Abstract: This study means effects of nitrogen (N) on photosynthetic energy conversion efficiency, and photosynthetic performance of winter wheat. The average PN, gs and E of hole nitrogen rate N150 were the highest, reaching 4.71 μmol (CO2) mol–1, 20.69 μ mol m–1 s–1, respectively. Methods, The eastern part of the Shanxi Taigu was used to set four nitrogen application levels of 0 (N0), 120 (N120), 150 (N150), and 210 (N210) kg ha–1 before sowing. Two variety, (Variety Yunhan-20410, Yuhan-618). Result. The results from different parameters of research were showed, that the organic manure partial substitution for chemical fertilizer increased post-anthesis N uptake by 81.4 and 16.4% thus increasing the post-anthesis photosynthetic capacity and delaying leaf senescence. grain number per spikes by 11.5, 12.2%, and 1000-grain weight by 7.3 and 3.6%, respectively. The grain yield under organic manure partial substitution for chemical fertilizer treatment increased by 23, and 15%, respectively. Conclusion, The N120 at all stages of growth had significant effects on the Ci winter wheat flag leaf. The number of ears and grain number per spike were increased and the maximum values were achieved at N150, and nitrogen yield significant differences with the variety YH-20410, respectively.
