Studies on cultivation of Gastrodia elata to lower expense and increase yield / 中草药

ABSTRACT

Object As stated in the subject. Methods By field cultivation.Results In sexual reproduction, (1) short tree branches can be used instead of the conventional tree trunks. Sow four layers of seed on to two timber layers. The peretration rate of Amillaria mellea (Vahl. ex Fr.) Karst into the germinated Gastrodia elata Bl.protocorm can attain well over 50%. After half year, the yield of both small and medium sized gastrodia tubers (2) Sow four layers of seed onto every two layers of long tree trunks may double the yield. In asexual propagation, the use of short tree branches not only can save timber material but also maintain the yield.Conclusion This new cultivation method can be used to save timber while maintaining the quality and quantity in the production of G. elata.
