猪、鸡规模化养殖生产过程碳排放源解析及减排路径研究OA
Analysis of Carbon Emission Sources and Reduction Pathways in Large-Scale Pig and Chicken Production System
猪、鸡规模化养殖是我国畜牧业的支柱产业,在保障"菜篮子"工程稳定供给、支撑城乡居民肉类消费需求方面发挥着关键作用.随着我国加快构建低碳友好型社会,推动畜牧业绿色低碳转型已成为时代发展的必然要求.实现猪鸡养殖环节的低碳发展,乃至迈向猪鸡养殖碳中和目标,不仅是畜牧业高质量发展的核心方向,更是落实"双碳"战略的重要组成部分.本文就猪、鸡规模化养殖的碳足迹进行综述,从源头、过程和终端全链条解析其碳排放来源,其中饲料生产加工、运输和粪污处理是碳排放的重点环节,3 种排放源所占比重超过 80%.针对上述关键排放源,亟需构建低碳导向的全产业链减排路径,具体措施包括:建立可靠的供应链体系、降低运输距离与车辆空载率、提高农田精细化管理、减少化学肥料的施用、采用有机种植方式减少投入品使用、提高再生能源的使用比例、优化加工工艺参数降低饲料厂能耗、采用节能环境控制设施设备、提高粪肥管理、提高动物生产效率等.
Large-scale pig and poultry farming is a pillar industry of China's animal husbandry.It plays a crucial role in ensuring stable supply for the"vegetable basket"project and in meeting the meat consumption needs of residents.As China accelerates the building of a low-carbon and eco-friendly society,promoting the green and low-carbon transformation of animal husbandry has become an inevitable requirement of the times.Achieving low-carbon development in pig and poultry farming,and even moving toward the goal of carbon neutrality in these sectors,is not only a core direction for the high-quality development of animal husbandry,but also an important component of implementing the national dual carbon strategy.This paper reviews the carbon footprint of large-scale pig and poultry farming,analyzing the sources of carbon emissions across the entire chain:from the origin,to the process,and to the terminal stage.Feed production and processing,transportation,and manure treatment are identified as the major emission stages,with these three sources accounting for more than 80%of total emissions.To address these critical emission sources,it is urgent to construct a low-carbon oriented,full-industry-chain emission reduction pathway.Specific measures include:establishing reliable supply chain systems,reducing transportation distances and vehicle idling rates,improving precision farmland management,reducing the application of chemical fertilizers,adopting organic farming practices to minimize input use,increasing the proportion of renewable energy usage,optimizing processing parameters to reduce feed mill energy consumption,adopting energy-efficient environmental control facilities and equipment,improving manure management,and enhancing animal production efficiency.
