通过对龙胆草种植密度及基肥的试验研究，分析二者对龙胆草地上部和地下部农艺性状的影响。结果表明，不同种植密度对龙胆草地上部性状株高、叶长和叶宽影响不大，各处理之间差异不显著，茎粗以20株／行处理最好，与15株／行之间差异达到显著水平。根部各性状随着种植密度的增加而增加，尤其对根长、根重和小区产量的影响达到显著水平，龙胆种植密度以25株／行和20株／行处理比较好，可促进植株生长，并能提高其产量；复合肥基肥试验中，除100g／m2处理外，各处理地上部株高、茎粗、叶长和叶宽值均高于对照，对植株生长起到促进作用；地下部各性状，除100g／m2处理外，各处理根长、根粗、须根数、根重和小区产量值均高于或显著高于对照，综合分析龙胆植株各生长性状和产量性状以75g／m2处理最好。

This study evaluated the effects of different density and base fertilizers on agronomic traits of Gentiana sca‐bra Bge .The result showed that plant density have no significantly affected on aerial part traits of Gentiana scabra Bge .The highest value of stem diameter were found in 20 plant per row treatment ,which were significantly higher than 15 plant per row treatment .Plant density have significantly affected on root length ,single root weight and plot yield ,and these values increased with an increase in plant density .The optimum plant density was 20 and 25 plant per row which could promote yield and aerial part growth .Base fertilizer could promote growth except 100g/m2 ,the value of plant heigh ,stem diameter ,leaf length and leaf width all higher than control .For root characters ,the value of root length ,single root weight ,the number of fibrous root and plot yield ,all higher than control except 100g/m2 treatment .Comprehensive analysis of agronomic traits ,the optimum applied amount of chemical fertilizer was 75g/m2 .
