银耳又叫白木耳,是我国最著名的一种胶质的药用菌和食用菌。它有很高的营养价值,也是贵重的中药材。在国际市场上享有很高声誉,每年大批出口,可换取大量的外汇。其栽培方法较简单,也是农村社队容易经营,且收益较大的一种好副业。但自古以来,银耳都是在天然场所,伐木堆积,段木栽培。这种栽培方法,十分古老,生产场所占地大,不易人工控制栽培,又消耗大量可贵的木材。近年来,由于对银耳进行生物学的探索和研究,使能在室内人工控制环境条件下,用瓶栽的新技术生产银耳。这样既可大大减少木材资源的消耗,而产量又可比段木栽培提高10～20倍。
White fungus, also known as white fungus, is China’s most famous gum a medicinal and edible mushrooms. It has a high nutritional value, but also expensive Chinese herbal medicines. Enjoy a high reputation in the international market, a large number of exports each year, in exchange for large amounts of foreign exchange. The cultivation method is simpler, and it is also a good sideline for the rural community to operate easily and make a big profit. However, since ancient times, white fungus are in natural places, logging accumulation, section of wood cultivation. This cultivation method is very ancient, the production site covers a large area, not easy to control artificial cultivation, but also consume a lot of valuable wood. In recent years, as a result of the biological exploration and research on Tremella, it has been possible to produce Tremella with the new bottle-planting technology under the conditions of artificial indoor control. This will not only greatly reduce the consumption of wood resources, but yield can be increased 10 to 20 times higher than the segment of wood.
