Study on dynamic growth of Codonopsis pilosula / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study on the dynamic changes of Codnopsis pilosula for the guidance of the field management.</p><p><b>METHOD</b>Using the random method the influences of the cultivating density and fertilizing weight at four different levels was observed.</p><p><b>RESULT AND CONCLUSION</b>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.</p>
