Pleurotus ostreatus in the cultivation process, often subject to temperature, air humidity, pests and diseases, mushroom house management conditions, etc., and the emergence of large areas of mushroom shrinkage, death phenomenon, seriously affecting the yield and yield of Pleurotus ostreatus. Experts suggest that in the fall, due to the large temperature difference between day and night, the temperature fluctuations are obvious, and it is easy to affect the cultivation of the oyster mushroom. Therefore, the oyster mushroom must be carefully managed at this time. One, a variety of causes induced death mushroom Variety, temperature, and humidity are all important factors affecting the yield of Pleurotus ostreatus. We must identify the cause of Pleurotus ostreatus inducing mushrooms and take timely measures to control and reduce losses. 1. Strains do not adapt to environmental conditions. There are many varieties of oyster mushrooms, which can be classified into high-temperature type, medium-high temperature type, and high-temperature wide type according to the type of temperature. To obtain high quality and high yield of oyster mushrooms, it is important to choose the correct variety. Such as rushing in the summer fruiting, when the temperature is higher, but the strains are low temperature or medium temperature type, then easy due to bacteria can not adapt to cause dead mushrooms. 2. The temperature fluctuates for a short time. In the early autumn, temperatures tend to fluctuate in the short term. External temperature rises to about 30°C, which is conducive to vegetative growth of Pleurotus ostreatus, and the reproductive growth of fruiting bodies is hindered. Bacterial cover will gradually wither and cause death of a large number of mushroom or mushroom buds. It is difficult for the mushroom to suddenly adapt to cool down, and it is easy to cause a large area of ​​death. 3. Strong winds cause a sudden drop in humidity. Pleurotus ostreatus in the cultivation if the ventilation is not conducive to wind, it will often lead to lower humidity within the mushroom shed, when the relative humidity of the shed is less than 80%, the mushroom body will die due to lack of water. 4. Spray water excessively. During the expansion of Pleurotus ostreatus fruit body, if the water spray is too easy to cause edema, the fruiting body is yellow and fester, and it is also easy to infect the bacteria and die. Second, take measures to ensure production 1. Select good strains to control the temperature. It should be noted that the strains that are suitable for the temperature type according to the mushrooming season should be selected. In the summer, the high temperature strains should be selected, and in the winter, the low temperature strains should be selected. At high temperatures, shade measures can be added to the mushroom sheds, and cooling measures such as spraying the water at the roof can be used. In case of sudden cooling, insulation measures should be taken to prevent excessive cold wind from entering the mushroom shed when ventilation is ensured. 2. Correct ventilation and humidification. Pleurotus ostreatus production process, we must pay attention to timely ventilation, and in the vents hanging thin cloth curtain, high temperature and ventilation when the curtain spray water, the dry hot wind into hot and humid wind, scrape dry hot air when the minimum ventilation, keep out The relative humidity of the air in the mushroom shed is about 80%. When the young mushroom is in the spray mode, it should be sprayed with cool water in the air and synchronized with the ventilation. 3. Comprehensive prevention and control of pests and diseases. When the temperature is high, bacteria and some pests can be easily bred. Spray in strict accordance with the prescribed concentration and use as little as possible. It is best to screw screens at the vents to prevent pests such as mushrooms from moving. The buds and mushrooms are removed in time and the contaminated bag is removed from the shed. When the temperature is low, diseases and insect pests are less likely to occur, mainly to prevent the introduction of pests and diseases in culture materials.
