Based on the winter wheat yield data and meteorological data collected in Yining City from 1976 to 2019,the changes in winter wheat yields in the last 43 years in Yining were analyzed to obtain equations for calculating the trend yield of Yining winter wheat.During the identification of the key developmental periods and major influencing factors affecting wheat yield,the relationship between meteorological yield and meteorological factors was analyzed by selecting the decadal and monthly values of temperature,precipitation,and sunshine hours during the growth of winter wheat.By incorporating the growth and development process of wheat,the fac-tors for wheat meteorological yield forecasting were chosen,and a forecasting equation was constructed.Ultimate-ly,an equation for forecasting the winter wheat yield in Yining City was obtained.Further investigation using yield data from the previous four years demonstrated satisfactory precision in predictions,which could be applied to a variety of commercial applications.The findings of this study can contribute to guiding production,improving farmers'planting and field management practices for winter wheat,and offering a scientific basis for the authori-ties to make cogent decisions and ensure food security.
