摘  要:
通过棕壤定位试验,研究长期不同施肥后,棕壤微生物量磷的变化及其与土壤理化性质和微生物数量的关系。结果表明,长期施用化学磷肥或有机肥均能增加土壤微生物磷含量,尤以有机肥的作用明显;土壤微生物量磷含量较对照提高2.55~6.27倍,单施氮肥较对照下降42.8%,土壤微生物量磷与土壤肥力指标(除全钾、速效钾外)呈显著相关性,与微生物数量关系密切。

摘  要:
The changes of microbial phosphorus content in microorganism in brown soil and its correlation with physical and chemical properties of soil and microorganism amount were studied after long-term located experiment in brown soil with different fertilization for 27 years.The results showed that phosphate fertilizer and organic fertilizer in long-term application could increase microbial phosphorus content in soil,and the effect of organic fertilizer was significant specially.Compared with that in CK,the microbial phosphorus content in soil enhanced by 2.55~6.27 times and the nitrogen fertilizer applied separately decreased by 42.8%.The soil microbial phosphorus content was significantly related with the soil fertility index except total and rapid-available potassium and closely related with the microbial amount.
