Why do mushrooms die in oyster mushroom cultivation? Explaining the causes
During cultivation, oyster mushrooms often die, mainly due to the following reasons:
Excessive temperature. The optimum temperature for oyster mushroom fruiting body growth is 6-28°C. Different varieties require different temperatures: high-temperature varieties have an optimum of 24-28°C, medium-temperature varieties have an optimum of 20-24°C, and low-temperature varieties have an optimum of 6-20°C. If the temperature is too high, a large number of small mushrooms will die.
Improper humidity. During the growth and development stage, oyster mushroom fruiting bodies require a relative air humidity of 80%-90%. If the relative air humidity is below 80%, the small mushrooms will wither and die due to massive evaporation of water from the fruiting bodies; if the relative air humidity is above 95%, the fruiting bodies absorb too much water, causing edema, which leads to infection by pathogens and death from rot.
Insufficient nutrients. In the early stage of fruiting, if the substrate surface produces too many mushrooms, some young primordia will die from insufficient nutrients. After two harvests of oyster mushrooms, the effective nutrients in the substrate are heavily depleted, so 0.1% urea, 0.3% sucrose, and 0.2%-0.3% phosphate fertilizer, etc., should be added along with water supplementation; otherwise, the primordia will die from nutrient deficiency.
Poor ventilation. Oyster mushrooms are aerobic mushrooms. During the growth stage of the fruiting bodies, if ventilation is poor, the carbon dioxide concentration is too high, and the oxygen concentration is too low, the small mushrooms will form deformed mushrooms or die due to lack of oxygen.
