Technical Points of Efficient Cultivation of Oyster Mushrooms with Corncob

It is estimated that 100-150 kilograms of fresh mushroom can be produced per 100 kilograms of corn cob, and the bioconversion rate is 150%-250%.

Material selection and processing. The corncob that was fresh and without mildew in the year was exposed to sunlight for 2-3 days and crushed to the size of corn kernels without sieving. The culture materials were prepared.

Loading and inoculation. When the material temperature drops below 30°C, it can be bagged and 5025 cm polyethylene tube bag is used to inoculate according to the three-layer material four-layer strain inoculation method. The quantity is inoculated in 3:2:2:3, and the seeding rate is 10%-15% of the material weight. The planted material bag is tied to the sides and upwards and the height is 1.5-2 meters.

Hyphae cultivation. Two days after sowing, the temperature of the material began to rise. Attention should be paid to changes in the temperature of the material every day. After 2 to 3 days, the reactor should be turned one at a time. After 6-7 days, the reactor should be turned again to prevent the temperature of the material from rising above 35°C. When the material temperature rises to 32°C, the doors and windows should be opened in time to spray water on the ground to reduce the accumulation level, and the bacteria bags should be scattered to disperse the heat in the bags quickly to reduce the temperature of the material. The temperature of the bag should be controlled at 25°C. About 10 days or so, the bag turns 180 degrees, so that the bottom of the stagnant water, in order to facilitate the uniform germs, about 20 days and then bag down, put the mycelium growth good bacteria bags together, poorly placed Together, it was contaminated and the pollution was light. Open the bag mouth and put it in the shade for a few days or use lime powder to cover it. The relative humidity of the indoor air is kept at about 65%. Generally, after 30 days, the mycelium can be filled with bacteria bags.

Mushroom management. When the material surface is covered with white hyphae, the zigzag on both sides of the bag can be unlocked, the bag mouth is rolled outwards, ventilation is enhanced, the room temperature is maintained at 14-18°C, and the relative humidity of the air is controlled at 85%-90%. Do not spray water buds, when the young mushrooms should be a small amount of water, grow to the size of beans, the number of water spray to increase, maintain air humidity 90%, at 10-25 °C under 5-7 days can be harvested. After harvesting the first oyster mushroom, the smashed mushroom shards are cut, and the water is sprayed again to seal the material surface and the same as the original, to keep the indoor air slightly dry, to promote the growth of mycelium and accumulation of nutrients, and strengthen the ventilation and light transmission. After the mushroom is formed, it is normally managed. After harvesting 2-3 oyster mushrooms, 0.2%-0.3% urea or potassium dihydrogen phosphate may be sprayed. The temperature during the entire growth period is controlled at 10-25°C and the humidity is 80%-95%.
