摘要
明确棉花//花生间作的主要碳排放环节,可为实现棉花//花生间作高产与低碳排放的协同效益提供有效参考措施.本文构建了碳足迹模型,按照全生命周期方法,核算了新疆棉花//花生间作生命周期碳排放.结果 表明:棉花//花生间作的净收益约为棉花单作的1.4倍、花生单作的1.2倍;棉花//花生间作的单位面积碳排放达4878.4 kg CO2-eq/hm2,较棉花单作降低10.9%、花生单作降低4.1%,但单位净产值的碳排放为0.4 kgCO2-eq/元,较棉花单作降低66.6%、花生单作降低29.6%.综合2种种植体系的净收益和单位净产值碳排放发现,棉花//花生间作可以实现高产出与低碳排放的协同效益,符合绿色、高产、高效农业发展需求.
Clarification of the main carbon emission under cotton/peanut intercropping system can provide reference on taking effective measures to achieve the synergistic benefits of high yield and low carbon emission. Based on the full life cycle assessment, a carbon footprint model was constructed and the carbon emission of cotton/peanut intercropping in Xinjiang were calculated. The results showed that the net income of cotton/peanut intercropping was 1.4 times of cotton monoculture and 1.2 times of peanut monoculture. The carbon emission of per unit area of cotton/peanut intercropping was 4878.4 kg CO 2-eq/ha, which was 10.9% and 4.1% lower than that of cotton and peanut monoculture, and the carbon emission of per unit net income was 0.4 kg CO 2-eq/yuan, which was 66.6% lower than that of cotton monoculture and 29.6% lower than that of peanut monoculture. These results indicate that cotton/peanut intercropping could achieve the synergistic benefits of high yield and low carbon emission, which meet the requirement of green, high yield and high efficiency agricultural development.
