[Study on dynamic growth of Codonopsis pilosula].

OBJECTIVE

To study on the dynamic changes of Codnopsis pilosula for the guidance of the field management.

METHOD

Using the random method the influences of the cultivating density and fertilizing weight at four different levels was observed.

RESULT AND CONCLUSION

The dynamic changes of the biomass, growth period andbiological changes at different growth stages were found out. The most predominant combination of the two factors, the 1.05 million roots/hm2 of the cultivating density and 240 kg x hm(-2) of the fertilizing weight reached the highest accumulation of stems & leaves; 652 mg x d(-1) the 0.6 million roots/hm2 and 240 kg x hm(-2) reached the heaviest single fresh root. The results could be used for the cultivating, fertilizing and practicing SOP of C. pilosula.
