Abstract: The research aimed to provide a scientific basis of arbor-shrub-herb compound vegetation construction in Pinus tabulaeformis Carr forest through studying the potential allelopathic effect of Pinus tabulaeformis rhizosphere soil. The potential allelopathic effects of Pinus tabulaeformis rhizosphere soil on germination and growth were investigated with 7 plants (Pinus tabulaeformis, Robinia pseudoacacia Linn., Platycladus orientalis, Lespedeza bicolor Turcz, Spiraea salicifolia L., Agropyron cristatum Gaertn, Medicago sativa L.), and with different concentrations (0.5, 1, 3, 5, 7, 10 mg/mL). The results showed that: Pinus tabulaeformis rhizosphere soil aqueous extract inhibited the growth of Robinia pseudoacacia Linn, Medicago sativa L., and stimulated the growth of Platycladus orientalis at each study concentrations. Low concentration of Pinus tabulaeformis rhizosphere soil aqueous extract promoted effect on Pinus tabulaeformis, Lespedeza bicolor Turcz, Agropyron cristatum Gaertn and Spiraea salicifolia L. At high aqueous extract, the stimulating effects changed into inhibited. As a result, when arbor-shrub-herb compound vegetation in pine forest is constructed, people should give priority to Platycladus orientalis, carefully choose Robinia pseudoacacia Linn and Medicago sativa L.. When people choose Lespedeza bicolor Turcz, Spiraea salicifolia L. and Agropyron cristatum Gaertn, pine forest intermediate cutting and intercropping density should be noted.
