摘要：	磷石膏是一种可以利用的磷化工废渣,本文以磷石膏为麦田温室气体减排剂,研究磷石膏对小麦生长、麦田温室气体二氧化碳(CO2)排放的影响,并分析磷石膏资源化利用的经济环境效益.结果表明,在常规施肥条件下,增施磷石膏2 100kg·hm-2能显著促进小麦生长,增产达37.71%.磷石膏对麦田CO2的减排作用在小麦生长的各个时期有所不同:施用磷石膏1 050 kg·hm-2处理,在小麦生长拔节期、抽穗期和灌浆期对麦田CO2的减排效果较为明显,相比对照分别减少8%、10%和6%;在整个小麦生长季累计减少CO2排放3%;施用磷石膏2 100 kg·hm-2处理,在小麦越冬返青期、拔节期和抽穗期,相比对照减少CO2排放11%、4%和12%,在小麦生长季累计减少CO2排放7%.磷石膏施用量较大的处理对CO2的抑制和减排效果较好.研究还表明在施用磷石膏的情况下,一定范围内,CO2的排放强度(单位鲜重CO2排放与单位产量CO2排放)与小麦穗长、鲜重和产量呈现显著负相关:即穗长越长,鲜重和产量越大,CO2的排放效率越低.在碳交易背景下,磷石膏资源化利用具有较高的经济和环境效益,主要体现在:与对照相比,投入/产出从1∶8.3变为1∶10.7,即在相同投入的情况下可提高28.92%的产出;每吨磷石膏作为麦田温室气体减排剂,可节省治理环境的费用与增产总额合计约290元.废渣磷石膏资源化利用,不仅可以减少环境污染、促进小麦生长,而且可以减少CO2排放,对发展低碳农业、生态农业以及可持续发展农业具有重要应用价值.
