After the winter, the harvesting period of Pleurotus ostreatus cultivated in autumn has not ended, but it is often constrained by the natural climate, and the amount of mushroom and the growth rate have declined compared with the temperature suitable period. In particular, when it comes to winter drought, low temperatures coupled with low humidity, if improperly managed, it will lead to phenomena such as dead mushrooms and malformed mushrooms. First, scientific water When the temperature is lower than 5°C and the relative humidity is lower than 70%, the metabolic function of the mycelia will be significantly weakened, and the growth rate of the fruit body will also be significantly reduced. At this time, the matrix material moisture content of the culture material should be controlled within 60%, and the amount of water sprayed on the bed surface should be reduced accordingly. The key should be to increase the relative humidity of the air, so that the relative humidity of the mushroom shed or mushroom house can reach 85%. ~ 90%. The slower growth of the mushroom body in the humidity will not only prolong its growth cycle but also reduce its yield. In addition, the quality of the mushroom body when dried is also poor. When the temperature is high every day, water can be sprayed into the space, the ground, the wall, etc. to increase the humidity in the mushroom shed or mushroom house. Second, double membrane coverage If small sheds are cultivated outdoors, such as low-temperature cold waves and strong winds, the temperature of the mushroom bed covered with double-layer membranes is better. Plastic canopies can be placed on small sheds where conditions permit. Without conditions, thick grass canopies can be placed on small sheds and covered with a thin film on grass rakes. It has been proved that the temperature of the mushroom bed covered with the double-layer film is 3°C-5°C higher than that of the single-layer film, which can significantly accelerate the growth rate of the mushroom body and increase the yield of the mushroom. Third, supplement nutrients After harvesting the first oyster mushroom, the nutrient and moisture of the cultivating material will be significantly reduced, and the re-grown omelet body will appear to have thin cover, fine stalk, single sown, small bundle, light color and cracked mushroom body. There is a direct relationship between nutrient content in the feed and severe shortage of water and degraded nutrient capacity of mycelium. When the temperature is low in winter, 3% of soybean milk slurry, 10% of Taomi water, and 0.5% of urea solution can be added to the culture medium in combination with supplementary water to adjust the carbon-nitrogen ratio of the culture material and enhance the activity of the mycelium. Improve production and quality. Fourth, reasonable ventilation In the cold winter, mycelium and fruit bodies did not stop growing and still undergo metabolism. Therefore, the ventilation and ventilation of the mushroom shed or mushroom house must not be neglected. Every day should be combined with water spray or mushroom ventilation when ventilation, the mushroom shed or mushroom house carbon dioxide content to a minimum, to ensure that the mushroom shed fresh air, daily ventilation at high temperatures for 1 to 2 hours. Fifth, material coverage The winter temperatures in the northern regions are mostly below zero or even a few dozen degrees. The winter management in these regions should put the cultivation materials in a relatively dry state after the autumn mushrooms are finished, and then loosen the material surface with rods to discharge the exhaust gas from the culture materials. And properly add nutrients and adjust the pH of the culture material, then cover 10 to 15 cm thick soil layer or 20 cm thick clean grass layer on the material surface film to facilitate insulation, and prevent the freezing of the material surface to freeze and damage the hyphae. Indoor cultivation should be kept at room temperature about 5 °C until the spring temperature rises after the cover is opened and then normal management.
