摘要
对河南省信阳市罗山县2010─2019年烤烟大田期(4─9月)的主要气象因子与烤后烟叶的理化性质进行了统计分析。结果显示:在不同年份间温度、日照时长、相对湿度较为稳定,而降水量变异系数较大;烟叶的总糖、还原糖、总植物碱、钾、总氮含量以及糖碱比较为稳定,而氯和淀粉含量变化较大;日照时长与烟叶拉力、含梗率、叶面密度、叶片厚度呈显著相关;平均气温和相对湿度与烟叶还原糖、总氮、总糖、总植物碱含量以及钾氯比呈显著正相关;月平均降水量对上部烟叶钾、植物碱、氯含量、糖碱比以及中部叶总糖、总氮、淀粉、钾含量、糖碱比影响显著;日照总长对上部烟叶总糖、总氮、淀粉含量以及中部烟叶糖碱比、氮碱比、钾氯比影响显著。
The main meteorological factors and physicochemical properties of flue-cured tobacco leaves during the field period(April to September)in Luoshan County,Xinyang City,Henan Province from 2010 to 2019 were analyzed statistically.The results showed that the temperature,sunshine hours,and relative humidity in Luoshan area in different years were stable,while the precipitation varied greatly.Among the main chemical components of tobacco leaves,total sugars,reducing sugars,sugar/alkaloid,total alkaloids,potassium and total nitrogen were relatively stable,while the content of chlorine and starch were highly various.The sunlight duration was significantly correlated with tensile force,rate of infarction,foliar density and leaf thickness.Average temperature and relative humidity were significantly positively correlated with the contents of reducing sugar,total nitrogen,total sugar,total alkaloids and potassium/chlorine.The average monthly precipitation had a significant effect on the potassium,total alkaloids,chlorine,sugar to alkaloids ratio of upper leaves and the content of total sugar,total nitrogen,starch,potassium and sugar/alkali of middle leaves.The total sunshine duration had a significant effect on the content of total sugar,total nitrogen and starch in the upper leaves and the sugar/alkali,nitrogen/alkali and potassium/chlorine of the middle leaves.
