摘要：
A field study was conducted to investigate the effects of leguminous crop cultivation on nitrous oxide (N2O) emissions from upland agricultural soils. Results demonstrated that N2O emission sequences were that peanut crop> soybean>upland rice in terms of N2O-N flux, being 25.9, 21.2 and 18.4μg/m2·h respectively. While in terms of seasonal emission, the sequence was that soybean > peanut crop >upland rice, being 0.77, 0.70 and 0.55 kg/ha respectively. Results also demonstrated that legume crop treatment emitted
