关于白浆化淋溶土的磷素特性及其对植物磷素吸收的影响的研究还很有限。从东北四个地区的农田中采集了12种不同肥力水平的白浆化淋溶土。分析了土壤磷素形态、磷素吸附和供磷能力，并与土壤肥力和植物磷素营养进行了相关分析。土壤全磷含量为0.62- 0.91g·kg ~（-1），有机态磷占37-51%，无机态磷占49-63%，其中以吸持态磷含量最高，其次为Fe-P、Ca-P、Al-P，松散态磷含量最低。
The information on phosphorus (P) characteristics of albic luvisols and their effect on plant P uptake is limited. Twelve soils representing typical albic luvisols were collected from farmland of four regions in northeast China, each with various levels of soil fertility. Phosphorus fractions, P adsorption and P supply capacity of the soils were analysed and were correlated with soil fertility and plant P nutrition. Total P in these soils ranged from 0.62-0.91 g kg(-1), and comprised 37-51% organic P, and 49-63% in inorganic forms among which the percentage of occluded P was the greatest, followed by Fe-P, Ca-P, Al-P and loosely bound P was the lowest (
