摘　　要：文章利用达拉特旗1981—2010年的小麦产量资料及气候资料进行统计,运用相关分析及逐步回归方法,得出灌浆期的日照时数是影响小麦产量的主要原因,播种期的气温和出苗期的风速是次要因子。运用上述气象因子建立小麦气候产量的综合关系方程,并进行检验,拟合精准度在90%以上。Based on the the field data of spring wheat and climate data covering the period from 1981 to 2010,correlation analysis and Stepwise regression method were used.The result showed that the wheat field was mainly determined by sunshine hours of filling stage,the temperature of sowing date and wind velocity of emergence stage which played a secondly role on the yield formation of wheat.An equation was elucidated by the meteorological factor and climatic yield.Test results showed that the precision was more than 90%.
