摘　　要：通过比较大别山区不同海拔和林分类型的林下栽培西洋参地上和地下部位生长量的差异,分析大别山区林地环境对西洋参生长的影响。结果表明:海拔、林分类型和落叶层厚度均对林下西洋参的生长有显著影响,海拔1250~1300 m的针阔混交林的林地环境更适合高山林下西洋参生长,一定厚度的落叶层有助于西洋参根部的生长。The effect of the forestland environment on the growth of P.quinquefolium was analyzed by comparing the difference in the growth of the above-ground and underground parts of P.quinquefolium cultivated under different altitudes and stand types in the Dabie Mountains.The results showed that altitude,stand type and thickness of leaf litter all had significant effects on the growth of P.quinquefolium.The forestland environment of the coniferous and broad-leaf forest at an altitude oF_(1)250-1300 m was more suitable for the growth of P.quinquefolium,and a certain thickness of leaf litter was conducive to the growth of P.quinquefolium roots.
