Study on the change of accumulation and yield of dry matter in Chinese angelica shows that the fertilizer can not obviously promote the growth of leaf and stem but can make the amount of dry matter and yield increase,taking the different kinds of fertilizer and N P combination as the main facter.During the latter growing period(in sixteen December),the amount of dry matter increases by 6.1%～71.4% comparing with CK. Ammonium-nitrate’s effect is the best.It can make the amount of dry matter increase by 71.4% and be 25.2g/plant , and make the individual yield increase by 96.69% , up to 2200㎏/hm2 . the next are Phosphor two ammonium [(NH4)2HPO4] and the combination of urea and calcium superphosphate.The both amounts of dry matter are 16.0g/plant.They are higher than CK by 1.3g/plant.The combination of urea and calcium superphosphate can make the individual yield up to 1985.19㎏/hm2 , increase by 77.48% , comparing with CK.
