Abstract: To study- the meteorological tactors （temperature,rainfall and sunlight hours） of buckwheat production,the influenceof the six buckwheat varieties,including three wheat and three buckwheat planted tor two consecutive years in the sameregion, through observation of the reproductive period and record meteorological factors, determined agronomic traits in themature period, using the method of correlation analysis and path analysis, we tbund a clear correlation of buckwheat yieldand meteorological factors. Results showed that buckwheat production was greatly influenced by the environment, the mainmeteorological factors affecting the output was the sunshine time with a very significant positive correlation,it also showedpositive correlation between yield and temperature relation,and direct effect of meteorological factors was sunshine time 〉temperature〉precipitation.
