Annual CH4 and N2O Emissions from Double Rice Cropping Systems under Various Fertilizer Regimes in Hunan Province, China
不同施肥处理下双季稻田CH4和N2O排放的全年观测研究

Annual CH4 and N2O emission fluxes were measured from double rice cropping systems under six fertilization treatments by using the method of static chamber-gas chromatograph techniques.The different treatments including non-fertilizer(CK),conventional chemical fertilizers(NPK),fresh rice straw with chemical fertilizers(RS+NPK1),mushroom residue with chemical fertilizers(MR+NPK1),fresh cow dung with chemical fertilizers(CD+NPK2),and biogas digestion with chemical fertilizers(BD+NPK2) were dedicated to this e...
