摘  要：
为研究过磷酸钙不同添加量对蔬菜废弃物堆肥过程中氨气和温室气体排放的影响,以生菜的废弃菜叶和玉米秸秆为原料,以过磷酸钙肥料为添加剂,进行了27 d的曝气供氧堆肥,对堆肥过程中的氨挥发和温室气体排放(N2O、CH4和CO2)进行了监测.试验共设6个处理,除CK处理(不添加过磷酸钙)外,其余处理依次根据混合物料初始总氮物质量的5%、10%、15%、20%和25%的比例添加过磷酸钙.结果表明:添加过磷酸钙对减少堆肥过程中的氨挥发和温室气体排放均有明显效果,氨挥发总量较CK减少了4.0%~16.7%,总温室气体CO2排放当量减少了10.2%~20.8%.堆肥过程中排放的NH3对温室效应的贡献相对较大,各处理NH3的CO2排放当量为59.90~81.58 kg·t-1,占4种气体总CO2排放当量的69%~77%.蔬菜废弃物堆肥过程中适量添加过磷酸钙是减少氨挥发和温室气体排放并提高堆肥品质的有效措施.

摘  要：
To study the effects of superphosphate( SP) on the NH3 and greenhouse gas emissions,vegetable waste composting was performed for 27 days using 6 different treatments. In addition to the controls,five vegetable waste mixtures( 0. 77 m3each) were treated with different amounts of the SP additive,namely,5%,10%,15%,20% and 25%. The ammonia volatilization loss and greenhouse gas emissions were measured during composting. Results indicated that the SP additive signi-ficantly decreased the ammonia volatilization and greenhouse gas emissions during vegetable waste composting. The additive reduced the total NH3 emission by 4. 0% to 16. 7%. The total greenhouse gas emissions( CO2-eq) of all treatments with SP additives were decreased by 10. 2%to 20. 8%,as compared with the controls. The NH3 emission during vegetable waste composting had the highest contribution to the greenhouse effect caused by the four different gases. The amount of NH3( CO2-eq) from each treatment ranged from 59. 90 kg · t-1to 81. 58 kg · t-1; NH3( CO2-eq)accounted for 69% to 77% of the total emissions from the four gases. Therefore,SP is a cost-effective phosphorus-based fertilizer that can be used as an additive during vegetable waste composting to reduce the NH3 and greenhouse gas emissions as well as to improve the value of compost as a fertilizer.
