title: [Study on seedling quality of Psoralea corylifolia and influence factors].
abstract: OBJECTIVE
  To study the effects of different fertilization, measure of breeding seedling, breeding and sowing density on seedlings of Psoralea corylifolia.
  
  
  METHODS
  The combination of field sowing and indoor test was applied.
  
  
  RESULTS
  All agricultural measures showed positive effect on the growth and development of seedling of P. corylifolia.
  
  
  CONCLUSIONS
  The suitable sewing time should be the first and second ten days in March. The suitable sowing density is 150 kg x hm(-2). The combined of application of organic manure and chemical fertilizer is better than using one of them alone.
