摘　　要：[目的]为降低育苗用工和提高烟苗素质,对烤烟漂浮育苗不同播种数量条件下的用工量及烟苗素质进行研究。[方法]设计3种播种数量(每穴播1粒、每穴2粒和每穴3粒包衣种)的烤烟漂浮育苗试验。[结果]在漂浮盘上每孔播1粒烟草包衣种的成苗素质要好于播2粒和3粒的,且其出苗率达96%以上。在人工播种情况下,播1粒包衣种用工量分别比播种2粒和3粒包衣种省工32.2%和41.7%,同时省去了间苗用工量。[结论]漂浮育苗每孔播1粒包衣种能提高烟苗素质,同时还能明显减少播种和间苗用工,从而达到育苗省工降本的目的。[Objective] In order to reduce the amount of labor and improve the quality of tobacco seeding,the effects of seeding quantity on the amount of labor and the quality of tobacco seedling in floating system were studied.[Method] The experiment of seeding quantity was conduced with three treatments（one seed sowing per hole,two seeds sowing per hole and three seeds sowing per hole）.[Result] The quality of tobacco seedling with one seed sowing per hole on plastic floating tray was better than those with two or three seeds sowing per hole,and the germinated rate was over 96%.The amount of seeding labor with one seed sowing per hole decreased by 32.2% and 41.7% than that with two and three seeds sowing per hole,respectively,the labor cost in thinning out seedling was also saved by one seed sowing per hole during seedling management.[Conclusion] Seedling with one seed sowing per hole in floating system could improve quality of tobacco seedling and decrease the amount of labor.
