Abstract: The paper aims to study the impact of meteorological conditions on rape production, and provide references for agricultural meteorological services special on rape production. Based on rape production and meteorological factors such as temperature, precipitation, sunshine and daily range from 2001 to 2015 in Xuancheng, the authors analyzed the relationships between the meteorological factors and meteorological production of rape by Excel and SPSS software. The results showed that: the inter- annual meteorological production of rape fluctuated greatly; there was a significantly negative correlation between the meteorological production of rape and the precipitation at the flowering stage and the maturity stage; the meteorological production of rape was positively correlated with the average temperature during the growth period, especially with the average temperature at the budding stage through the test of 0.05, there was also a significantly positive correlation between the meteorological production of rape and the sunshine hours at vegetative growth stage and daily range of temperature at the maturity stage. During the whole growth period, the meteorological production of rape was positively correlated with the temperature, sunshine and daily range, and was negatively correlated with precipitation; the correlation coefficient with temperature was the most significant through the test by 0.05, followed by sunshine and precipitation.
