摘要:

本研究聚焦农业生产中的碳足迹及氮肥利用问题,为旱稻低碳生产提供理论依据。采用生命周期评估(Life cycle assessment, LCA)方法对吉林某地旱稻碳足迹(Carbon footprint, CFP) 进行核算。结果显示,1 kg吉林旱稻从旱稻种植到产品加工的碳足迹为0.4721 kg CO2-eq,主要源于氮肥生产和土地排放,二者分别占比39.71%和20.41%。综上可知,旱稻相比水稻没有甲烷排放,具有减排效应。优化肥料选择、合理减少氮肥施用、施用控释肥、添加硝化抑制剂、有机肥合理替代化肥等措施是进一步实现旱稻碳减排的重要途径。

Abstract:

This study focused on carbon footprint and nitrogen fertilizer utilization in agricultural production, providing theoretical support for low-carbon production of dry rice. The carbon footprint (CFP) of the production process of upland rice was calculated by using life cycle assessment (LCA) methodology. The results showed that the carbon footprint of 1 kg Jilin upland rice from planting to product processing was 0.4721 kg CO2-eq. The carbon footprint of upland rice was mainly derived from nitrogen fertilizer production (39.71%) and land emission (20.41%). In conclusion, compared with rice, upland rice had no methane emission and had emission reduction effect. Optimization of fertilizer selection, rational reduction of nitrogen fertilizer application, application of controlled release fertilizer, addition of nitrification inhibitor, and rational substitution of organic fertilizer for fertilizer were important ways to further achieve carbon emission reduction of upland rice.

Key words: upland rice, life cycle assessment, carbon footprint, carbon emission reduction
