Effect of nitrogen application on grain yield and quality of high quality wheat Ⅱ Effect of nitrogen application on quality
Abstract：The experiments were conducted to study the effect of nitrogen applying date and applying amount on grain quality and flour quality with the varifies, Jinan 17, 955159 that have high quality for making bread and the new line 935031 that has high quality for noodle. Two experimental sites were selected based on different ecological, climatic enviroments and soil properties. The result showed that both the applying date and amount of nitrogen affected most of the quality characteristics. The grain quality and flour quality were improved greatly for nitrogen application from stem elongation to flag leaf emergence stage compmed with early inter- nod elongation stage. Same amount of nitrogen that divided into two times for top - dressing even got better result to protein content, wet gluten contem, sedimentation value and stability time. Nitrogen applying amount arranged from 150kg to 300kg per hectare could improve quahty to certain degree than that in lower nitrogen application level. It's still an effective measure to improve quality by high - level nitrogen application under the conditions of high or middle soil properties.
