摘要: 分析了南方红壤山地草业发展现状,论述了禾本科和豆科牧草对氮素的需求特点,南方红壤山地牧草施肥存在的问题和研究进展,阐述了N2O排放机制与影响因素。结合山地草业发展实际,提出今后进一步加强研究的若干思路。Abstract: It was important for pasture to scientifically apply nitrogen fertilizer and managing in red soil region.The development status of pasture was analyzed in details in red soils of southern China in the paper.On this basis,the paper overviewed the demand characteristic of pasture to nitrogen and principal questions existed in pasture fertilization,and systematacially expounded the N2O emission mechanism and influencing factors.Finally,combined with hilly pasture development,some questions strengthened for the future were discussed in order to provide scientific basis for sustaining development of modern pasture in the southern China.
