英文摘要 | Rice production is essential for ensuring food security. Nitrogen fertilizers applied in rice fields are prone to loss through NH 3 emissions. We need to elucidate the responses of NH 3 emissions to different N inputs. With a national dataset, we identified that N application rate, N application frequency, soil temperature, and soil silt fraction were the key driving factors of NH 3 emissions. 190-210 kg N ha -1 was suitable for simultaneously reducing NH 3 emissions and increasing rice yields. The model showed that under the actual N application rate and N application frequency of 3, national NH 3 emissions were 0.852 Mt N each rice growing season, while national NH 3 emission factor was 12.7 %. We developed a portable software to conveniently assess China 's NH 3 emissions from rice fields under different N inputs. The findings can help to optimize N inputs in rice fields to reduce NH 3 emissions and improve ecosystem health and agricultural sustainability. |
