摘　　要：为进一步推广黄花倒水莲林下栽培提供技术参考,该文选择对林分类型(竹林、针叶林及混交林)及海拔高度进行双因素试验设计。通过对林下套种黄花倒水莲的生长状况进行分析,结果表明:不同林分类型对黄花倒水莲的根鲜重及地径的差异不显著,而对株高的生长影响却达极显著水平;不同海拔高度对黄花倒水莲的株高及根鲜重生长的影响显著,且对地径的生长影响达极显著水平;林分类型及海拔高度二者的互作效应对黄花倒水莲的生长影响不显著。为了优化林下套种模式,综合各因素影响,宜选择在海拔高度为850 m(751～850 m)的混交林下进行黄花倒水莲套种。Forest types （bamboo forest, coniferous forest, mixed forest） and altiudes were designed for double-factor experiment, inorder to provide reference for expanding undergrowth cultiviation of P. fallax. The growth conditions of inter-planting with P. fallaxwere analysed, the results showed different forest type had no significant difference on root fresh weight and ground diameter of P.fallax, while had significant difference on plant height. Different altitude had significant difference on root fresh weight and plantheight of P. fallax, and had highly significant difference on ground diameter. The interaction effects between forest type andaltitude had no significant difference on P. fallax. In order to optimize the inetr-planting mode, the effect of various factors weredecided comprehensively. The mixed forest located at 850 m （751-850 m） should be chosen on inter-planting with P. fallax.
