Causes and Prevention of Mushroom malformation

In mushroom cultivation, the following abnormal mushrooms are produced in a high proportion, and the causes and preventive measures are as follows:

Because the ventilation rate of the mushroom is too large, the temperature is too low, the covering of fine soil is too late and the fine soil is too wet, the position of the solid primordium is too low, and the primordium is squeezed by the surrounding soil particles in the process of growth. the shape of the mushroom is not round, and the soil on the surface of the mushroom is like a landmine.

During the period of mushroom emergence, the air humidity of the mushroom is too low, the water of the mushroom body evaporates quickly, and the soil surface sprays less water, and the fast-growing fruiting body can not get the replenishment of water, so it will produce white pith or even hollow mushroom in the mushroom stalk.

Prevention methods in the peak period of mushrooms, it is necessary to strengthen water management, timely spraying water to prevent the soil layer from being too dry, so that the fast-growing fruiting bodies can get sufficient water, so as to reduce the occurrence of hollow mushrooms.

Before the spherical mushroom is covered with coarse soil, the old mushroom mass is not dug out, the thickness of the material layer is uneven, and the dry and wet surface of the bacteria bed is uneven, which will make several or more than a dozen fruiting bodies grow together in clusters, forming spherical mushroom bodies of different sizes. When picking large mushrooms, small mushrooms are implicated and damaged, ball mushrooms are crowded into clumps, and the finished mushrooms will be reduced.

Before sowing or hole sowing, the old fungus should be dug out in time or the thickness of the soil layer should be increased properly and the soil should be covered smoothly.

The temperature of umbrella mushroom suddenly drops, the humidity of fine soil is on the high side and the temperature of mushroom room is low, and the cold wind blows into the mushroom room at night to produce a large temperature difference, which will cause the immature young mushroom to break away from the stalk and cause the young mushroom to open the umbrella earlier.

Prevent the cold wind from blowing into the mushroom room suddenly, pay attention to the heat preservation, and keep the bacteria bed suitable water content, the young mushrooms can grow healthily at low temperature.

Pleurotus ostreatus due to thin soil cover, mycelium over fine soil, intermittent water supply, abnormal mushroom production, will result in dense and many mushrooms, resulting in light mushrooms and poor quality.

The prevention method is to apply fertilizer, add soil cover in time, spray water frequently and maintain normal humidity.

The culture material of Pleurotus ostreatus is insufficient fermentation, too thin, too dry, not enough water content in coarse soil, high mushroom density, sudden low and high humidity, fast fruiting body growth and early ripening, which can make the mushroom body stalk thin and thin.

To prevent the method, the culture material should be moderately mature, the material layer should be laid with a certain thickness and should not be too dry, and pay attention to control the rhythm of mushroom production.

After each spray of water, the mushroom room should be properly ventilated to release the moisture from the surface of the mushroom body.

The mushroom bed is too thick, the coarse soil particles are too large, the soil covering time is too late, the soil layer is too dry for a long time, the concentration of carbon monoxide caused by heating coal in winter is too high, and the pesticide is slightly damaged, all of which will result in mushroom body with long handle or small thick cover.

Prevention methods: soil particles should not be too large and too hard, do not cover soil too late, adjust moisture in time during mushroom production, prohibit the use of pesticides and properly ventilate.

The natural temperature of Pleurotus ostreatus is on the high side, and the material surface is sprayed too much water, especially before picking mushrooms, the water spraying is too heavy and the ventilation is poor, which often makes the mushroom feet red.

The prevention method should not contain too much water in the soil layer during the mushroom period, stop spraying water and adjust ventilation before picking.

The temperature of Pleurotus ostreatus is on the low side, the mushroom is dry, and the air temperature and dry humidity change rapidly, which is easy to make the cover produce scales.

Before the mushroom is produced, the relative humidity of the mushroom room should be increased and the balance should be kept as far as possible.
