1994年在中国科学院封丘生态试验站通过小区试验研究了土壤质地和水分状况对稻田N2O排放的影响。结果表明稻田N2O排放主要受土壤水分状况的影响，淹水状态下，N2O排放很少，水分落干期间N2O排放量占水稻生长期N2O排放总量的87.50%～98.65%。土壤质地显著影响稻田平均N2O排放通量，砂质土壤排放的N2O显著或极显著高于壤质和粘质土壤，水稻生长期砂质、壤质及粘质土壤的平均N2O排放通量分别为137.63、87.54和63.46gN2O朜／m2·h。

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 paddy 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 63.46g N2O-.m－2.h－1, respectively.
