Abstract
The effect of nitrogen fertilization on yield and quality of wheat was studied in the different growth stages of wheat in Jiuquan city . The results showed that the amount of nitrogen topdressing can increase the total number of wheat stem,effective panicles per plant,grain number per panicle,1 000-grain weight and yield at different growth period under the condition of base application nitrogen was 120.0 kg/hm2,total nitrogen was 240.0 kg/hm2 . The yield were increased significantly by one-time topdressing nitrogen 120.0 kg/hm2 in the seedling stage,or nitrogen respectively 60.0 kg/hm2 in the seedling stage and jointing stage, it can increased 16.3% and 7.2% higher than of the check of no fertilizer,respectively,dressing nitrogen 60.0 kg/hm2 can improve coarse grain protein content,improve the quality of wheat in the flowering stage.关键词
