Abstract
Due to the depletion of stratospheric ozone layer and its slow process of recovery,extensive work has been done to understand the effect of enhanced UV-B(280～320 nm)radiation on agricultural ecosystem.However,so far no report has been available regarding the influence of enhanced UV-B radiation on diurnal variations of respiration rate and N2O emission.With static chamber-gas chromatography method,field experiments were carried out to investigate the influence of enhanced UV-B radiation on diurnal variations of respiration rate and N2O emission from wheat field ecosystems.Results indicated that,an obvious diurnal variation of respiration rate was observed in soilwinter wheat system and soil,but not changed with the enhanced UV-B radiation,except for the inhibition of respiration rate.On sunny days with large difference in daily temperature,N2O emission also showed a diurnal variation,but not changed with the enhanced UV-B radiation.At jointing,booting and heading stages,enhanced UV-B radiation significantly declined daily mean soil respiration rate(P=0.000,0.004,0.022,respectively)but had no significant impact on daily mean respiration rate or N2O emission from soil-winter wheat system as well as daily mean N2O emission from soi(lP0.05).While the daily mean respiration rate and N2O emission from soil-winter wheat system as well as soil were not found to be significantly different at flowering under enhanced UV-B radiation(P0.05).At filling stage,enhanced UV-B radiation significantly declined the daily mean respiration rate by 23%(P=0.049)and N2O emission by 48%(P=0.017)from soilwinter wheat system as well as the daily mean N2O emission by 37% from soi(lP=0.027)but had no significant impact on daily mean soil respiration rate(P0.05).
