How do you prevent deformed mushrooms when growing oyster mushrooms in winter? We ask fellow growers to share their guidanceWhen growing oyster mushrooms in winter, poor management can easily lead to various deformed mushrooms, reducing their commercial value; below is a detailed introduction to solutions for various oyster mushroom deformities (for reference).
1. Big-foot mushroom:
After primordia form, the cap differentiates and develops unevenly, showing only a growing stipe that is thick at the bottom and thin at the top, with no cap forming; the cap diameter is smaller than the stipe diameter, forming a big-foot deformity. The stipe of this mushroom is relatively hard, and its commercial value is low.
Solution:Ensure good ventilation and reasonable watering. Even during continuous low-temperature weather, during the fruiting period you should still use the warmer part of the day for short periods of ventilation and air exchange. Water frequently, but do not water too heavily at one time.
2. Blue mushroom:
During the mushroom's growth, a blue halo appears at the edge of the cap, and even the entire mushroom body turns blue-black, without fading until harvest.
Solution:For heating measures, sunlight, radiators, and electric heating are preferable. If burning wood or coal is used for heating, closed heat-transfer and smoke-exhaust pipes should be installed; it is not advisable to set up a stove directly in the mushroom house.
3. Tumor-cap mushroom:
Tumor-like or granular protrusions appear on the cap surface, called blistering or wrinkling in mushroom production, and the mushroom body shows slow growth. In severe cases, the cap becomes rigid and shrinks, and the mushroom body stops growing.
Solution:When cultivating oyster mushrooms in winter, you must clearly understand the minimum temperature that the normal growth and development of the mushroom body of the cultivated variety can tolerate, carry out good insulation and heating measures, and control the temperature of the mushroom bed.
When using variable-temperature stimulation measures, they should also be controlled within the suitable temperature range for mushroom body development, and the cooling process should not last too long. Generally, medium-temperature varieties should be controlled above 8°C, and low-temperature varieties should be controlled above 0°C.
