Abstract: The weak winter ‘Zhengmai 9023’ is the first planting area varieties in north Henan, accounting for around 60% of the entire Maibo area, is the key of wheat yield in northern Henan. In order to improve the production of ‘Zhengmai 9023’ yield to formulate corresponding measures to provide a basis of science, by using different treatments between data was analyzed by variance analysis for 2010-2012 winter wheat sowing ‘Zhengmai 9023’ 2 test of the processing, studied and analyzed the effect of the meteorological factors on wheat growth key period, and wheat tillering, density, the real measurement investigation on ‘Zhengmai 9023’ yield factors. The results showed that: the ‘Zhengmai 9023’ suitable sowing date in October 15th to October 31st, affected ‘Zhengmai 9023’ key growth period of the main meteorological factors of sunshine was the dominant meteorological factor, which affected the filling speed. The temperature was a limiting factor, other meteorological factors generally played an indirect role.
