Returning agricultural waste is the important way of developing circular agriculture and low-carbon economy. In maize growth season, this study adopts the static method, such as NPK keep weight (N 240 kg/hm2, P2O5 100 kg/hm2, 120 kg K2O/hm2) conditions, straw, cow muck, chicken manure and chemical fertilizer was studied with soil and its influence on soil CO2 emissions and carbon fixation. The results show that the fertilizer promoted the soil CO2 emissions, 100% straw crushing returning NPK fertilizers (S1) promoting effect of soil CO2 emissions is most obvious, the average emission flux of 389.0 mg/m2?h; Followed by chemical fertilizer fertilization (S4). S1, S2, S3 and S4 handling in 6, 7, 8, three month average CO2 emission flux performance for S4 > S1 > S3 > S2, accounted for 80.1% of total emissions throughout the growing season, 78.9%, 78.8% and 78.9%, showed that fertilization of chemical fertilizer treatment (S4) in the maize growth season CO2 emission flux of up to 624.9 mg/m2?h. Various fertilizer treatments on maize growth season two CO2 emissions peak stage, is closely related to the two nitrogen fertilizer (urea) topdressing, twice topdressing nitrogen after CO2 flux values of performance for S4 > S1> S3 > S2, that use agricultural waste of nitrogen instead of nitrogen fertilizer, can reduce CO2 emissions. 50% cattle manure organic nitrogen application in the field with 50% nitrogen fertilizer (S2) can obviously increase soil organic carbon content. 50% chicken manure organic nitrogen application in the field with 50% nitrogen fertilizer (S3) can obviously improve the maize organs and plant carbon content, among them, the S3 processing plant carbon content up to 9.59 t/hm2, promoted the corn carbon fixation; While 100% straw crushing returning NPK fertilizer nitrogen (S1) does not improve maize organs and plant carbon content, and even lower than that of single chemical fertilizer (S4).
