title: [Study on effects of seed stock, cultivating density on the yields and volatile oil of Curcuma wenyujin].
abstract: OBJECTIVE
  According to the study on effects of cultivating density and seed stock on the yield and volatile oil, to provide a scientific basis for standardized cultivating measures.
  
  
  METHODS
  The yield and the content of volatile oil at harvest were counted and analyzed the variance by SPSS.
  
  
  RESULTS
  The effect of cultivating density on the yields from 3 different medicinal parts of medical material was significant. The effect of seed stock on the yield of Rhizoma wenyujin concisa and Rhizoma wenyujin curcumae was significant, but to the yield of Radix wenyujin curcumae was very little. The mutual effect between cultivating density and seed stock was also very little.
  
  
  CONCLUSIONS
  The cultivating density play an important role in the yields of Curcuma wenyujin.
