Abstract： [Purpose]By establishing intercropping systems of different tree species with Panax notoginseng， the effects of forest-medicine intercropping on the growth characteristics and quality of

P⋅ notoginseng were evaluated， providing theoretical basis and technical support for the expansion of P notoginseng ecological planting mode and its high-quality. [Methods] Using P notoginseng monoculture as the control， intercropping systems with six tree species were set as the treatment groups. The effects on accumulation biomass and uptake of nutrients in P . notoginseng were explored， and the regulatory effect of the intercropping system on the morphology of P .notoginseng roots and the accumulation of medicinal component were analyzed. [Results] Compared with P notoginseng monoculture， intercropping with Eucalyptus robusta， Cunninghamia lanceolata， Platycladus orientalis，and Schima wallichii significantly increased the yield per unit area of P notoginseng by 69.29% ， 86.04% ， 114.65% and 54.58% ，respectively （P<0.05） . These systems also enhanced the absorption of nitrogen （N） ，phosphorus （P）， and potassium （K） （P<0.05） . Specifically， total content per unit area significantly increased by 149.68% 153.76% ， 201.75% ，and 141.10% ，respectively; total P content per unit area significantly increased by 55.76% ， 180.36% ， 66.78% ， and 81.69% ，respectively;and total K content per unit area significantly increased by 89.47% ， 86.27% ， 123.02% ，and 85.66% ，respectively. Compared to monoculture， intercropping with C lanceolata， P orientalis， and S. wallichii significantly increased nutrient （N， P，and K） uptake rates and saponin content （P<0.05） ： Furthermore， intercropping with C lanceolata and P ，orientalis promoted root length， root surface area， and root volume of P . notoginseng. [Conclusion] Intercropping P . notoginseng with coniferous species， such as C .lanceolata and P orientalis， improves its growth and medicinal quality. Therefore，utilizing the understory environment of coniferous forests for ecological cultivation is a viable strategy for high-quality medicinal plant production.
