What are the control methods for deformed mushrooms?
Deformed mushrooms
This mainly occurs when ventilation is poor and the carbon dioxide content in the mushroom house exceeds 0.3%, making deformed mushrooms likely to appear. Mushrooms that emerge too deep, growing out of cracks in the coarse soil, are also often deformed. For preventive measures, focus on ventilation and air exchange in the mushroom house.
Ground bud mushrooms
When the compost is brought into the mushroom house with excessive moisture, when the mushroom house is ventilated too long during watering of the coarse soil, when the fine soil is covered too late, or when the temperature is relatively low, ground bud mushrooms are likely to appear. For preventive measures, master proper watering amounts and timely ventilation so that the mycelium hangs above the clay and below the fine soil.
Red root mushrooms
Slightly acidic cultivation material, too much field water during the high-temperature stage before fruiting, excessive water content in the casing soil layer, excessive supplemental glucose, and poor ventilation in the mushroom house can all easily lead to red root mushrooms. For preventive measures, adjust the pH of the compost properly, keep the casing soil water content at 22%-25%, avoid sprinkling water at high temperatures, and keep the concentration of supplemental fertilizer appropriate.
Water rust spot mushrooms
If the mushroom house and the surface of the compost are not ventilated and aired in time after spraying water, the humidity in the mushroom house becomes too high, small water droplets appear on the surface of the mushrooms, and over time rust-colored spots form. For preventive measures, open the doors and windows for 30-60 minutes for ventilation and air exchange after each watering.
Hollow root white core mushrooms
If too little water is sprayed, the casing soil layer is relatively dry, and the fruiting bodies cannot get enough water, the mushroom stems develop a white pith, or even become hollow. For preventive measures, mainly spray water at the right time and in the right amount, and keep the relative air humidity in the mushroom house above 85% during the fruiting period.
Hard veil-opening mushrooms
A day-night temperature difference of 10°C, or a strong cold air outbreak, can both cause hard veil-opening in mushrooms. For preventive measures, when the temperature changes suddenly, straw curtains should be added outside the mushroom house to keep the temperature in the mushroom house stable and the humidity suitable.
Thin-skinned early veil-opening mushrooms
If the fruiting density is too high, the temperature is relatively high, or the humidity is relatively low, the fruiting bodies grow quickly with thin stems and thin caps, and the veils open early. For preventive measures, pay attention to maintaining suitable temperature and humidity in the mushroom house, which can effectively prevent the appearance of thin-skinned early veil-opening mushrooms.
