黑木耳属中温性菌类，多在春末夏初温度达 20℃以上的条件下出耳，因此对水分的要求较高，相对湿度应维持 85％～ 90％。如果湿度太低，就影响原基形成和子实体发育。但浇水过多，又容易导致流耳和病害发生。实践证明，采用雾灌育耳，可获得稳产高产。现将有关技术介绍如下。 Auricularia are temperature-sensitive fungi, and more in the late spring and early summer temperature of 20 ℃ or more under the conditions of the ear, so the water requirements are higher, the relative humidity should be maintained at 85% to 90%. If the humidity is too low, it will affect the formation of primordia and the development of fruiting bodies. But too much water, but also easily lead to ear and disease. Practice has proved that the use of fog irrigation ears, can be stable and high yield. The technology is introduced below.
