title: [Study on the physicochemical properties of cultivated soil of genuine crude and no-enuine crude Chinese Angelica].
abstract: OBJECTIVE
  To provide basis for environmental factors of genuine crude Chinese angelica.
  
  
  METHODS
  On-the-spot investigation and indoor chemical analysis were made to study the physicochemical properties of cultivated soil of Chinese angelica.
  
  
  CONCLUSIONS
  The physical properties and the organic matte and mineral nutrition of cultivated soil of Chinese angelica are best in Min County, Gansu Province. The ecological environment is the leading factor in forming genuine crude Chinese angelica.
