Study On Carbon Footprint For Mechanically Protecting Tillage System

LCA systematic evaluate agricultural environmental pollution factors generate by the process of agricultural production. LCA is the theoretical basis of carbon footprint analysis, it has the important guiding significance for the realization of low-carbon agriculture. The analysis of LCA based on the survey data of mechanically protecting tillage system in the central area of Jilin Province. analysis the carbon footprint based on the analysis of different conservation tillage patterns of carbon footprint.Carbon footprint evaluation results of different tillage pattern in the central area of Jilin province: High photosynthetic efficiency tillage pattern> Wide/narrow row pattern> Uniform row tillage pattern, it means that High photosynthetic efficiency tillage pattern have the greatest environment impact, Uniform row tillage pattern have the smallest environment impact. In the process of carbon footprint analysis, we found that the application of nitrogen fertilizer and the use of agricultural machinery have the greatest impact on the carbon footprint analysis of Maize Production Mechanization Conservation tillage. Therefore, it is necessary to increase the scale effect of maize planting, to provide the mechanical efficiency, and to implement quantitative fertilization, to enhance the use efficiency of nitrogen fertilizer.
