摘要: 为了探索适宜武陵山区烟叶生产的最佳栽培行株距配置,采用田间试验,研究了烤烟不同行株距搭配对烟田微生态环境、烤烟光合特性及烟叶产值的影响。结果表明:(1)适宜的行株距配置能为烟株创造良好的烟田微生态环境;(2)行距0.12 m、株距0.40 m配置和行距0.12 m、株距0.60 m配置的叶片净光合速率最大,行距0.11 m、株距0.40 m配置和行距0.11 m、株距0.50 m配置的胞间CO2浓度较高,行距0.12 m、株距0.40 m配置的叶片蒸腾速率显著高于其他处理,行距0.11 m、株距0.60 m配置的蒸汽压亏缺显著高于其他处理;(3)从产量和产值上看,行距0.12 m、株距0.40 m配置表现较优,且其上等烟比例和均价都较高。综合分析,武陵山区烟叶适宜的栽培行株距配置为行距0.12 m,株距0.40 m。

Abstract: In order to explore the optimal flue-cured tobacco allocations of row-spacing in Wuling mountainous area, field experiment was conducted to study on effects of allocations of row-spacing on microecological environment in tobacco field,tobacco photosynthetic characteristics and output value of flue-cured Tobacco.The results showed that:?The suitable row-spacing was help to creat a good microecological environment for flue-cured tobacco.?The net photosynthetic rate (Pn) of 0.12×0.40m treatment and 0.12×0.60m treatment were higher.The intercellular CO2 concentration (Ci) of 0.11×0.40m treatment and 0.11×0.50m treatment were higher.The transpiration rates (Tr) of 0.12×0.40m treatment and the vapor pressure deficit (VPD) of 0.11×0.60m treatment were significantly higher than other treatments.?The performance of 0.12×0.40m treatment’s yield and output value was better.The high grade leaf proportion and average price of 0.12×0.40m treatment were higher.Comprehensive analysis,the optimal flue-cured tobacco allocations of row-spacing in Wuling mountainous area was row spacing 0.12m and spacing 0.40m.
