土地规模化经营对农业碳排放的影响机制

The Effect mechanism of large-scale management to agricultural carbon emissions

土地规模化经营是影响农业碳排放的重要因子,研究土地规模化经营对农业碳排放的影响机理对降低农业碳排放有非常重要的促进作用。理论分析认为,土地规模化经营主要是通过作用于农业生产的具体活动来影响农业碳排放,包括化肥与农药的生产和使用,农田灌溉,农业机械使用、秸秆利用等方面。经过科学计算与分析,土地规模化经营中对农业碳排放影响最大的方面是秸秆的利用,其次为化肥生产与使用,农机使用,农田灌溉和农药生产与使用。为了促进我国农业减排事业的发展,建议国家在实施土地规模化经营的过程中,应提高秸秆的综合利用率,降低化肥和农药生产与使用量,推行滴灌等节水型灌溉措施,提升农业机械的利用效率等。

Large-scale management is a very important factor to impact agricultural carbon emissions,so the study of the influence mechanism of large-scale management to agricultural carbon emissions would promote the reduction of agricultural carbon emissions by a big step.After the theoretical analysis,we think the influence of large-scale management on agricultural carbon emissions is realized by acting on the specific activity of agricultural production,including the produce and use of fertilizer and pesticide,field irrigation,the use of farm machinery,the use of straw and so on.After the scientific calculation and analysis,we think the most impact of large-scale management to agricultural carbon emissions is the use of straw,after is the produce and use of fertilizer,the use of farm machinery,field irrigation,and the produce and use of pesticide.To promote the progress of agricultural carbon emissions,states should pay attention to some points when we put large-scale management into effect,about to enhance the rate of multipurpose utilization of straw,reduce the amount of the produce and use of fertilizer and pesticide,carry on trickle irrigation or other water-saving irrigations,elevate the utilization ratio of farm machinery and so on.
