Abstract:Soil-borne methane(CH4) oxidation is affected by factors such as soil physic-chemical characters,temperature,fertilizer type and amount,crop varieties and their growth, kinds and concentration of heavy metals ions,and so on.These factors exert action through influencing CH4 oxidation bacteria, types, amount, activity and distribution models. The measurements for reducing CH4 flux are to apply organic manure and matter, control field moisture, apply mineral fertilizer and evolve rice varieties with high yield.
