Abstract: In order to study the effect of different basic seeding and nitrogen application on wheat plant traits, yield and protein components,used the multi-factor randomized block design,the experiment was carried out at the experimental farm of the Institute of Crop Sciences,Chinese Academy of Agricultural Sciences. The results showed that basic seedling 225 × 104-375 × 104 /ha within the grains per spike and grain weight decreased with the increase in basic seedling,grain yield increases with the basic seedling raised,significant difference among treatments; the Glutelin and total protein content with the basic seedling an increase in lower,albumin content changes in contrast,significant difference among treatments. the grain yield and crude protein content increased with the increase topdressing nitrogen,under the conditions of The base nitrogen 135 kg /ha and the topdressing nitrogen in 45-135 kg /ha. A(Variety) × C(topdressing nitrogen) in grain yield and crude protein content of a significant interaction,B(basic seedling) × C(topdressing nitrogen) in grain yield and crude protein content of interaction significant. The rate of Soluble protein(albumin + globulin) to the total protein content was 37. 03% ,and the soluble protein was significantly positive correlation(r = 0. 821**) to total protein,The rate of storage protein(Gliadin + Glutelin ) to total protein content was 55. 94% ,and the storage protein was significantly positively correlative to total protein(r = 0. 892**) . Albumin,globulin,gliadin and glutenin ratio of total protein were 23. 87% ,13. 17% ,25. 83% and 30. 11% ,the remaining protein, accounting for 7. 03% .

Key words: Basic seedling, Nitrogen application, Winter wheat, Yield, Protein components
