摘　　要：为探讨滇重楼在贵州省毕节市大田遮荫栽培模式的合适种植密度,对比5种不同栽培密度下滇重楼农艺性状、光合特性、产量及品质的差异。试验结果表明,不同栽培密度对滇重楼农艺性状、光合特性的影响有一定差异,但差异不显著,对单位面积产量的影响则有显著性差异,滇重楼3种甾体皂苷总含量随栽培密度增大而降低,但均符合《中华人民共和国药典》的要求。从农艺性状、光合特性、产量及品质方面考虑,毕节市滇重楼栽培适宜株行距8.3 cm×20 cm或10 cm×20 cm,但考虑后期滇重楼根茎和地上植株生长还需要空间,建议优先选择株行距10 cm×20 cm,其皂苷总含量更高。To discuss appropriate cultivation density of Paris polyphylla Smith var.yunnanensis in shading cultivation mode in Bijie City,Guizhou Province,differences in agronomic traits,photosynthetic characteristics,yield,and quality of Paris polyphylla Smith var.yunnanensis under 5 cultivation densities were compared.Results showed that there were differences between agronomic traits and photo-synthetic characteristics of Paris polyphylla Smith var.yunnanensis with different cultivation densities,but differences were not signific-ant.Significant differences were found in yield per unit area.Total content of three steroidal saponins in Paris polyphylla Smith var.yunnanensis decreased as cultivation density increased.All results met requirements of Pharmacopoeia of the People's Republic of China.Considering agronomic traits,photosynthetic characteristics,yield,and quality,a recommended row spacing for Paris poly-phylla Smith var.yunnanensis cultivation in Bijie City was 8.3 cm×20 cm or 10 cm×20 cm.However,considering later stages of Par-is polyphylla Smith var.yunnanensis rhizomes and aboveground need more space,it was recommended to prioritize a row spacing of 10 cm×20 cm,which had a higher total content of steroidal saponins.
