摘要
Abstract
To research the effects of planting density on growth,yield and accumulation of secondary metabolites of Codonopsis pilosula,we conducted a single-factor randomized block experiment with 5 planting density treatments:20 cm×10 cm,20 cm×15 cm,20 cm×20 cm,30 cm×10 cm,30 cm×15 cm.The roots were harvested at three different times;30th August,30th September and 20th October.The root yield and secondary metabolite content were subject to statistical analysis.Planting density had a significant effect on growth,yield and secondary metabolite content;yield and secondary metabolite content were much higher in the 20 cm × 10-15 cm treatments.It was also observed that C.pilosula in Tanchang was still growing in late October,and that the quality of the extract conformed with the necessities of the China Pharmacopoeia.Consequently,late October is the suggested harvest period.关键词
