New technology of planting Pleurotus ostreatus with machine irrigation bag

Using the production technology of Lentinus edodes for reference to produce Pleurotus ostreatus, the new technology of planting Pleurotus ostreatus with machine irrigation and bag is summarized as follows:

I. preparation of bacterial bags

According to the formula cottonseed hull 88%, wheat bran 10%, gypsum 2%, water 1.1~1.2kg per kilogram of dry material. The material was poured into 55 × 15 × 0.004cm low-pressure polyethylene plastic bags with a special bag filling machine for Lentinus edodes production, and each bag was filled with wet weight 2.1~2.3kg. Then, put the material bag into the sterilization stove and sterilize it. After the temperature rises to 100 ℃, keep it for 10 hours and 12 hours, and transport it to the shaded greenhouse while the temperature is hot. When the temperature of the material drops below 30 ℃, put it in the inoculation box and inoculate 4 holes in the bag.

II. Management of the stage of bacteria transmission.

Sprinkle a thin layer of quicklime on the floor of the shed, and discharge the material bags with good seed according to the type of firewood, which is 6 stories high. About 7 days after inoculation, the mycelium in the inoculation hole spread radially. When the diameter reaches 3~4cm, tear off the sealing plastic film, pile the bacterial bag "well" shape code, two cylinders per layer, 6 layers is suitable, pay attention to the inoculation mouth facing outward (in order to produce mushrooms). Under the climatic condition of 15-20 ℃, the mycelium was full of material bags in about 20 days.

Third, management in the stage of mushroom production.

1. "well" type inoculation mouth mushroom: after the mycelium is full of bags, artificially increase the temperature difference between day and night to promote the mushroom bud, close the greenhouse film to increase the temperature during the day, and open both ends of the greenhouse at night to cool down. When mulberry-shaped mushroom buds appear at the mouth of the inoculation, spray water into the air to improve air humidity. The young mushroom grows for about 7 days, and the suitable harvest time is when the canopy is fully expanded and the cover is not crimped.

After the first batch of Pleurotus ostreatus was harvested, the water spraying was stopped for 3-4 days to restore the growth of mycelium and accumulate nutrients. Then spray water every day to moisturize, after about 10 days, the second batch of mushroom buds occurred.

two。 Change the "well" type inoculation mouth to produce mushrooms at both ends of the wall bag: after picking 2 batches of mushrooms, a large amount of water has been consumed in the culture material, so it is difficult to produce mushrooms. At this time, rearrange the bacterial stick to replenish water, and change the "well" type inoculation mouth to produce mushrooms at both ends of the wall bag. Specific methods: cut off the plastic film in the middle part of the bacterial bag with a blade, leaving a 8cm long "cap" at each end; flatten the ground and closely arrange the bacterial sticks with caps at both ends; adjust the soil into a paste, apply it to the bacterial stick and flatten it, and make the mud layer about 2cm; one layer of bacterial stick with a layer of mud, and five layers is appropriate, and pay attention to the aisle between each pile to operate mushroom picking; cut the film at both ends of the stick with a blade to facilitate mushroom production.

After that, the bacteria stick will get water replenishment from the mud to stimulate the temperature difference as far as possible, promote budding, and routinely moisturize and produce mushrooms.

3. Water replenishment method: when the 3rd and 4th batches of mushrooms are collected, the water loss of the mushroom stick is serious, and the water replenishment method is as follows: the special water injection needle for Lentinus edodes cultivation is directly inserted into the heap, replenish water with the help of submersible pump or tap water pressure, and then stimulate the temperature difference to moisturize and produce mushrooms.

Lentinus edodes cultivation bag machine irrigation cultivation of Pleurotus ostreatus, generally bagged dry material 1.1kg, mushroom 7-8 tide, fresh mushroom 2.5kg above, bioconversion rate 200%-300%. This method has the advantages of labor-saving (1 ton feeding machine irrigation, 4 people can complete the bag filling process in 2.5 hours), mushroom production quickly (about 20 days), good quality (clinker cultivation formula does not contain germicidal insecticides, water replenishment is clear water over and over again) and so on.
