摘要
对三门峡烟区35 a来不同生育期气温和日照时数特征进行分析,结果表明:三门峡烟区不同年代气温和日照时数均以1980年代最低,日照时数以1990年代最高(1 272.91 h),气温最高值(21.72℃)出现在2000年以后.烤烟伸根期、旺长期和成熟期的日照时数在35 a间总体呈下降趋势,而气温呈上升趋势.
The 35 years data of temperature and sunshine duration under different growth stages in Sanmenxia tobacco-growing areas were analyzed.The results showed that temperature and sunshine duration in 1980s were the lowest under different decades.The maximum of sunshine duration was in 1990s(1 272.91 h) and the highest temperature value(21.72 ℃) occurred after the 2000s.The sunshine duration of root spreading stage,fast growing stage and maturing stage during 35 years showed decreasing trend,while the temperature showed increasing trend.
