【摘要】 土壤源CH₄氧化主要受土壤理化性状、温度、施肥种类和施肥量、作物品种及其生长状况、重金属离子种类与浓度等因子的影响。这些因子主要通过影响CH₄氧化细菌群、种类、数量、活性及其分布模式产生作用。合理施用有机肥、调节田间水分、配施矿质肥料以及培养根系活力较强的高产水稻品种是减少土壤源CH₄排放量的主要措施。更多还原

【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.更多还原
