In order to explore the effects of straw returning combined with fertilizer on soil nutrients and winter wheat yield in Guanzhong area, an experimental split plot design was utilized. The main consisted no (S0) (S). sub-regions (WF), nitrogen (NF), phosphate (NPF). Ecological stoichiometry used study relationship between carbon, nitrogen, phosphorus content, under conditions. results showed that fertilization interactions had significant organic total contents surface layer (0-20 cm) (P<0.05). Compared S0WF treatment, SNPF treatment significantly increased carbon interaction year content With increase time, 0-20 cm SWF higher than Straw their 20-40 (P>0.05). affected P chemical also a effect stoichiometry. S0NPF decreased C:N C:P N:P cm). SNF reduced yield. 2020 2021, production by 24.23% 28.9%, respectively, compared treatment. Correlation analysis positively correlated (P<0.05) (P<0.01). At same were years (P<0.001). conclusion, (SNPF) can improve nutrient characteristics, change stoichiometric area. Therefore, this indicate is effective way optimize regional farmland management grain capacity.
