中文摘要	为阐明长期施用氮磷钾化肥(NPK)以及化肥有机肥配施(NPKM)对土壤无机磷组分的影响,采用蒋柏藩-顾益初无机磷分级体系,观测了我国6种典型农田土壤-红壤,紫色土,潮土,塿土,灰漠土和黑土15年长期施肥土壤无机磷形态和Olsen-P含量的变化.NPKM能比NPK更显著地增加土壤中全磷含量;能显著提高土壤Ca2-P的含量,在塿土中其提高量是NPK处理的4.07倍.施肥主要是增加了Ca8-P,Al-P和Fe-P含量,红壤Al-P,Fe-P增加量最大,分别达到237.7 mg kg-1和277.7 mg kg-1;NPKM对增加土壤Olsen-P含量的效果更加显著,在黑土和红壤中,其含量分别高达121.4 mg kg-1和98.4 mg kg-1;塿土和黑土Olsen-P含量比试验开始时分别增加了18.4和9.1倍.化肥有机肥配施对增加无机磷各组分和速效磷含量效果显著,主要增加Ca8-P,Al-P和Fe-P等活性较高的无机磷,黑土和红壤中Olsen-P含量达到较高水平, Ca8-P,Al-P或Fe-P为Olsen-P的主要磷源
英文摘要	Changes of inorganic phosphorus under long-term combined application of chemical and organic fertilizer were studied. With a scheme developed by Jiang Baifan and Gu Yichu for fractionalizing inorganic-P in calcareous soil, changing mechanics of inorganic phosphorus with the situation of 15-year long-term fertilization in 6 typical arable soils(Red Soil, Purple Soil, Fluvo-aquic Soil, Loess Soil, Grey desert Soil and Black Soil) in China were studied. Combined application of chemical and organic fertilizer(MNPK) had increased total phosphorus more significantly than chemical fertilizer(NPK).Ca2-P increased significantly in the MNPK treatments, and reached 4.07 times than NPK treatments in loess soil. Fertilization mainly increased the content of Ca8-P, Al-P and Fe-P.The largest increases were the contents of Al-P and Fe-P in red soil, which was reaching to 237.7 mg kg-1 and 277.7 mg kg-1. Olsen-P increased significantly in MNPK treatments in all kinds of soils, which was reaching to 121.4 mg kg-1 and 98.4 mg kg-1 in black soil and red soil. Olsen-P also increased 18.4 and 9.1 times than original soil in Loess soil and Black soil. With the combined application of chemical and organic fertilization, all forms of inorganic phosphorus and Olsen-P increased significantly in the six kinds of soils, especially Ca8-P, Al-P and Fe-P.The content of Olsen-P reached a higher lever in black soil and red soil. Ca8-P and Al-P or Fe-P was main sources for Olsen-P
