摘  要：
为优化烟草漂浮育苗技术,提高烟苗成苗素质,以中烟100为试验材料,研究不同水位深度及干湿交替漂浮育苗对烟苗生育期、成苗素质及其烤后烟叶经济效益的影响。结果表明,小十字期之后,随着育苗池水位深度的降低,漂浮育苗烟苗各项指标均向有利方向发展,其中以干湿交替漂浮育苗效果最好。采用烤烟干湿交替漂浮育苗技术,烟苗出苗期和出苗率与常规育苗无显著差异,但有利于烟苗根系发育;成苗期烟苗长势旺,根系强壮;成苗率提高1.6个百分点,壮苗率提高2.4个百分点;成苗时间较常规育苗缩短5d;螺旋根、病害以及苗池蓝绿藻发生率大幅降低;烤后烟叶上中等烟比例和均价较常规漂浮育苗分别提高了3.26个百分点和2.31元/kg;产量和产值分别增加了187kg/hm2、9 745.67元/hm2。烤烟漂浮育苗过程中,烟苗小十字期之后降低育苗池水位深度干湿交替,有利于成苗,增加产值。

摘  要：
The growth period,seedling quality and yield and quality of flue-cured tobacco were studied with Zhongyan 100 at different depths of water level for optimizing the floating system for tobacco seeding.The results showed that,with the decrease of water level in seeding pool,every index of tobacco seedling tended toward a favorable direction after little cross-seedling stage,and dry-wet alternation was the best for tobacco seedling.The dry-wet alternation had no significant difference in emergence stage and rate from conventional floating system for tobacco seeding,but it was of benefit to root development and the growth vigor.The root development and uniformity were better in seedling formation period.The rates of seedling and strong seedling increased by 1.6 and 2.4 percent points.Compared with control,the time of seedling establishment was shortened by 5 days.And the rate of spiral root,disease,and blue green algae occurrence decreased significantly.The dry-wet alternation method increased the first-class tobacco and average price by 3.26 percent points and 2.31 yuan/kg,and also increased the yield and output value by 187kg/ha and 9 745.67 yuan/ha.The way of dry-wet alternation of floating system for tobacco seedling was suggested to be beneficial to the seedling establishment and production value increase after little cross-seedling stage.
