OBJECTIVETo preliminarily study the effect of fertilizer methods on the yield and quality of Fritillaria ussuriensis.
METHODThrough 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.
RESULTThe 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.
CONCLUSIONEffective fertilizing may increase significantly the yield and quality of F. ussuriensis.

OBJECTIVETo study the effect of different seminal rhizomes on the growth, quality and quantity of Curcuma longa root.
METHODSingle factor randomized block design was applied, plant samples were collected and investigated periodically, and dry weight, production and the main active ingredient content were measured.
RESULTThe difference seminal rhizomes affected the growth, quality and quantity of C. longa root.
CONCLUSIONThe bigger and stronger rhizomes should be chosen as seeds.
