The article demonstrates the results of the research on the interaction between Platycladus orientalis and Robinia pseudoacacia to increase the growth and productivity of oriental arborvitae. The internal mechanism of the mixed growth gain of A. orientalis and R. pseudoacacia was described in terms of population structure, canopy morphology, microclimate of the forest, root system characteristics, nitrogen fixation of black locust and soil comprehensive fertility.
