摘要：

To find out how the weather influences the winter wheat yield, the authors used the time series data from the years 1981-2009, such as rainfall and temperature. The simple linear regression model with trend was to be established to estimate the relation between yield and meteorological factors. According to the result, the temperature has positive influence except on sowing stage in October but rainfall have negative influence except during jointing stage in April. We could forecast the yield according to weather factors; based on the meteorological yield coefficients we also considered irrigation or film-covering to increase temperature so as to increase the wheat yield. This will give a theoretical basis for crop yield forecasting and the way to increase yield. In summary, this study could be used in the earlier warning for wheat yield. © 2013 Asian Network for Scientific Information.
