[Influence of humic acid fertilizer on biomass accumulation and quality of Angelica sinensis].
OBJECTIVE
To study the influence of humic acid fertilizer on plant growth, assimilation base, dried biomass accumulation, yield, quality and disease infection of Angelica sinensis.


METHODS
Three kinds of humic acid fertilizer and an amino acid liquid fertilizer were tested in randomized groups at 1 level with 3 times repeat.


RESULTS
T1 promoted plant and root growth effectively, increased dried biomass accumulation and fresh root average weight remarkably, the yield was increased, the content of ethanol extract was increased by 11.31%. T3 promoted plant and root growth quickly, enlarged leaves area and increased dried plant weight, but effect lasted shortly, the content of ethanol extract was increased by 5.23%. T4 increased more leaves in late growth period, enlarged leaves area, the yield was increased, the content of ethanol extract was increased by 3.09%. T2 increased fresh root average weight remarkably, the yield was increased.


CONCLUSIONS
Humic acid fertilizer and amino acid liquid fertilizer could effectively promote plant growth, enlarge leaves area, promote dried biomass accumulation and transformation to root and increase yield and content of ethanol extract effectively.
