title: [Study on biomass dynamic changes of Codnopsis pilosula under the planting density and fertilizing amount].
abstract: Study on the biomass dynamic changes of Codnopsis pilosula (Franch.) Naff. under the different planting density and fertilizing amount of the four levels respectively via the random methods have showed out: the best combination for the stems and leaves are 1.05 million plant/hm2 and 240 kg fertilizer/hm2. Its biomass accumulation can achieve 652 mg/d; That for the root are 0.6 million plant/hm2 and 240 kg fertilizer/hm2 and the weight of every fresh root achieved 14. 88g. The results will be helpful to cultivating and fertilizing of Codnopsis pilosula.
