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 flue-cured tobacco seedling raising technology in high-altitude tobacco growing area for a long time, the problem of poor quality of seedlings. In this experiment, moist seedling raising technology was used to improve the quality of seedlings of flue-cured tobacco. The method of fermentation by heating manure fertilizer shorten the time of seedling raising and improve the quality of seedling. The results showed that the heating and fermentation by farmyard manure could increase the temperature of the pond water by 4-5 ℃, shorten the seedling age by 8 days, increase the seedling height by 4.45 cm, and increase the stem circumference by 0.46 cm with developed lateral root system. The method can shorten flue-cured tobacco seedling raising time and improve the quality of tobacco seedlings, and is suitable for popularization and application in the high-altitude tobacco area of the county.
