Abstract: Studies on the management model of Cunninghamia lanceolata-Citrltllus vulgaris show that interplanting C. vulgaris with continuously planted C. lanceolata can improve soil fertility,prevente water and soil erosion and promote seedling growth. The biomass and volume productivity of tested stands are respectively 141.85 and 191.22% highier thancheck,and hence,a sustained, fast-growing and high-yielding young forest can be established.
