[目的]研究不同施氮量对不同品种的冬小麦籽粒的蛋白组分以及加工品质的影响。[方法]在较高土壤肥力的条件下,以2个强筋小麦品种临优145和郑麦9023,两个弱筋小麦品种宁麦9号和宝丰949为材料,设置三种氮肥用量（0、150和300kg/hm2）,测量冬小麦籽粒蛋白质含量、蛋白组分含量和比例以及加工品质。[结果]增施氮肥有利于提高籽粒蛋白质及其各组分的含量。总蛋白质、球蛋白、醇溶蛋白和谷蛋白含量均随着施氮量的增加显著提高,清蛋白含量也随施氮量的增加而提高,但不同施氮水平下差异不显著。氮肥施用量对小麦籽粒各组分在总蛋白中所占比例的影响不大,各蛋白组分在籽粒总蛋白中所占比例相对稳定。增施氮肥能够提高面粉的沉降值、湿面筋含量、面包体积和面包评分,降低小麦籽粒的容重。[结论]为形成优质专用小麦技术体系提供理论依据。

[Objective] This study aimed to explore the effects of nitrogen fertigation rate on the protein components in grains and processing quality of different wheat varieties. [Method] Under the condition of higher soil fertility, different amounts of N-fertilizer were applied in the plots, and then the contents of total protein and its components, percentage of the component content to total protein content as well as the processing quality of grains of two strong-gluten wheat varieties （Linyou145 and Zhengmai9023） and two weak-gluten wheat varieties （Ningmai9 and Baofeng949） were determined. [Result] The contents of total protein and globulin, gliadin and glutenin were improved significantly with the increase of the N-fertilizer amount; but the content of albumin did not show remarkable increase; in addition, the percentage of each protein component was relative stable and did not increase significantly. Increase in the amount of N-fertilizer improved the sedimentation value, wet gluten content, loaf volume and loaf score, decreased the volume weight of grain. [Conclusion] This study provideed theoretical support for high-quality wheat production.
