Shimeji mushroom cultivation techniques and management techniques guide

Inoculation

For the inoculation of Shimeji mushroom, the bagged seeding tube is generally 22~24 in flat width and 42~45 cm in length. Bacterial management, clean the mushroom shed before use, and spray the phoxim solution and phoxim solution to kill bacteria, insects and insects. After airtight and exposed to the sun for 2 days, the bacteria can be packaged. Move into the hair germ room.

Pay attention to the growth of bacteria in the mushroom shed, the relative humidity of the air should be adjusted to not exceed 70%, and other treatments are the same as the growth room. If the bacteria develop in early autumn, the doors, windows, and vents of the bacteria shed (room) must be enclosed with anti-insect nets to prevent insects from flying in. Shimeji mushrooms are bagged and planted around October. At this time, the highest temperature is 24℃. This is the season for Shimeji mushrooms to grow. However, the bag itself can generate biological heat. Therefore, how to arrange the bags depends on the temperature. It depends. If the temperature is higher than 20℃, it should be discharged in a single layer to prevent burning bacteria. When the temperature is below 15℃, the height can be 2~4 layers, and the diameter of 2~3 cm should be used between layers. Stand up on the bamboo pole, leave a gap between the bag and the bag, every two rows are one yard, and leave a 30-50 cm aisle between each yard to observe the temperature and ventilation, and avoid large piles.

During the period of bacteria development, the method of spraying *** drugs to prevent the intrusion of bacteria can generally be used to alternate or cooperate with Baibing Quwuxiang and Saibai 09. The direction of application is the ground, wall, vents, and doorways; each morning and evening Observe the bag temperature twice, keep it at 22~30℃, and do not exceed 30℃. When the temperature is low, use methods such as stacking and covering to heat up and keep warm; when the temperature is high, methods such as layer reduction, single-row stacking and ground watering can be used to cool down.

In short, the main task during the germination period is to strictly prohibit the product from overheating to prevent unnecessary losses caused by the burning of the bacteria. Generally, the bacteria bag can complete the germination after about 20 to 30 days. Requirements, refer to the management of oyster mushrooms, and carry out post-ripening culture of mycelium; after about 15 days of post-ripening, you can increase the light to 1000 lux, adjust the temperature at about 20 ℃, and increase the temperature difference by more than 10 ℃, and the humidity is 90% The buds will be invigorated with good ventilation. Usually, after 7 days, mushroom buds will appear, and then enter the fruiting management stage.

Fruiting management

(1) Temperature: During the fruiting stage of Shimeji mushrooms, the temperature is lower than the temperature required for the germination stage. The optimum temperature for the growth of fruit bodies of general strains is 12~18℃, which will grow slowly when the temperature is lower than 10℃. The mushroom body is thin, the cap becomes thin, and the color becomes yellow. It may even cause the death of young mushrooms or easily produce parasitic bacteria. Therefore, taking measures to adjust the temperature is an important task for the management of Shimeji mushroom fruiting period. When the temperature is higher than the proper temperature, increase the ventilation, increase the humidity in the shed, and cover the roof with shade to cool down; when the temperature is lower than the proper temperature, the greenhouse effect can be used by drawing shades and other shades To increase the internal temperature, or use water temperature air conditioning to increase the temperature in the shed.

(2) Moisture: During the young mushroom stage, the relative humidity in the mushroom shed is required to be around 90%. When the humidity exceeds 90%, increase ventilation and dehumidification; when the relative humidity is less than 85%, it can be in the shed when the temperature is low in winter. To make a stove, boil water on the stove and use steam to heat and humidify; in spring and autumn, cool water can be sprayed on the space, the ground, and the walls to both cool and humidify, but spray less frequently and do not spray water on the mushroom body.

(3) Ventilation: With the growth of Shimeji mushroom fruiting bodies, the demand for oxygen is also increased. The marginal concentration should not exceed 1%. Normal people do not feel very stuffy in the shed. If the concentration is too high, Mushrooms will not grow caps due to insufficient oxygen, forming deformed mushrooms and dead mushrooms. However, too much ventilation will cause the cap to develop too fast and the stalk growth rate will be relatively reduced, making Shimeji mushrooms grow into ordinary oyster mushrooms, reducing the commercial value.

(4) Light: In the young mushroom stage, with an appropriate concentration, it can stimulate the growth of the stalk and inhibit the growth of the cap.

(5) Harvesting: spray edible fungi nutrient essence (spray type) at the young mushroom stage; spray once every 1 day for 3 times at 15℃; the diameter of the cap is 1~3 cm The color is slightly lighter than the young mushroom stage. When the stalk is 5 cm long, it should be harvested in time
