| Abstract: | A field experiment was conducted by second-order central designed with composite orthogonal rotational matrix for two variables to investigate the effects of quantity coupling between water and N under AINP(alternate irrigation and N Placement) on soil NH3 volatilization and N2O emission and summer maize yield.The gaseous N was collected by open-bottomed chambers made from PVC in field.NH3 was absorbed in the chamber with boric acid and then titrated with dilution H2SO4 in the lab.A 5mL sample of headspace ... |
