英文摘要Measurements of N2O emissions from conventional rice cultivation (CRC), CRC with straw mulching, system of rice intensification (SRI) and SRI with plastic film mulching were conducted through static chamber/gas-chromatography techniques. The results show that daily fluctuation of N2O emissions in jointing stage are much higher than in others. A type peak of N2O seasonal emission presented between jointing and bearing stages companying with high daily average temperature and low precipitation. Biomass and leaf stomatal conductance were observed. Total quantities of N2O emission were budgeted. The results showed that after jointing stage the average N2O emission flux of SRI with plastic film mulching increased significantly than CRC with straw mulching and SRI, the leaf stomatal conductance of those showed the same trend (p < 0.05). Yield and total quantity of N2O emission in CRC with straw mulching enhanced 13.7% and 10.7% compared with those of CRC, respectively. The total quantity of N2O emissions reduced 3.6% in SRI with plastic film mulching compared with CRC, however, the yield increase of that was not significant.
