Abstract:
Two peaks were present in the NRA annual curve of Panax quinquefolius. A high peak appeared in late April and a smaller peak occured in early July. It is important to apply N2 fertilizers just before the appearance of the two peaks. Experiment on the effect of different light and pH showed that higher NRA were formed at 4000 Lx and pH 4.3～6.0.
