| 摘 要： | 利用中国科学院海伦农业生态实验站的长期定位试验,研究了长期不同施肥条件下[对照(CK)、施用化学氮磷肥(NP)、化学氮磷肥配施有机肥(NP+OM)]农田黑土不同粒径水稳性团聚体中磷的分布及其有效性。结果表明,施肥增加了黑土各粒级水稳性团聚体中全磷含量,其中,NP处理比对照(CK)全磷含量增加28.9%~37.8%,NP+OM处理比NP处理增加44.0%~63.9%。施肥增加了黑土各粒级水稳性团聚体中有效磷含量,NP处理比CK处理有效磷含量增加146%~183%,NP+OM处理有效磷含量是NP处理的3.4~5.3倍。各处理水稳性团聚体全磷和有效磷均表现为较均匀地分布在0.053mm的各粒级水稳性团聚体中,而0.053mm粒级水稳性团聚体内全磷和有效磷均显著降低。施磷可显著增加土壤磷的有效率,且以化肥配施有机肥处理表现更为明显。NP处理不同粒径水稳性团聚体中磷的有效率是CK处理的1.94~2.32倍,NP+OM处理是NP处理的2.13~2.83倍。 |

| Abstract: | The distribution and availability of P in black soil water-stable aggregates were studied in a long-term fertilization field experiment. The field is located at Hailun Station of Agro-ecology Research, Chinese Academy of Sciences. The experiment included a control with no fertilization (CK), treatments with only chemical (N and P) fertilization (NP) and with chemical and pig manure (NP+OM) fertilization. The results show that fertilization increases total P content in the soil water-stable aggregates. Total... |
