天麻节料高产栽培技术的研究

目的：研究天麻节料高产的栽培技术。方法：采用田间栽培法。结果；在天麻有性繁殖中，（1）用短菌枝代替菌材播种，两层菌枝，播种4层种子，可使天麻种子萌发后形成的原球茎接蜜环菌率达50％以上，播种半年后，白麻米麻的产量高；（2）长菌捧播种，两层菌捧，播种4层种子，可使产量翻倍。在天麻无性繁殖中，改用短菌棒伴栽天麻，不仅可以节约木材和种麻，还可保证天麻的产量。结论：新的栽培方法在节料的同时，不但可保证天麻的产量，而且使天麻高产。

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

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.
