title: [Ecological technique of cultivating Coptis chinensis in woods and co-cultivating it with maize].
abstract: OBJECTIVE
  To establish ecologically new modes of cultivating Coptis chinensis in woods and co-cultivating it with maize.
  
  
  METHODS
  Based on the experience obtained from plot comparative test and production test, we used application-oriented research methods, and established new Coptis chinensis cultivation techniques that protect the natural environment.
  
  
  RESULTS
  Coptis chinensis was harvested 6 years after cultivation. Yield of Coptis chinensis cultivated in forest (69.5 kg per 0.067 hm2) was higher with 3.7% than that in controls which cultivated under shed (67 kg). Yield of Coptis chinensis co-cultivated together with maize (168.4 kg per 0.067 hm2) was lower with 15.8% than that in controls which cultivated under shed (200 kg).
  
  
  CONCLUSIONS
  The new cultivation modes of Coptis chinensis is an ecologically new technique that assures the good growth of medicinal plants, cereals, forest and animal husbandry.
