Abstract: To ensure the winter wheat（Triticum aestivum L.） with good quality, high and stable yield in Shijiazhuang city, the impacts of Duntianbao fertilizer on the growth was studied, and the effects of Duntianbao fertilizer on the growth period, dry matter accumulation and distribution, output and the index of yield formation and yield of winter wheat were discussed. The results showed that Duntianbao fertilizer spaying at setting stage could promote the growth and development of wheat before flowering; and spaying at the beginning of filling stage could extend grain filling stage and be helpful for output formation. In conclusion, proper application of Duntianbao fertilizer is an effective technical measure for increasing wheat yield.
