrast test between ordinary floating-seedling and cavern floating-seedling. The results indicated that cavern floating-seedling could improve germination percentage of flue-cured tobacco ,curtail germinating time ,increase matter accumulation ,decrease growth differentia and disease incidence rate of flue-cured tobacco seedlings.
