烤烟缓释肥料对烟株根系和光合特性的影响

Effect of slow-release fertilizer on the root system and photosynthesis of flue cured tobacco

  • 摘要: 试验研究了烟草缓释肥料对烟株根系活力、叶片光合特性、烟株干物质积累以及产量和产值的影响。结果表明, 施用烟草缓释肥料可显著提高烟株根系活力、叶片叶绿素含量和净光合速率以及烟株干物质的积累, 降低胞间CO2浓度, 其中以每株施用45.45 g 烟草缓释肥料的效果最好, 其次为每株施用38.63 g烟草缓释肥料。施用烟草缓释肥料能提高烟叶的产量和产值, 减少烟草缓释肥料用量的处理虽然降低了烟叶产量, 但因改善烟叶品质而提高其产值, 缓释肥料对烟叶产值的影响以每株施用38.63 g烟草缓释肥料处理效果最好。

     

    Abstract: The effect of slow-release fertilizer on the root system, photosynthetic characteristics and dry-matter accumulation in flue-cured tobacco was studied. The yield and output value of flue-cured tobacco leaf were also analyzed in the experiment. The results show that slow-release fertilizer increases tobacco root activity, chlorophyll content, net photosynthetic rate and dry-matter accumulation while reducing inter-cellular CO2 concentration in flue-cured tobacco leaf. 45.45 g slow-release fertilizer for per plant has the most favorable impact on roots, leaf photosynthetic characteristics and dry-matter accumulation. Also 38.63 g slow-release fertilizer for per plant positively influences these variables. Yield and output value of the leaf are enhanced by slow-release fertilizer. Although yield of tobacco leaf decreases with decreasing application amount of slow-release fertilizer, tobacco output value increases due to the production of high quality tobacco leaf. 38.63 g slow-release fertilizer for per plant has the best effect on tobacco output.
