Guide to cultivation techniques and management techniques of Agaricus blazei

Vaccination

The inoculation and germination of Agaricus blazei, bagging and seeding tube bags are generally made of 22 to 24 cylinders with a flat width of 42 to 45 cm. For germ management, clean the mushroom shed before use, spray with 100% solution to remove traces and phoxim solution, in order to inhibit the killing of bacteria, insects and insects. After sealed and exposed for 2 days, you can move the bacteria into the bag Germ room.

Note that when the mushroom shed develops bacteria, the relative humidity of the air should not be adjusted to more than 70%. If the germs occur in early autumn, the doors, windows, and vents of the germ shed (room) need to be covered with insect-proof nets to prevent pests from flying in. The bagging and seeding of Agaricus edodes is about October. At this time, the highest temperature is 24 ° C, which is the best season for germination of Agaricus edodes. However, the germbag itself can generate biological heat. Therefore, how to arrange the bags depends on the temperature. If the temperature is higher than 20 ℃, it should be discharged in a single layer without code height to prevent burning bacteria. When it is below 15 ℃, it can be coded with 2 ~ 4 layers, and a bamboo rod with a diameter of 2 ~ 3cm should be used to lift between layers. There should be a space between the bags, one yard for every two rows, and a walkway of 30 ~ 50 cm between each yard, so as to observe the temperature and ventilation, and avoid large piles.

During the germination period, the method of spraying alcohol is used to prevent the invasion of germs. Generally, you can use Alzheimer's No Trace and Saibai 09 to alternate or cooperate. The direction of the medication is the ground, wall, ventilation hole and doorway. Observe two each morning and evening. It is advisable to keep the bag temperature at 22 ~ 30 ℃, and the highest temperature should not exceed 30 ℃. For low temperature, use stacking, cover stacking and other methods to heat up and keep warm; when the temperature is high, you can use methods such as layer reduction, single row stacking and ground watering to cool down.

In short, the most important task during the germination period is to strictly prohibit the high temperature of the product to prevent unnecessary loss of burned bacteria. Generally, after about 20 to 30 days, the germ bag can complete the germination. According to the "bursting mushroom" technology Requirement, refer to the management of Pleurotus ostreatus for post-ripening cultivation of mycelium; after about 15 days of post-ripening, you can increase the light to 1000 lux, control the temperature at about 20 ° C, and increase the temperature difference above 10 ° C, and humidity of 90% Left and right, as well as good ventilation, to promote budding, usually about 7 days, the mushroom buds appear, and then enter the mushroom management stage.

Mushroom management

(1) Temperature: The temperature of the Agaricus edodes is lower than the temperature required for the germination period. The optimal temperature for the growth of fruiting bodies of general strains is 12 ~ 18 ℃, which is slower than 10 ℃, and higher than 20 ℃ will cause The mushroom body is thin, the cap is thin, and the color is yellow, which may even cause the young mushrooms to die or be prone to parasitic bacteria. Therefore, taking measures to regulate the temperature is an important task in the management of the mushrooms' emergence. When the temperature is higher than the proper temperature, you should increase the ventilation, increase the humidity in the shed, and cover the roof with shades to lower the temperature; when the temperature is lower than the proper temperature, you can use the greenhouse effect by pulling shades such as draft curtains To increase the internal temperature, or to increase the temperature in the shed by using water temperature and air conditioning.

(2) Moisture: The relative humidity in the mushroom shed is about 90% at the young mushroom stage. When the humidity exceeds 90%, ventilation should be increased to reduce humidity. When the relative humidity is less than 85%, it can be kept in the shed when the winter temperature is low. Make a stove, boil water on the stove with steam to both warm and humidify; in the spring and autumn, you can spray cool water on the space, the ground, and the wall to cool down and humidify, but spray less frequently, and do not spray water on the mushroom body.

(3) Ventilation: As the fruit body of Agaricus blazei grows, the demand for oxygen also increases, and the concentration of edge growth should not exceed 1%. It is based on normal people not feeling very stuffy in the shed. If the concentration is too high, the young Mushrooms will not grow caps due to lack of oxygen, forming abnormal mushrooms and dead mushrooms. However, if the ventilation is too large, the growth of the fungus cover will be too fast and the growth rate of the stalk will be relatively reduced, which will make the Agaricus edodes grow into ordinary Pleurotus ostreatus and reduce the value of the commodity.

(4) Light: With appropriate concentration in the young mushroom stage, it can stimulate the growth of the mycelium to accelerate the growth and inhibit the development of the cap.

(5) Harvest: spray edible fungus nutrient (spray type) at the young mushroom stage; spray it once every other day at 15 ° C for 3 times; the diameter of the bacteria cover is between 1 ~ 3 cm In the meantime, the color is slightly lighter than the young mushroom period. When the stalk is 5 cm long, it should be harvested in time.
