Abstract: In order to study the influence of meteorological conditions on rice production and provide reference for rice planting in Nanling, Anhui Province, the main meteorological factors in the whole growth period of early season rice, middle-season rice and late season rice, double cropping late rice from 2005 to 2014 were analyzed. Then the correlation coefficients between meteorological factors and the meteorological yield of rice were calculated. The results showed that there was obvious inter-annual variability of rice meteorological yield with an increase trend of early season rice and double cropping late rice and a slight decrease trend of middle-season rice and late season rice. Comparative analysis and correlation coefficients suggested that meteorological yield of early season rice had negative and positive correlation with precipitation and evaporation, respectively, and the correlation was strong. Meteorological yield of middle-season rice and late season rice was affected by temperature, evaporation and precipitation obviously, and evaporation had the strongest effect. Meteorological yield of middle-season rice and late season rice had positive correlation with precipitation while had negative correlation with temperature, evaporation and sunshine duration. The correlation between meteorological yield of double cropping late rice and meteorological factors was relatively small. It was concluded that different meteorological factors impacted on rice growth in Nanling, and the results would lay a foundation for avoiding the meteorological disasters in rice planting.
