摘要
为探明不同材质烤烟育苗小棚对成苗质量的影响,精简烤烟漂浮育苗小棚制作过程并提高烟苗成苗质量,对竹制池梗拱棚、土夯池梗竹制拱棚和钢筋制池梗小拱棚漂浮育苗的温度、烟苗生育期、长势、出苗率和生物学性状等指标进行对比。结果表明:钢筋制池梗拱棚的干、湿球温度和水温适宜,成苗质量高,出苗率高达93.98%,茎高、茎围、侧根数和干物质积累均表现最好。
The temperature, seedling growth period, seedling growth vigor, emergence rate and biological characters of three floating seedling sheds （bamboo shed with bamboo pool sides, bamboo shed with soil pool sides and reinforcing bar shed with reinforcing bar pool sides） were compared to discuss the effect of floating seedling sheds with different materials on quality of flue-cured tobacco seedlings, simplify the production process of floating seedling sheds and improve flue-cured tobacco seedling quality. Results： The emergence rate of tobacco seedlings raised from the reinforcing bar shed with reinforcing bar pool sides is up to 93. 98% and its stem height, stem girth, lateral roots and dry matter accumulation is the best among three floating seedling sheds because dry bulb temperature, wet bulb temperature and water temperature of the reinforcing bar shed with reinforcing bar pool sides are appropriate.
