The Greenland–Iceland–Faroe Ridge,located between the central eastern part of Greenland and the northwestern edge of Europe,spans across the North *** the core component of the Greenland–Iceland–Faroe Ridge,the Iceland is an alkaline basalt area,which belongs to the periodic submarine magmatism and submarine volcano eruption resulting from mantle plume upwelling(Jiang et al.,2020).For the oceanic plateaus,the characteristics of the Iceland are closest to the continental crust,so the Iceland is considered the most suitable for simulating the earliest continental crust on the Earth(Reimink et al.,2014).

目的:分析秸秆直接还田对农田径流中氮磷及COD向周围水体迁移情况的影响。方法:分别设置田间试验CK(无秸秆还田+无施肥)、F(常规施肥)、SDF(秸秆覆土还田+常规施肥)、SMF(秸秆覆盖还田+常规施肥)、SFR(秸秆覆盖还田+常规施肥减量15%)等5个处理。研究水稻秸秆还田对小麦季农田径流氮磷及COD的影响。结果:秸秆还田处理可显著降低氮素质量浓度,增加磷素和COD的质量浓度;秸秆还田较常规施肥处理组总氮质量浓度下降14.34%~28.09%,总磷浓度升高8.70%~17.39%,COD浓度升高13.32%~32.33%。秸秆还田处理可显著降低农田径流流失量,秸秆还田较常规施肥处理径流量显著降低17.05%~19.08%。秸秆覆土还田配施化肥处理有效降低农田氮磷的风险,较F处理,SDF处理的总氮流失量下降33.37%,总磷流失量下降6.32%,COD流失量增加了5.24%。结论:秸秆覆土还田配施化肥是一种合理的施肥方式,为秸秆资源合理化利用提供参考。
