北京野鸭湖湿地土壤生物可利用磷的研究
Study on Bioavailable Phosphorus in Soils of Beijing Yeyahu Wetland
摘要
Abstract
[Objective] The research aimed to evaluate phosphorus nonavailability of soils in Beijing Yeyahu Wetland. [Method] Layer aoif samples were collected by columnar sampler. The contents of bioavailable phosphorus and total phosphorus in soils were measured, and the correlations between them were sutdied separately. [Result] The contents of BAP were in a low level which accounted 0.10% -8. 66% of TP in soils. The sequence of the contents of the four kinds of BAP was as follows: AAP > Olsen-P > WSP > RDP. The contents of AAP and Olsen-P in the soils decreased exponentially with the increase of the soil depth increased. [Conclusion] AAP and Olsen-P could be usi-d to evaluate the ability of soil phosphorus release potential for that the contents of them and the content of TP showed significant correlation.关键词
