title: [Study on the characteristic of assimilating nitrogenous phosphorous fertilizer and the accumulation disciplinarian of total tanshinons of Salvia miltiorrhiza].
abstract: OBJECTIVE
  To confirm the amount of fertilizer and the ration of fertilizer.
  
  
  METHODS
  Through the experiment of planting Salvia miltiorrhiza in pot and in field were carried out.
  
  
  RESULTS
  When N:P = 1:1, The production was 1.8 times more than the contrast group in plotting experiment, and in field the production of the highest fertilizer plot were 2.5 times more than the contrast and the higher and high fertilizer plot is 2.25 and 1.2 times respective were than those in the contrast group.
  
  
  CONCLUSIONS
  The proper ration of nitrogenous fertilizer and phosphorous fertilizer is 1:1. Nitrogen shows negative effects to the accumulation of tanshinon IIA, the more the nitrogen ous fertilizer, The less the content of tanshinon IIA. In contrast, phosphor ous fertilizer shows good effects on the accumulation of tanshinon IIA. Phosphorous fertilizer could alleviate the decline of the content of tanshinon IIA by using nitrogenous fertilizer. The accumulation peak of the tanshinon IIA emerge in the period of 150 d.
