[Ecological technique of cultivating Coptis chinensis in woods and co-cultivating it with maize].

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).

Conclusion: 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.
