In this paper, the effects of multifunctional composite on soil physical properties were investigated through simulated the tree planting method as much as possible. The results showed that multifunctional composite can decreased soil pH and bulk density, increased the contents of total porosity, and improved soil cation exchange capacity. Soil >0.25mm aggregates were increased with increasing of concentration of multifunction composite. When using super absorbent with the dose of 50g, the >0.25mm aggregates proportion was increased in 8.91%~12.50% compared with control.
