Corncob bean curd mix Pleurotus ostreatus

Use corn cob and bean curd residue as medium to cultivate Pleurotus ostreatus. Because bean curd residue and corn cob contain rich crude protein, crude fat and amino acid and other nutrients, 50-75 kg of fresh mushroom can be produced per square meter, and the biological efficiency can reach 150. %-200%, considerable economic benefits. The high-yield and high-efficiency technologies for the co-cultivation of Pleurotus ostreatus with corn cobs and bean curd refuse are described below.
1, the ratio of culture materials. Crushed corn cob 100 kg, wet bean curd residue 80 kg, white ash 6 kg.
2, spices bags. Firstly, the wet bean curd residue and white ash were diluted with water and poured into the corn cob and mixed until the moisture content of the culture material reached 65%. A 50x25x0.05 cm polyethylene low-pressure plastic cartridge was used for loading and compaction (about 1.25 kg of dry material per bag), and both ends were tied with a string.
3, sterilization. The bacteria bags are sterilized at normal pressure, the temperature reaches 100°C, and they are maintained for 8-10 hours. After the ceasefire, they are simmered for 8-10 hours. After the pan is out, the material temperature is cooled to below 30°C for inoculation. The inoculation room is to be sterilized twice. The fungus bag was fumigated with potassium permanganate and formaldehyde (1:3) before being transferred to the inoculation room, and the bacteria bag was transferred to the inoculation room and disinfected once with a mist sterilization box.
4, strain selection. Nanjing No. 1, Life No. 1, ccef89, and Jiuping No. 1 were all suitable for cultivation. The mycelium grew robustly, turned fast, and yielded high quality. The third-grade strains are suitable for 30 and 40 days.
5, inoculation method. The inoculation method was adopted at both ends of the bag and 3 holes in the middle. The cultivars should be diced into small pieces of peanuts, not too crushed. The inoculum size is about 15% of the feed weight. This method of bacteria germination fast, quickly occupying the material surface and reduce bacterial infection.
6, bacteria management. Transfer the seed bag to the culturing room and place it in a row. Two bags of inoculated larvae are opposite. The stack is 5-7 layers high and each line is 50 centimeters apart. The room temperature is about 15 °C, more than 25 °C immediately ventilated cooling, control the material temperature below 25 °C, culture about 10 days, to turn a heap, the upper and lower exchange. About 30 days can be filled with bacteria bags.
7, except for bacteria. In the fungus bag germination process, if any bacteria are found to grow, use 95% alcohol, 5% formaldehyde, 20% lime water, 5% lime carbonic acid, diesel and other fungicides, use a syringe to inject it into the growth of bacteria In the culture medium, the permeation area and the depth of the liquid medicine are all greater than the growth area of ​​the bacteria to effectively control the bacteria. If the area of ​​the bacteria in the bag is too large to be controlled by liquid medicine, it must be picked up and taken out of the house.
8, rake type cover soil cultivation. Dig soil to make hoe, hoe width 1 meter, depth 35 centimeters, length is not limited, at the bottom and around the bottom of a spray insecticide, fungicide (80% dichlorvos emulsion 1000 times and 10% lime water). Then, the mycelium-filled bacterial bag was removed from the plastic bag and placed in a vertical position. The bacterial column was separated by 2 meters. The cavity was filled with the moist soil and compacted. The nutrient water was made into water (100 kg of urea and urea were prepared. 500 g, potassium dihydrogen phosphate 300 g, magnesium sulfate 200 g, lime 4 kg). The cover soil should be flush with the material surface, and the residual soil on the material surface should be flushed with water to expose the end surface, and then the plastic film should be covered. The surrounding of the plastic film should not be compacted for ventilation.
9, mushroom management. In order to promote the formation of fruiting bodies, it should be ventilated for one hour every day. When the temperature is higher than 15°C, it should be ventilated at night; when the temperature is lower than 10°C, it should be ventilated at noon. At the same time, the plastic film on the surface will be opened for ventilation. After a few days, there will be a large number of bacterial buds that grow rapidly. The top is covered with the original cap, the membrane is opened, the water is sprayed into the air every day, and the relative humidity in the room is maintained at about 95%. From fruiting body formation to harvesting, it takes about 7- 10 days.
10, harvest. Picking is performed when the edge of the cap is in the form of a copper cocoon. At this time, the quality of the mushroom is good, the weight is large, and the tide is fast. After picking, the sorghum should be cleaned and sprayed for 3-5 days. Then the sluice should be poured once more to keep the sorghum surface moist. About 1 week later, the sorghum buds grow again, still pressing the first batch of mushrooms. Management method management. Usually 4-6 batches are harvested, and the whole growth period is 4-6 months.
