Abstract
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(1272.91 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.
