Abstract: The aim was to analyze the temperature changes and different sowing dates on the Huojia County wheat growth and yield of the impact by using linear analysis methods. The 1960-2010 years temperature data from statistics showed that the average temperature and maximum temperature was significant warming in winter and spring, summer, but decreased, the minimum temperature all year round performance for the warming trend. Through the 2010-2011 winter wheat phased seeding experiments, analysis of the impact of meteorological factors on wheat growth and development of identified wheat suitable for sowing, the author identified key growth period for the Huojia County wheat meteorological factors temperature appropriate indicators, to identify the main meteorological factors affecting the production of wheat late grain filling stage. Sunshine was filling rate of the leading meteorological factors, temperature was a limiting factor, and other meteorological factors affected the general indirect effects, and provided the basis for the development of appropriate scientific measures to improve wheat production in the production.
