Abstract:
Soybean was used as material,the effect of chemical fertilizer (H),organic-inorganic complex fertilizers(HY) and straw combination with chemical fertilizer (HJ) on the emissions of greenhouse gas,soybean yield and quality was studied under an equal amount of nitrogen fertilizer.The results showed that for the greenhouse emission,CH4 seasonal emission flux of HJ increased 18.42%,32.35% than HY and H.CO2 season cumulative emissions fluxes of H,HJ and HY was 1 197.90 kg?hm-2,1 173.60 kg?hm-2,1 183.86 kg?hm-2,the differences of treatments were not significant.N2O season cumulative emissions flux of H compared with HJ,HY was higher by 37.5% and 35.09%.During soybean planting,the yield and quality of HY,HJ treatments were higher than H treatment,the yield increased 7.31% and 6.72%;the vitamin C,the protein content and the soluble sugar content were respectively increased 11.47% and 9.18%,12.80% and 12.60%,12.41% and 10.15%.A comprehensive consideration of the comprehensive effect of greenhouse gas (GWP),greenhouse gas emissions intensity (GHGI),soybean yield and quality index:straw combination with chemical fertilizer could significantly reduce greenhouse gas emissions and improve the yield and quality of soybean.As the largest renewable resource on earth,straw returning could improve ecological and economic benefits and reduce greenhouse gas emissions at the same time.
