OBJECTIVE
To preliminarily study the effect of fertilizer methods on the yield and quality of Fritillaria ussuriensis.
METHODS
Through the investigation of the available nitrogen, phosphorus, potassium in soil fertility of F. ussuriensis planting field as well as the measurement of total nitrogen, phosphorus, potassium contents in bulbus of F. ussuriensis, the balanced fertilization plan for cultivation of F. ussuriensis was made.
RESULTS
The optimal fertilizing amount was 13.0 kg x m(-2) pig dung, or 5.5 kg x m(-2) deer dung and 6.5 kg x m(-2) pig dung, or 11.0 kg x m(-2) deer dung.
CONCLUSIONS
Effective fertilizing may increase significantly the yield and quality of F. ussuriensis.
