Abstract :
[zh] 【方法】供试黑土长期定位试验位于吉林省公主岭市,始于1990年。2018年选择其中不施肥(CK),施氮钾肥 (NK),施氮磷钾肥(NPK)和氮磷钾+有机肥(NPK+M) 4个处理小区,采集0-20、20-40和40-60 cm土层的 土壤样品,分析了土壤理化性质,采用恒温平衡法测定了土壤磷的吸附-解吸特征,并由此计算得到磷最大吸附 量(Q m)、吸附亲和力常数(K Q)、最大缓冲容量(MBC)、磷吸附饱和度(DPS)、最大解吸量(D m)和解吸率(D r)。 【结果】随着平衡溶液中磷浓度的增加,磷的吸附量与解吸量均呈先快速增加后逐渐趋于平衡的过程。与不施 磷处理(CK和NK)土壤相比,施磷处理(NPK、NPK+M)减少了磷的吸附量,增加了磷的解吸量。与不施磷处 理相比,施磷处理在0-60 cm剖面上的Q m 和MBC值分别降低了4.94%~63.46%和15.90%~75.18%,D r 值增 加了8.52%~474.0%,以NPK+M处理变化量最大。施磷处理比不施磷处理在0-60 cm土壤剖面上全磷和有机 质含量分别增加了34.40%~145.5%和12.77%~50.07%,游离态铁铝氧化物(Fe d +Al d)含量降低了 5.14%~11.35%。冗余分析表明,不施磷处理土壤的有机质、Fe d +Al d 和全磷,以及施磷处理中的Fe d +Al d 、络合 态铁铝氧化物(Fe p +Al p)、pH和有机质是影响磷吸附解吸特征参数的主要土壤因子,分别解释了不施磷和施磷处 理全部变异的77.59%和90.62%。土壤有效磷(Olsen-P)与磷吸附饱和度(DPS)相关关系表明,所研究的黑土
