Influence of Different Fertilization Modes to Corn Production and Greenhouse Gas Emissions

This paper discusses the influence and difference between dryland corn of conventional and control fertilizations bio-charcoal in production and greenhouse gas emissions,the results show that soil N2O and CO2 from field is a net emissions from field in the entire observation period,and CH4 is a net absorption.N2O emissions are mainly in one month after the base manure,accounting for more than 70% of the total emissions of the entire season.The emissions of N2O are significantly different between the two fertilization modes,Compared with the conventional fertilization,the total N2O emissions of the application of the regulation fertilization decreased by 70.3%,but it shows no significant influence on CH4 and CO2 emissions.The carbon intensity of corn production of the regulation of fertilization was significantly reduced by 73.91%,while production increased significantly.
