Causes and preventive measures of hollow thin skin of Pleurotus ostreatus

In the cultivation process of Agaricus bisporus, some thin skin mushrooms and hollow mushrooms are often produced. The occurrence of this phenomenon not only reduces the varieties of Agaricus bisporus, but also seriously affects the economic benefits of mushroom farmers. So in the cultivation management must be careful, then how to prevent Agaricus bisporus hollow thin skin? Let's learn about it together with Xiaobian.

1. Reasons for hollow thin skin of Agaricus bisporus

1. High temperature

The production of Agaricus bisporus is mainly related to high temperature, which will cause rapid growth of fruit body, plus high cultivation density and insufficient nutrition supply.

2. Variety characteristics

In addition, the production of thin-skinned mushrooms is also related to the characteristics of varieties. Most of the adherent varieties have dense mushrooms, which are easy to produce thin-skinned mushrooms with low yield and poor quality; while the aerial varieties, the culture medium and the covering layer are too thin, and the water spray is less and light, resulting in insufficient nutrition and water supply, which will also produce thin-skinned mushrooms.

3. Improper spraying

During the period of water transfer after soil covering, because of light water spray, more water spray times, fast water transfer, and less ventilation in mushroom house, the air humidity in mushroom house will be higher, the mycelium growth position will be too high, the fruit body will grow directly on the surface of fine soil, and before the foundation, the thin skin mushroom will be produced.

4. Improper water management

The production of hollow mushroom of Agaricus bisporus is caused by improper water management during the mushroom production period. In the mushroom production period of Agaricus bisporus, if the air humidity is low, the moisture of the mushroom body evaporates quickly, and the soil surface is sprayed less, the water layer is too dry, and the fruit body will not get enough moisture for growth. At this time, the stalk will produce white loose pith, and even produce hollow mushroom.

II. Preventive measures

For the reason of hollow thin skin of Agaricus bisporus, preventive measures should be taken. The temperature should be controlled appropriately during the fruiting period, not too high or too low. The cultivation density should be paid attention to to ensure adequate nutrition supply. During the water transfer period, proper ventilation should be maintained, and the mushroom should be placed between the coarse soil and the fine soil layer, which can reduce the thin-skinned mushroom, and at the same time increase the thickness of the culture medium and the soil layer appropriately, strengthen the moisture during the mushroom production period, and also prevent the thin-skinned mushroom from being produced. During the fruiting period, water management should be strengthened, and heavy water should be sprayed at appropriate time, so as not to make the soil layer too dry, and at the same time, coarse soil particles can also obtain water, and certain humidity can be maintained, so that the fast-growing fruit bodies can obtain sufficient water and prevent the production of hollow mushrooms.

The above is an introduction to the reasons and preventive measures for the hollow thin skin of Agaricus bisporus. I hope to help you. If you want to know more about it, please pay attention to us.
