Prevent deformed mushrooms early, cultivation of edible fungi must be taken seriously

Deformed mushrooms: when ventilation is poor and the carbon dioxide content in the mushroom room exceeds 0.3%, deformed mushrooms easily appear. If the fruiting position is too deep, mushrooms growing in the cracks of coarse soil also often become deformed. Key attention should be paid to ventilation and air exchange in the mushroom room.

Water-rust spotted mushrooms: if the mushroom room and the surface of the growing substrate are not ventilated and aired in time after watering, the mushroom room humidity is too high, small water droplets appear on the surface of the mushrooms, and over time rust-colored spots will form. Therefore, after each watering, doors and windows should be opened for 30 to 60 minutes for ventilation and air exchange.

Hollow-stem white-core mushrooms: too little watering, the casing soil layer is relatively dry, the fruiting bodies cannot get sufficient moisture, white pith appears in the mushroom stems, or they even become hollow. The main preventive measure is timely and appropriate watering; during the fruiting period, the relative air humidity in the mushroom room should remain above 85%.

Hard-opening mushrooms: a day-night temperature difference of 10°C, or an attack of strong cold air, can both cause mushrooms to hard-open. When the temperature changes suddenly, straw curtains should be added outside the mushroom room to keep the temperature in the mushroom room stable and the humidity suitable.

Thin-capped early-opening mushrooms: if the fruiting density is too high, the temperature is on the high side, or the humidity is on the low side, the fruiting bodies grow quickly with thin stems and thin caps, and will open early. Paying attention to maintaining suitable temperature and humidity in the mushroom room can effectively prevent the appearance of thin-capped early-opening mushrooms.
