在木耳、香菇根木栽培产区，绿色木霉、朱红栓菌、云芝、鸡毛菌等杂菌的危害相当严重。这些杂菌一旦侵入椴木，就与木耳、香菇争夺养料、水分和空间，甚至分泌一些毒素抑制菌丝生长，使菌丝萎缩死亡，影响出耳出菇。据调查，造成木耳或香菇减产通常达20％～60％，有的甚至毫无 In the fungus, mushroom cultivation of woody root zone, Trichoderma viride, Trametes versicolor, Coriolus versicolor, fecal fungi and other bacteria is very serious. Once the invasion of these bacteria basswood, with fungus, mushrooms for nourishment, moisture and space, and even the secretion of toxins inhibit mycelial growth, the mycelium atrophy death, affecting the ear fruiting. According to the survey, the loss of fungus or mushrooms is usually 20% to 60%, and some are even nonexistent
