Plot experiment was carried out to study the effect of soil water regime and soil texture on N₂O emission from rice paddy field in Fengqiu ecological experimental station, Chinese Academy of Sciences in 1994. The results showed that N₂O emission was mainly affected by soil water regime.N₂O emission was very low when the soil was flooded, while N₂O emission during soil drying period accounted for as high as 87.50%-98.65% of the total seasonal N₂O emission. Soil texture significantly influenced N₂O emission from rice psddy field.N₂O emission from sandy soil was significantly higher than that from loam and clay soils. Seasonal mean N₂O fluxes from sandy, loam and clay soils were 137.63, 87.54 and 63.46μg N₂O-N·m^-2·h^-1 respectively.
