运用描述统计、简单相关和典型相关统计分析方法,研究了保山烟区主要气象因子与烤烟化学成分含量的关系。结果表明:①保山烟区气候条件适宜,气候特点有利于优质烤烟的种植;②光、温和水气象因子对烟叶化学成分的影响为:气温> 降雨量> 日照;气象因子对蛋白质、钾氯比、还原糖和总氮影响较大,其中7月的气象因子对化学成分含量影响最大;③烟叶蛋白质与5 ~ 7月气温、9月日照时数和7 ~ 8月降雨量呈显著负相关;还原糖与5月降雨量和5 ~ 9月平均气温呈显著负相关,与7月降雨量呈极显著正相关;总氮与5月气温、9月日照时数和7 ~ 8月降雨量呈显著负相关;钾氯比与8 ~ 9月气温呈显著正相关,与7月日照时数呈显著...

Taking the descriptive statistics, simple correlation and canonical correlation analysis as methods, this paper studied the relationship between major climatic factors and chemical compositions of flue-cured tobacco in Baoshan. The result indicated that ① climate in Baoshan was suitable for planting high-quality flue-cured tobacco. ② the influences of climatic factors on tobacco leaf chemical composition were in the following order： temperature〉 precipitation〉sunshine; protein contents, ratio of potassium to chlorine, reducing sugar and to...
