Coral-like mushrooms are caused by excessive concentrations of carbon dioxide in the mushroom room. In addition, coral-like mushrooms will also appear due to insufficient nutrients in the culture medium, and the high proportion of deformed mushrooms in the second tide mushroom is due to nutritional disorders. The prevention and control method is to strengthen ventilation during the mushroom emergence period, so that the concentration of indoor carbon dioxide is kept below 0.1%. After the first tide mushroom is collected, it is necessary to replenish the nutrient solution to the culture medium in time, such as 1% sucrose water, 0.1% compound fertilizer or rice water, which can effectively prevent the formation of coral mushrooms.
