云南省大气臭氧变化及其对烤烟生长和化学品质的影响研究

The atmospheric ozone variation and its effect on the output,the chemical constituents of the flue-cured tobacco in Yunnan

  • 摘要: 选取了在云南省广泛栽种的云烟85和K326两个典型的烤烟品种作为考证样本,利用位于滇中的楚雄地区可靠的1990~1998年烤烟单位产量及品质数据资料及同期昆明Dobson观测站的臭氧总量的实测数据,考虑到烤烟的生长期,相应选择了4~8月份的UVB月平均观测值来探讨臭氧量与烤烟生产的关系.基于此,着重分析了UVB月平均观测值的变化与烤烟的产量、上等烟的比例、以及烟草化学成分的相关关系.研究结果显示:臭氧总量的增减可以影响烤烟产量;大气臭氧变化对烤烟的化学品质也有一定影响;而制约烤烟生产的其他自然因素的综合影响应当予以关注和研究.

     

    Abstract: In the research,two typical flue-cured tobacco varieties Yunyan 85 and K326 were selected as the research samples in view of they are widely planted in the whole province.The research material was based on the output and quality data of the flue-cured tobacco collected in Chuxiong City in the years of 1990~1998,and the ozone total quantity data measured by Kunming Dobson Observation Station in the corresponding period.Concretely,the 4~8 month is the main growth time of the flue-cured tobacco,the monthly mean observation of UVB in the same term was selected to check up the correlativity between the ozone quantity variation and the flue-cured tobacco planting.Having analyzed the correlations between the monthly UVB change and the flue-cured tobacco per hectare yield,the first-class tobacco proportion,as well as the tobacco chemical constituents respectively,It argued that there exists an evident negative correlation between the quantity variation of the atmospheric ozone and the flue-cured tobacco output,the first-class tobacco proportion.Furthermore,the atmospheric ozone variation seemed to potentially affect the growth and the chemical composition accumulation of the flue-cured tobacco.Regardless of other natural conditions,the analysis suggests that the flue-cured tobacco growth and its chemical constituents shows a response to the quantity variation of the atmospheric ozone.Whereas flue-cured tobacco growth is a complex progress,further study on the influence of the combination of the natural factors is still required.
