The effect of phosphorus(P) and potassium(K) on plant growth and development was irreplaceable. Based on random sampling of several plant species in the west campus of University of Jinan, the concentration of leaf P and K were measured by the total nitrogen total phosphorus total potassium analyzer. The results showed that Armeniaca vulgaris Lam. has the highest concentration of P and K, reaching 395.08 mg/kg and 227.45 mg/kg, followed by locust Robinia pseudoacacia Linn.. Ailanthus altissima (Mill.) Swingle and Ligustrum quihoui Carr. has the lowest concentration of leaf P. The leaf P concentration of all plant species was higher than leaf K concentration except for skunk. Based on the soil nutrients status of study area, it was found that Armeniaca vulgaris Lam.and Robinia pseudoacacia Linn. could be appropriately expanded in the end.
