摘　　要：在杉木边缘产区开展杉木与闽楠混交造林试验,分析混交林的生长状况及其对土壤理化性质的影响。结果表明,采用6杉木︰4闽楠的星状混交方式造林,混交优势明显,具有较强的环境适应性和抗逆性,且有效促进杉木与闽楠的生长,显著提升林分质量和产量。与杉木纯林相比,混交林中的杉木树高、胸径和单株材积分别提高5.17%、7.25%和19.67%;混交林中的闽楠树高、胸径、单株材积则分别较闽楠纯林提高3.75%、5.08%、12.98%。此外,混交造林还改善了林地土壤质量,土壤的理化性质均有不同程度的提升。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 environmental 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.Additionally,the mixed afforestation improved soil quality,with enhancements observed in various soil physicochemical properties.
