不同菌材对天麻(Gastrodia elata)产量的影响

Effects of Different Woods on the Yield of Gastrodia elata

  • 摘要: 以速生树种亮叶桦(Betula luminifera Winkler)和响叶杨(Populus adenopoda Maxim)、经济树种核桃(Juglans regia Linn)为菌材,壳斗科菌材白栎(Quercus fabri Hance)为对照,分别设置不同的菌材用量和麻种用量水平,仿野生栽培红杆天麻(Gastrodia elata Bl.f.elat)和乌杆天麻(Gastrodia elata Bl.f.glauca S.Chow),分析不同菌材对天麻产量的影响,筛选出高产的菌材种类、用量和天麻变型及麻种用量的组合,探讨亮叶桦、响叶杨和核桃代替壳斗科植物栽培天麻的可行性。结果表明:不同菌材对红杆天麻和乌杆天麻产量的影响有差异。两种天麻变型对菌材的偏好不同,红杆天麻在白栎和亮叶桦菌材处理下的平均产量高于响叶杨和核桃菌材处理下的产量,而乌杆天麻在亮叶桦和核桃菌材处理下的产量高于响叶杨和白栎菌材处理下的产量。两种天麻变型的最高产量的组合均出现在亮叶桦菌材伴栽的处理中。响叶杨伴栽天麻,效果不及亮叶桦和核桃。4种菌材对天麻的折干率影响不明显。在实际生产中,以亮叶桦、核桃和响叶杨作为替代菌材是完全可行的。从72个处理中筛选出高产的组合,单位面积菌材和麻种用量分别如下:12 kg亮叶桦菌材搭配0.8 kg红杆天麻麻种,12 kg核桃菌材搭配0.6 kg红杆天麻麻种,14 kg响叶杨菌材搭配0.8 kg红杆天麻麻种;14 kg亮叶桦菌材搭配0.6 kg乌杆天麻麻种,12 kg亮叶桦菌材搭配0.6 kg乌杆天麻麻种,10 kg核桃菌材搭配0.8 kg乌杆天麻麻种。

     

    Abstract: In our present study,the woods of Betula luminifera Winkler,Populus adenopoda Maxim,and Juglans regia Linn were used to culture Gastrodia elata Bl.instead of the traditional wood,Quercus fabri Hance.Four woods and three dosage levels were paired up with two Gastrodia elata forms with three immature tuber dosage levels to explore the best technology of cultivation of Gastrodia elata.Our results showed that the effect of different woods on the yield of G.elata Bl.f.elata and G.elata Bl.f.glauca S.Chow.were different.The yield of G.elata Bl.f.elata was higher than G.elata Bl.f.glauca on condition that they were planted with their four woody species.The highest yield treatments of the two Gastrodia elata forms both presented in Betula luminifera.The yield on Populus adenopoda and Juglans regia treatments were acceptable.For artificial cultivation of Gastrodia elata,the woody species of Betula luminifera,Populus adenopoda,and Juglans regia could be used instead of Fagaceae completely.The high-yield treatments screened from all 72 treatments can be referred in practical production(woody and immature tuber dosage per square meter):12 kg of Betula luminifera wood associated with 0.8 kg immature tuber of G.elata Bl.f.elata;12 kg of Juglans regia wood associated with 0.6 kg of G.elata Bl.f.elata immature tuber;14 kg of Populus adenopoda wood associated with 0.8 kg of G.elata Bl.f.elata immature tuber;14 kg of Betula luminifera wood associated with 0.6 kg of G.elata Bl.f.glauca immature tuber;12 kg of Betula luminifera wood associated with 0.6 kg of G.elata Bl.f.glauca immature tuber;10 kg of Juglans regia wood associated with 0.8 kg of G.elata Bl.f.glauca immature tuber.
