本文利用1981～1984年贵州高原不同海拔的11个点的烤烟试验和气象同步观测资料,采用逐步回归分析,讨论分析了气象因子与烤烟品质的关系。结果表明:成熟期温度和全生育期≥20℃持续日数是影响烤烟质量最重要的气象因子,它们之间的定量关系非常明显。
In this paper, 11 points of flue-cured tobacco experiment and meteorological observation data from 1981 to 1984 at different elevations in Guizhou Plateau were used to analyze the relationship between meteorological factors and quality of flue-cured tobacco by using stepwise regression analysis. The results showed that the most important meteorological factors affecting the quality of flue-cured tobacco were the maturing temperature and the duration of ≧ 20 ℃ throughout the growth period, and the quantitative relationship between them was very obvious.
