我省有大量的地下人防工程和山洞,常年温湿度恒定,适宜发展食用菌栽培事业。自1984年以来,我们利用地下人防工程开展了以双孢蘑菇为主的大面积栽培试验,就拿我们在石家庄市利用的一段地下人防工程来说,洞内常年温度12～14℃,空气湿度90～95%,这样的条件有利于双孢蘑菇子实体生长发育,但菌丝生长最适温度23～25℃,洞内温度显然太低,如何提高料温,使之更有利于双孢蘑菇菌丝的生长,我们采用了地热线加温的方法,现将试验结果介绍如下:
My province has a large number of underground air defense projects and caves, perennial temperature and humidity is constant, suitable for the development of edible fungus cultivation. Since 1984, we have carried out a large-scale cultivation experiment mainly on Agaricus bisporus with underground civil air defense projects. Taking the underground civil air defense works that we used in Shijiazhuang City, the perennial temperature in the cave is 12-14 ℃ and the air humidity 90 ~ 95%, this condition is conducive to the growth of Agaricus bisporus fruiting body growth, but mycelial growth optimum temperature 23 ~ 25 ℃, the temperature is obviously too low inside the hole, how to improve the feed temperature, making it more conducive to Agaricus bisporus Mycelium growth, we use the geothermal heating method, the test results are as follows:
