| 摘 要： | 本文利用生命周期评价的方法分析了苹果修剪枝条堆肥处理模式的环境影响,并分析其肥料化潜力与经济效益,对枝条处理各环节进行污染物排放评估,为苹果修剪枝条肥料化处理工艺的改进提供参考。研究结果表明：苹果修剪枝条堆肥处理过程中,每处理功能单位苹果枝条产生的污染物总量为76.0219kg,其中CO2的排放量占总排放量的96.79%,全球变暖对环境的影响高于酸化与富营养化；粉碎包装、熟化灭菌、粉碎、堆肥阶段产生的污染物气体排放量分别占总排放量的38.26%、27.22%、21.04%、10.85%；功能单位苹果修剪枝条堆肥处理的生产成本为515元/t,经济效益为285元/t,可替代尿素、过磷酸钙、硫酸钾的量分别为61.30、120.00、13.20kg。

| Abstract: | In order to provide reference for the improvement of apple pruning branch fertilization treatment process, the article analyzed the environmental impact of apple pruning branch fermentation composting treatment mode by using life cycle assessment, and assessed fertilization potential, economic benefits and the pollutant emissions of each step of branch treatment. The results showed that the total amount of pollutants produced per functional unit of apple pruned branches treatment was 76.0219 kg, CO2 emissions accounted for 96.79% of the total emissions, which led to a higher impact of global warming on the environment than acidification and eutrophication. The pollutant gas emissions from the crushing and packing process, autoclaving of materials, branch crushing and composting process stages accounted for 38.26%, 27.22%, 21.04% and 10.85% of the total emissions respectively. The treatment cost of the functional unit of apple pruning branch was 515 RMB/t and the economic benefit was 285 RMB/t, could replace the urea, calcium superphosphate and potassium sulphate by 61.3, 120 and 13.2 kg respectively. |
