摘　　要：通过几种不同密度种植方式对太子参产量及活性成分的影响进行了研究。结果表明:太子参在一定程度上密度越大产量越高,但过密种植反而使产量有所下降;在一定程度上,太子参的水分含量随着种植密度的增大而降低;总体上,种植密度小的处理其灰分含量高,密度大的处理灰分含量低;多糖含量变化总体上种植密度越小含量越高;在株行距8 cm×15 cm和株行距12 cm×10 cm 2个栽植水平上,总皂苷含量最高,密度最大的株行距8 cm×10cm和密度较小的株行距16 cm×15 cm的栽植方式,总皂苷含量最低,株行距12 cm×10 cm栽植方式的总皂苷含量为16 cm×15 cm栽植方式的总皂苷含量的1.95倍,说明适宜的栽种密度有利于总皂苷的积累。为使太子参产量和活性成分达到最大,建议太子参的种植密度为8 cm×15 cm或12 cm×10 cm。The influence of 10 different planting densities on Pseudostellaria heterophylla＇s root yield and active substance content was dealed with. The results showed that,to a certain extent,the higher planting density was,the greater the yield was,but the yield decreased with too dense planting; As the density increased to a certain extent,water content decreased;Overall,higher ash content got with smaller planting density; In general,polysaccharide content increased with planting density decrease; Saponins content in the planting densities of 8 cm spacing in the rows × 10 cm line spacing and 16 cm spacing in the rows×15 cm line spacing got the lowest level while saponins in the densities of 8 cm spacing in the rows by15 cm line spacing and 12 cm spacing in the rows by 10 cm line spacing got the highest,presenting that the suitable planting density was in favor to saponins accumulation. In order to gain P. heterophylla＇s root yield and maximum active substance content,the planting densities of 8 cm by 15 cm or 12 cm by 10 cm were recommended.
