凤阳烤烟产量和质量波动的气候因素分析

An Analysis of Climate Factors influencing in Yield and Quality of Flue-Cured Tobacco

本文采用统计学方法揭示凤阳烤烟生产与气候条件的关系，结果表明，４月份日平均气温、降水量和７月份降水量是影响烤烟产量的主要气象因子，７月份太阳总辐射能、８月份日平均气温、日照时数和太阳总辐射能是影响烤烟质量的主要气象因子，麦茬烟生长期间的热量条件远不及春烟优越。

Using statistical method, the relationship between meteorological condition andyield or quality of flue-cured tobacco in county Fengyang was studied. It was founad thatcounty Fengyang is one of the most appropriate to plant flue-cured tobacco. The averagediurnal temperature in April and rainfall amount in April and July are factors influencingonyield of flue-cured tobacco. The energy of Solar radiation in July and the average diurnaltemperature and sunshine and energy of solar radiation in August are factors influencing onquality of flue-cured tobacco. The thermal condition in period of growth of flue-cured tobacco planted after harvest of wheat is worse than spring tobacco.
