摘要
The solar global radiation from 1957 to 2006 was calculated in Fushun region and its seasonal,geographical and inter-annual variation were analyzed.Moreover,relationship between yield and solar energy use efficiency of rice,corn and soybean were analyzed concretely.The results showed that Fushun County had the most solar global radiation in Fushun region,while Xinbin County had the least.The solar global radiation in warm season accounted for 72% of the total solar radiation in one year.The maximum solar global radiation occurred in May,while theminimum value in December,with a period of 19 years.In addition,crop yield was proportional to solar energy use efficiency.
