1. Control temperature
The temperature range for the growth of the ears of Auricularia auricula is 16℃-35℃, and the most suitable growth temperature is 24℃-28℃. In this temperature range, the higher the temperature, the faster the growth of the ears. When the temperature is lower than 18℃, the ears grow faster. The growth of the tabs is slow, and the growth of the tabs is inhibited when the temperature exceeds 35°C. When the temperature is lower than 20°C, reduce ventilation and do a good job of heat preservation. When the temperature exceeds 33℃, pay attention to spraying water to cool down and strengthen ventilation.
2. Adjust humidity
The growth and development stage of the ears of hairy fungus requires a relative humidity of 85%-95%. The relative humidity of the air can be maintained by artificial water spraying. When spraying water, a water pipe can be used to spray directly to the ears and the space, but mainly to the space and Water the ground. The water spray should be based on the climate and the growth conditions of the ears. When the ears are sunny, the temperature is high, and the ears are large, the amount of water should be large, spray water 3-4 times a day; on cloudy days, the ears are hours, less spray or Do not spray water. When the edges of the ears are curled, blackened and hardened, it indicates that the humidity in the environment is insufficient, and water should be sprayed in time. Hair fungus ear pieces have strong drought tolerance. Even if the ear pieces turn black and hard, dry and curl, they can regain their growth after being restored by spraying water. Therefore, the management should be dry and wet to keep the environment dry and dry. The wet state helps to improve the quality and yield of the ears.
During the high temperature period, it is especially necessary to do a good job in the alternate management of dry and wet. After each spray of water, combined with ventilation, let the excessive water on the ears of the fungus shed. In continuous rainy days, ventilation must be increased to prevent "fluid ears".
Three, increase light
The intensity of the light has a great influence on the quality of the ears. Under strong light, the ears will grow thick, dark, soft, thick and long, and the ears will be black when they are dry. In low light or close to dark conditions, the ears are light in color, light red, the ears are thin, and the ventral hairs are thin and short, not obvious. After drying, the ears are reddish brown and translucent. Therefore, by adjusting the light intensity of the ear environment, ear pieces of different quality can be produced to meet the needs of the market.
Fourth, maintain ventilation
During the growth and development of the ears, the hairy fungus has to absorb a lot of oxygen and emit carbon dioxide. If the ear canopy is not well ventilated, it will cause a high concentration of carbon dioxide environment, and the ears cannot be differentiated and formed normally and grow into a "finger shape". "The fruit body. In the late stage of ear piece growth, when the temperature is high and the humidity is high, it will cause "fluid ears". Therefore, during the ear-out period, keep the air in the ear shed smooth and fresh. Since ventilation is contradictory to heat preservation and moisturizing, ventilation must be carried out according to temperature and humidity. For low temperature and low humidity, reduce ventilation; for high temperature and high humidity, increase ventilation; in continuous rainy days, always maintain ventilation, reduce humidity, and prevent "flow ears".
Five, the management of the second ear
Under normal circumstances, the hairy fungus can be harvested continuously for 3-4 crops, 1-2 crops are of high quality, and the ear quality after 3 crops is poor. After the first crop is harvested, in order to promote the rapid change of tide to grow the second crop of fruit bodies, the management should pay attention to the following links:
1. Clean the ear base. After the first crop of fruit bodies are harvested, if the ear base is not cleaned, mildew will easily appear when the temperature is high, which will lead to contamination by bacteria and no regeneration. For this reason, the whole flower should be cut along the bag surface when harvesting, and the residual ear base on the hole should be removed with a sharp knife.
2. Control moisture and cultivate bacteria. After harvesting the bacteria bag, stop spraying water for 3-5 days, at the same time strengthen ventilation, and dilute the cover on the shade, increase the light, and shrink the surface moisture. The hyphae in the bag continue to absorb nutrients and switch from reproductive growth to vegetative growth. At this time, the temperature should be controlled at 24°C-26°C to promote the regeneration of the mycelium and provide strong mycelium conditions for the second harvest.
3. Humidifying ears. After the fungus is harvested, the water in the medium has been consumed. In order to induce the formation of primordium, it is necessary to spray a small amount of atomized water on the surface of the material, remove the film and ventilate normally every day, and renew the air in the shed. At the same time, use temperature difference stimulation and alternate dry and wet to promote the rapid formation of primordium and differentiation into ear buds Into fruiting bodies.
After each fruit body is harvested, since the water and nutrient content in the bag are relatively reduced, the number of sprays and the amount of spraying should be increased accordingly. You can also spray some yield-increasing elements to increase nutrition and promote hair. The agaric ear pieces are thick and increase the yield.
