The research of soil P availability in Elaeagnus. mollis rhizosphere

In this paper, Total P, Inorganic P, Organic P, Available P and Soil pH in rhizosphere and non-rhizosphere soil of Elaeagnus.mollis were calculated and analyzed by soil P analysis methods. The results show that in Elaeagnus.mollis soil the Total P concentration in rhizosphere was similar to non-rhizosphere. Available P and Inorganic P concentration in rhizosphere were a bit higher than that in non-rhizosphere. Organic P concentration in rhizosphere were a bit lower than that in non-rhizosphere. But there was no significant difference. The correlation between each ingredient of Inorganic P and available P was compared, and found that the relative coefficients of both rhizosphere and non-rhizosphere did not get a significant level. Except Fe-P, the other ingredient concentrations in rhizosphere were little higher than that in non-rhizosphere. The pH in the soil of Elaeaqnus.mollis was smaller in rhizosphere than that in non-rhizosphere, and both of them were somewhat alkali. That is indentical with the high content of Ca-P.
