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%。
The modified Hedley phosphorus morphological grading method was used to study the effects of different fertilization treatments on phosphorus in soil. The results showed that fertilizers increased the content of various forms of phosphorus in soil, but different treatments increased in different ranges. Among them, the increasing range of active phosphorus (H 2 O-P + NaH-CO 3 -P) Fertilizer + organic fertilizer + microbial fertilizer> inorganic fertilizer + microbial fertilizer> inorganic fertilizer + organic fertilizer + matrix> inorganic fertilizer + organic fertilizer> inorganic fertilizer> CK, Fertilizer + organic fertilizer + microbial fertilizer> inorganic fertilizer + organic fertilizer> inorganic fertilizer + microbial fertilizer> inorganic fertilizer + organic fertilizer + matrix> inorganic fertilizer> CK. Inorganic manure + organic manure + manure treatment increased soil active and phosphorus by 149.6% and 73.3%, respectively, compared with the control.
