摘  要:
采用修正的Hedley磷素形态分级方法,研究了不同培肥处理对土壤各形态磷的影响。研究结果表明,施肥处理对土壤中各种磷素形态都有提高,但不同处理提高的幅度不同,其中,对活性态磷(H2O-P+NaH-CO3-P)的提高幅度依次为:无机肥+有机肥+菌肥>无机肥+菌肥>无机肥+有机肥+基质>无机肥+有机肥>无机肥>CK,对中等活性态磷(NaOH-P)的提高幅度依次为:无机肥+有机肥+菌肥>无机肥+有机肥>无机肥+菌肥>无机肥+有机肥+基质>无机肥>CK。无机肥+有机肥+菌肥处理与对照相比,对土壤的活性态磷和中等活性态磷分别提高了149.6%和73.3%。

摘  要:
According to the improved classification of soil phosphorus method proposed by Hedley in this thesis,effects of different fertilization treatments on different kinds of soil phosphorus forms were studied.It turned out that different fertilization treatments could improve the content of all kinds of phosphorus forms in the soil.The effects of the treatments on(H2O-P+NaH-CO3-P): inorganic fertilizer+organic+microbial fertilizer>inorganic fertilizer+microbial fertilizer >inorganic fertilizer+organic+matrix > inorganic fertilizer + organic > inorganic fertilizer>CK.The effects of the treatments on NaOH-P: inorganic fertilizer+organic +microbial fertilizer > inorganic fertilizer+organic > inorganic fertilizer + microbial fertilizer > inorganic fertilizer+organic+matrix > inorganic fertilizer > CK.Compared with CK,in the treatment of inorganic fertilizer+organic + microbial,(H2O-P+NaHCO3-P) improved 149.6% and NaOH-P 73.3% respectively.
