为解决烤烟漂浮育苗技术在高海拔烟区育苗时间长、成苗素质差的问题。本试验采用湿润育苗技术提高烤烟成苗素质，农家肥发酵增热法缩短育苗时间，提高成苗素质。结果表明：采用农家肥发酵增热发酵+湿润育苗法可提升池水温度4-5℃，缩短苗龄8 d，苗高增高4.45 cm、茎围增粗0.46 cm、侧根系发达。本方法能缩短烤烟漂浮育苗时间，提高烟苗的素质，适宜在本县高海拔烟区推广应用。

To solve the problems of long seedling culture time and poor quality of tobacco seedlings bred by floating culture technique of seedlings in high-altitude to-bacco areas, a comparative trial between seedling nursing on moist trays + fermen-tation heating using farmyard manure and conventional floating culture of seedlings in Fenggang County was carried out in 2013. The results showed that seedling nursing on moist trays + fermentation heating using farmyard manure can improve 4-5 ℃ of pool water temperature, shorten 8 d of seedling age, increase 4.45 cm of seedling height, thicken 0.46 cm of stem girth and make lateral root system devel-oped. The method can shorten the time of floating breeding of flue-cured tobacco, improve the quality of tobacco seedlings, thus it was suitable to popularize in high-altitude tobacco areas of Fenggang County.
