ABSTRACT
OBJECTIVE:
To find out the effects of different levels and combinations of nitrogen, phosphorus and potassium on the growth and secondary metabolites of Scutellaria baicalensis.METHODS:
The quantities of growth, physiological indicators and baicalin contents in different fertilization treatment were calculated and compared.RESULTS:
The growth physiological indicators and baicalin contents of S. baicalensis in complex fertilization treatment were better than those in single element fertilization treatment, and nutrition balance types better than maladjustment type. The reasonebly fertilitzing in complex fertilization treatment, nitrogen could improve the fertilizer efficiency of phosphorus.CONCLUSION:
According to the fertilization mathematic model, the optimum fertilization dosage should be primarily defined as N 22.6-25.0 g/m2, P 30.6-44.6 g/m2, K 5.4-21.4 g/m2, that is 2N3P1K.
