黄背木耳在我国栽培比较广泛，有段木栽培和袋料 栽培两种方法，袋料栽培出耳快，生长周期短，还可节省 大量的林木资源，因此近年来发展很快。我们根据当地 的气候特点和资源状况，通过几年的探索，总结出适合 于北方生产的大袋立体高产新模式。所谓大袋，是用折 径２２～２５ Yellow dwarf fungus is widely cultivated in our country, there are two methods of cultivation and bags of wood cultivation methods, bags of ear cultivation fast, short growth cycle, but also save a lot of forest resources, so the rapid development in recent years. Based on the local climatic characteristics and resources, we have summed up a new mode of three-dimensional and three-dimensional yield suitable for northern production through several years of exploration. The so-called big bag, is the use of folding diameter 22 ~ 25
