Regulation Effect of Cultivated Measures on Grain Yield and Baking Quality in Bread Wheat

ZHAO Guang-Cai 1 HE Zhong-Hu 1 WANG De-Sen 1 ZHANG Yan 1 ZHOU Gui-Ying 1 TANG Xiu-Wei 2 LIU Hui-Mian 2( 1 Institute of Crop Breeding and Cultivation, CAAS, Beijing 100081; 2Agricultural Administration of Baodi County Tianjin City, Baodi 301800, China)  
The experiments of fertilizer, water and chemical regulation on grain yield and baking quality in high quality bread wheat, showed the main result that the treatment of fertilizer and water were important to grain yield and quality. In the conditions of same nitrogen application and watering, the grain yield, protein content, wet gluten content, sedimentation, stability and bread volume were increased with nitrogen application at late growth stage and heavy dressing at elongation stage. The grain yield was increased but the protein content and bread volume were decreased with increasing the watering times. Foliage spraying properly Zhuangfeng′an could decrease the plant height, prevent lodging. Moreover, it mainly resulted in shortened internode under the rachis internode, with forming good plant shape, and increasing the number of ear bearing tiller, but decreasing the per ear grain number. In the moderate condition of soil fertility, increasing nitrogen application could raise effectively the grain yield, however, increasing either nitrogen or phosphate application could raise the bread volume and bread score.
