天麻生长离不开蜜环菌,而人工培育蜜环菌种多采用木屑或枝条固体培养基,因培育蜜环菌培养基含水量要求在80％以上,因此在灭菌、接种或培养时稍不注意就会污染杂菌。几年来,本所试用半固体培养基培育蜜环菌取得了较好效果。具体方法:用1cm粗的枝条截成约3cm长的小段,装入菌种瓶,灌水浸没枝条(水中加入适量菌需营养料更佳),瓶口包扎塑料膜, Gastrodia can not be inseparable from the growth of Armillaria mellea, artificial cultivation of Armillaria species often use sawdust or solid wood shoots, because the culture of Armillaria mephitis medium moisture content of more than 80%, so in sterilization, vaccination or culture slightly Do not pay attention to pollution of bacteria. Over the past few years, the trial of semi-solid medium to cultivate Armillaria bacteria achieved good results. Specific methods: 1cm thick branches cut into small pieces of about 3cm long, into the bacteria bottles, irrigation immersed branches (water to add appropriate amount of bacteria to be better nutrition), bottle plastic wrap bandages,
