摘 要:将≥20.0℃的初终日间隔日数、活动积温、降水、日照等作为铜仁优质烤烟种植气候精细区划的主要指标,根据1971~2010年全市10个气象站长序列气象资料和2005~2010年168个区域自动站的温度、降水等资料,把优质烤烟种植分为4个精细区:I区为最适宜区,完全具备优质烤烟种植的气候条件,温、水、光等配置很好,是铜仁高糖低一中碱清香型烟叶生产区;Ⅱ区为适宜区,具备优质烤烟种植的气候条件,温、水、光等配置较好,只是温度略有富余,是高糖中碱清香型烟叶的主要生产区;Ⅲ区为次适宜区,基本具备优质烤烟种植的气候条件,温、水、光等配置良好,只是温度较高,是中糖中碱清香型烟叶的主要生产区;Ⅳ区为欠适宜区,气候条件较差。According to the dominant meteorological factors, including the interval days between the first and last days ≥20.0 ℃ , accumula- ted temperature, precipitation, sunshine, etc. , the excellent tobacco planting areas can be divided into four regions based on the long-serious meteorological data of ten stations during 1971 -2010 and the data of 168 stations during 2005 -2010. Region I is the most suitable area with excellent allocation of temperature, rainfall and sunlight resources, it mainly produces the tobacco with high contents of sugar and low-medium contents of alkali; region 11 is the suitable area also with good meteorological conditions, but the temperature here is a little high, this area mainly produces the tobacco with high contents of sugar and medium contents of alkali ; region II is the less suitable area with basically good meteorological conditions, it mainly produces the tobacco with medium contents of sugar and alkali ; region IV is the worst area with the worst metrological conditions for growing flue-cured tobacco.
