摘要
为探究切花向日葵种植碳足迹和经济效益,调研切花向日葵种植企业,利用生命周期评价法评估露地、拱棚和日光温室3种不同生长条件下切花向日葵碳排放,核算生产成本和效益.结果表明,露地切花向日葵种植碳足迹2 174.46 kg/hm2、种植成本 51 994元/hm2、收入 178 608元/hm2;拱棚切花向日葵种植碳足迹 2 041.13 kg/hm2、种植成本 59 443元/hm2、收入 175 973元/hm2;日光温室切花向日葵种植碳足迹 2 038.92 kg/hm2、生产成本 58 465元/hm2、收入 179 544元/hm2.3种不同生长条件下切花向日葵种植的主要成本均来自人工、种子、土地、肥料和设施租金,碳排放最主要的来源均为有机肥和氮肥.在未来切花向日葵种植中,可通过优化生产技术提高肥料利用率,研发专用机械降低劳动力投入,增加轮作等途径来实现减排增收的目的.
Abstract
In order to explore carbon footprint and economic benefits of cut flower sunflower production,carbon emissions of cut flower sunflower under three different growing of open field,arch shed and solar greenhouse were evaluated by life cycle assessment method,and production cost and benefit were calculated.Results showed that carbon footprint of cut flower sunflower production in open field was 2 174.46 kg/hm2,production cost was 51 994 yuan/hm2,and income was 178 608 yuan/hm2.Carbon footprint of sunflower produc-tion in arch shed was 2 041.13 kg/hm2,production cost was 59 443 yuan/hm2,and income was 175 973 yuan/hm2.Carbon foot-print of sunflower production in solar greenhouse was 2 038.92 kg/hm2,production cost was 58 465 yuan/hm2,and income was 179 544 yuan/hm2.Main cost of cut flower sunflower production under three different growing conditions came from labor,seeds,fer-tilizer and land rent,and main sources of carbon emissions were manure and nitrogen fertilizer.In the future production of cut flowers and sunflowers,purpose of reducing emissions and increasing income could be achieved by optimizing production technology,improv-ing fertilizer utilization,developing special machinery,reducing labor input,and increasing crop rotation.
