First, control the temperature
The growth temperature of the ear fungus is 16 °C-35 °C, and the optimum growth temperature is 24 °C-28 °C. In this temperature range, the higher the temperature, the faster the ear growth, and the temperature is lower than 18 °C. The sheet grows slowly and the growth of the ear is inhibited when the temperature exceeds 35 °C. When the temperature is lower than 20 °C, reduce ventilation and do a good job of insulation. When the temperature exceeds 33 °C, pay attention to the water spray to cool down and strengthen the ventilation.
Second, adjust the humidity
The growth and development stage of the ear fungus ear requires air relative humidity of 85%-95%. The relative humidity of the air can be maintained by artificial water spray. When spraying water, the Water Pipe can be directly sprayed onto the ear piece and space, but mainly to the space and Watering the ground. The water spray should be determined according to the climate and the growth condition of the ear. When the weather is high, the temperature is high, and the ear is large, the water spray volume is large, and the water spray is 3-4 times a day. On cloudy days, the ear piece is small, and the water is sprayed less. Do not spray water. When the edge of the ear is curled and becomes black and hard, it indicates that the humidity in the environment is insufficient, so it is necessary to spray water in time. The ear of ear fungus has strong drought tolerance. Even if the ear piece becomes black and hard, dry and curled, and the water spray can be restored after water and water, it can resume growth. Therefore, the management should adopt dry and wet communication to make the environment dry. The wet state helps to improve the quality and yield of the ear.
During the high temperature period, it is necessary to do a good job of alternating wet and dry management. If it is in a high temperature and high humidity environment for a long time, it is easy to appear "flow ear". After each water spray, combined with ventilation and ventilation, the excess water on the ears of the fungus is dissipated. In continuous rainy days, ventilation must be increased to prevent "flowing ears".
Third, increase the light
The intensity of light has a great influence on the quality of the ear. Under strong light, the grown ear is thick, dark and soft, and the fluff is thick and long. After the ear is dry, it is black. In low light or near dark conditions, the ear is light in color, light red, the ear is thin, the belly is thin and short, not obvious, and the ear is reddish brown and translucent after drying. Therefore, by adjusting the light intensity of the ear environment, different quality ear pieces can be produced to meet the needs of the market.
Fourth, keep ventilation
During the growth and development of the ear, the hair fungus should absorb a large amount of oxygen and emit carbon dioxide. If the ventilation in the ear shed is poor, it will cause a high concentration of carbon dioxide environment, and the ear piece will not form normally, but grow into a "finger shape." "The child entity." In the later stage of the growth of the ear piece, when the temperature is high and the humidity is high, the "ear ear" will be caused. Therefore, during the earing, the air in the ear shed is kept smooth and the air is fresh. Because ventilation is inconsistent with heat preservation and moisturizing, it should be carried out according to temperature and humidity during ventilation. Low temperature, low humidity, reduce ventilation; high temperature, high humidity, increase ventilation; in continuous rainy days, always keep ventilation, reduce humidity, prevent "ears".
Management of five or two ears
Under the normal circumstances, the fungus can receive 3-4 连, 1-2 多 more quality, 3 茬 after the ear quality is poor. After harvesting the first scorpion, in order to promote the rapid development of the second scorpion entity, the management should pay attention to the following links:
1. Clean the ear base. After the first scorpion entity is harvested, if the ear base is not removed, when the temperature is high, it is prone to mold and rot, resulting in contamination of the bacteria and failure to regenerate. To this end, the harvest should be cut along the entire surface of the bag, and the residual ear base on the hole should be removed with a sharp knife.
2. Control the wet bacteria. The post-harvest bag should stop spraying for 3-5 days, at the same time strengthen the ventilation, and thin the cover on the shed, increase the light, and make the surface water shrink. The mycelium in the bag continues to absorb nutrients, and the original reproductive growth is transferred back to vegetative growth. At this time, the temperature should be controlled at 24 ° C - 26 ° C to promote the rejuvenation of the bacteria and provide strong mycelial conditions for the second ear.
3. Humidify the lure. After harvesting the hair fungus, the water in the medium has been consumed. In order to induce the formation of primordium, a small amount of sprayed surface must be sprayed with atomized water. The film is normally ventilated every day to renew the air in the shed. At the same time, the temperature difference is used to stimulate the dry and wet alternately to promote the rapid formation of the primordium and differentiate into ear buds. Become a child entity.
After harvesting each scorpion body, since the moisture and nutrient content in the bag are relatively reduced, the number of water sprays and the amount of water sprayed should be increased accordingly, or some stimulation can be sprayed to increase nutrition and promote hair. The fungus ear is thick and increases the yield.
