Nitrous Oxide Emissions from Upland Farmland as Affected by Summer Legume Crop Cultivation
摘要
Abstract
A field study was conducted to investigate the effects of leguminous crop cultivation on nitrousoxide (N2O) emissions from upland agricultural soils. Results demonstrated that N2O emission sequences were tively. 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 much more N2O than non-legume upland rice treatment and that N fertilized treatments emitted more than unand N fertilizer, therefore, were one of the important sources of N2O emissions from agricultural fields.关键词
