Abstract：The fractions and percentages of inorganic P,organic P and OlsenP in vegetable soils under plastic greenhouse and solar greenhouse conditions were analysed in suburban district of Beijing. The results indicated that the enrichment of phosphorus in the vegetable soils was rapid under the level of fertilization in Beijing. The average of OlsenP in 0-20 cm soil layer was 95-211 mgkg-1,and most of the phosphorus was accumulated in the top soil. The concentration of soil total P,organic matter and OlsenP had a r...
