A mixed afforestation experiment of Cunninghamia lanceolata and Phoebe bournei was conducted at the fringe of the C.lanceolata production area to analyze the growth performance of the mixed forest and its effects on soil properties.The results indicate that the mixed planting,with a 6∶4 ratio of C.lanceolata to P.bournei in a star-shaped pattern,exhibited significant advantages,including strong envi-ronmental adaptability and stress resistance.The mixed forest notably enhanced the growth of both species,significantly improving stand quality and productivity.Compared to pure C.lanceolata stands,the height,diameter at breast height(DBH),and individual tree volume of C.lanceolata in the mixed forest increased by 5.17%,7.25%,and 19.67%,respectively.Similarly,the height,DBH,and individual tree volume of P.bournei in the mixed forest increased by 3.75%,5.08%,and 12.98%,respectively,compared to pure P.bournei stands.Addi-tionally,the mixed afforestation improved soil quality,with enhancements observed in various soil physicochemical properties.
