In order to improve crop yield,this study analyzed the effects of biochar application on crop yield and GHGI through experimental analysis.Firstly,the experimental area was determined and the research methods were introduced.Then,based on this,the effects of biochar application on crop yield and GHGI were analyzed from the aspects of climate factors,field management and biochar application.The variance analysis was carried out from the rice growth stage,dry crop planting stage and the whole crop rotation cycle.Through research,it was found that when the biochar dose>80t/ha and C/N≥80,the GHGI index of the surrounding environment was the lowest;while applying biochar,applying an appropriate amount of inorganic fertilizer to the soil can significantly increase crop yield and reduce the GHGI index of the surrounding environment.Through the application of the test results,it can provide support for China to better carry out agricultural production work,increase crop yield,and reduce the damage of agricultural production to the natural environment.
