基于中国农业科学院红壤实验站红壤旱地小麦-玉米轮作长期定位试验,采用静态箱/气相色谱法,研究红壤旱地连续施肥16 a后,不同施肥条件下小麦季和玉米季土壤CO2和N2O的排放特征。结果表明,CO2和N2O排放具有明显的季节性,施肥对土壤CO2和N2O排放有明显影响,且有机肥的施用显著促进了土壤CO2和N2O排放。不施肥对照(CK)、氮磷配施(NP)、氮钾配施(NK)、氮磷钾配施(NPK)和有机无机肥配施(NPKM)处理小麦季和玉米季土壤CO2累积排放量分别为5 904、8 062、4 298、9 235、14 098和4 708、7 530、5 435、7 089、15 472 kg.hm-2,土壤N2O累积排放量分别为0.34、0.63、0.44、0.62、1.00和0.25、0.39、0.35、0....

Fluxes and cumulative emissions of CO2 and N2O from red soil during the wheat and corn seasons under different patterns of long-term fertilization (CK, NP, NK, NPK and NPKM) were monitored by making use of the long-term, 16-year wheat-corn rotation experiment on upland red soil in the Qiyang Red Soil Experiment Station, Chinese Academy of Agricultural Sciences. The static dark chamber method and gas chromatograph technique were used to collect and measure concentrations of CO2 and N2O. Results show that emissions of CO2 and N2O varied obviously...
