摘要
本文以太湖流域上游地区为例,应用生命周期评价方法对比分析了生产1t水稻采用传统施肥技术和测土配方施肥技术对环境造成的影响。结果表明:与传统施肥技术相比,测土配方施肥技术可以降低环境影响综合指数,从0.116减少到0.083;环境影响指数削减率由大到小依次是环境酸化、富营养化、温室效应及能源消耗。受一些因素影响,虽然减小幅度不大,但是测土配方施肥技术有效地减少了能源消耗和环境污染。因此大力推广这一环境友好型农业生产新技术是实现农业生产和环境保护协调发展的可选择路径之一。
Taking upper reaches of Taihu Lake Basin as an example and using Life Cycle Assessment(LCA) methodology,this paper calculated and compared the environmental impacts of producing one ton of rice with different fertilization technologies.Results indicated that:Compared to the conventional fertilization technology,the soil testing and formula fertilizer recommendation technology reduced aggregate environmental impact index from 0.116 to 0.083 and the reduction rates in descending order were environmental acidification,eutrophication,global warming and energy consumption.Under the influence of some factors,though the reduction rates were not big,this new fertilization technology effectively reduced energy consumption and environmental pollution.Therefore promoting the adoption of this environment-friendly technology is one of the options for the coordinated development of agricultural production and environmental protection.
