| 摘 要： | 在有机烟叶生产中，为替代化学肥料，提高有机肥源在烤烟育苗中的利用效率，以烤烟育苗专用肥为对照(CK)， 研究沼液营养液氮浓度分别为50、150、250 mg/L 对烟苗生长及生理特性的影响。结果表明，与CK 相比，氮浓度为50 mg/L 的处理烟苗矮小，营养液中的养分难于满足烟苗生长的需要；氮浓度为150 mg/L 的处理烟苗长势较好，能显著增加烟苗根系的干、鲜质量，同时，总根长、根表面积、体积、根系活力均有不同的程度的增加。而叶片中光合色素含量、光合特性、 生理特性各指标与CK 相比差异不大。综合来看，氮浓度为150 mg/L 的处理能够达到使用漂浮育苗专用营养液的效果，可用于有机烟草育苗生产。

| Abstract: | This research is about the effects of different nutrient solution treatments on growth and physical characteristics of seedling,and the replacement of chemical fertilizers in organic tobacco production and the efficiency increase of organic fertilizer at seedling stage.Taking the specialty fertilizer for tobacco seedlings as CK,slurry were used as nutrient solution with 50 mg/L nitrogen concentration,150 mg/L nitrogen concentration and 250 mg/L nitrogen concentration.The results showed that: compared with C... |
