据我们1984年10月对陕西某种植区的调查访问,人工种植黑木耳,产量上不去的原因有三:1.流耳;2.死耳;3.耳棒上生长杂菌。据基层技术人员多年观察认为:耳棒上生长杂菌是黑木耳不能高产的主要原因,经我们鉴定,耳棒上杂菌近一二十种,消耗菌棒大量营养,加速木材腐烂,有的种类如环纹炭团,子座互相连成一片,使树皮下的形成层变黑,吸不到水分,黑面成为铁心而不能结耳。还有的种类,如红栓菌由接菌孔长出,也造成不结耳的后果。因此正确鉴定杂
According to our survey of some kinds of planting areas in Shaanxi Province in October 1984, artificial cultivation of black fungus, the yield does not go up for three reasons: 1. Earless ears; 2. Dead ears; According to grass-roots technical staff for many years that the observation: the growth of bacteria on the ear sticks is the main reason for the black fungus can not be high yield, identified by us, the ear sticks on nearly a dozen bacteria, consumption of a large number of bacteria stick bacteria, accelerate wood decay, and some Types such as ring carbon group, sub-base connected to each other, so that the formation of the bark under the dark, unable to absorb moisture, black noodles become the core and can not knot. Some species, such as red caterpillar fungus bacteria from the hole grow, also contributed to the consequences of non-stop ears. Therefore, the correct identification of miscellaneous
