Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
An experiment was carried out with treatments differing in nitrogen supply (0, 5 and 15 gN/m2) and CO2 level (350 and 700 μmol/mol) using OTC (open top chamber) equipment to investigate the plant-soil carbon fixation in freshwater marsh Sanjiang Plian after two years. Results showed that elevated atmosphere CO2 concentration increased plant biomass and the response of biomass to enhanced CO2 concentration differed in N levels. Both the increase of aboveground biomass and belowground biomass were greater under high level of N supply (15 gN/m2). Elevated CO2 concentration increased the amount of plant carbon fixation and the increase was 19.3%, 24.4% and 24.6% with NN, MN, and HN respectively. Elevated CO2 concentration also increased the allocation of biomass and carbon in belowground parts. The variations in soil organic carbon was not significant and merely increased 0.5-1.8% under nitrogen addition.
