title: [Studies on cultivation measures of Angelica dahurica].
abstract: OBJECTIVE
  To evaluate the effect of seedingtime, density of crop and fertilization on the yield of Angelica dahurica.
  
  
  METHODS
  Use weighing method to measure the output of A. dahurica.
  
  
  RESULTS
  The highest yield of seeding-time is 8373 kg/hm' on April 20, which is considerably different compared with April 5 and May 5; the highest yield of the density is 9300 kg/hm2 on 330,000 plants/hm2; the yield of fertilization tests all are considerable higher than that of the contrast.
  
  
  CONCLUSIONS
  The appropriate seeingtime of A. dahurica is the first or second ten days of April, the appropriate density is 330,000 plants/hm2, and the appropriate amount of fertilization is N24P20, i.e pure N 360 kg and P20, 300 kg per hectare.
