A combination forecasting method was applied to forecast the corn crop yield and to achieve the objective for improving the precision of prediction.The weight of each model in the combination forecasting model was calculated with entropy theory.The forecasting results of all the methods were weighted and summed to gain the combination forecasting result,and the corn yield combination forecasting model was built.The combination forecasting model was used to examine the cron yield from 2000 to 2006,the forecast precision was obviously improved.The conclusion shows that it is feasible that a combination forecasting method is applied to forecast the corn yield.
