The formation of Pleurotus ostreatus is mainly due to high temperature, rapid growth of fruiting bodies, high planting density, and insufficient nutrient supply. The production of thin-shelled mushrooms is also related to the characteristics of the varieties. Most of the adventitious varieties are dense and easy to produce thin-skinned mushrooms, which have low yield and poor quality. Airborne varieties of culture materials and overlying soil cover, coupled with less water spray, resulting in inadequate nutrition and water supply, will also produce thin-skin mushroom. After the soil-concreting period, due to less water spray, more water sprays, less ventilation, and high air humidity in the mushroom house, the mycelial growth site is too high, the fruiting body is on the surface of the fine soil, and the foundation is shallow, and thin skin is also easily produced. mushroom. If proper ventilation during the water transfer period in the soil will make the mushrooming part between the coarse soil and the fine soil layer, the thin skin mushroom can be reduced. Appropriately increase the thickness of culture materials and soil layers, strengthen water management during fruiting period, and prevent the production of thin skin mushroom. Hollow mushrooms are mainly caused by improper water management during fruiting period. During the mushrooming period, the humidity of the air in the mushroom house is too low, the water in the mushroom body evaporates quickly, and the water sprayed on the soil surface is less, the soil layer is too dry, especially the coarse soil layer is too dry, and the rapidly growing fruit body is not supplemented with water. It will produce white loose pith in mushroom shank, and even produce hollow mushroom in stipe. If water management is strengthened during the affluent period, water is sprayed in a timely manner, and intermittent heavy water is sprayed appropriately, the soil layer will not be dried, and the coarse soil particles will also be able to obtain moisture and maintain a certain humidity, so that the rapidly growing fruit bodies can be obtained. Adequate moisture to prevent the production of hollow mushrooms.
