Use corn cob and bean curd residue as medium to cultivate Pleurotus ostreatus. Because bean curd residue and corn cob are rich in crude protein, crude fat and amino acid, 50-75 kg of fresh mushrooms can be produced per square meter, and the biological efficiency can reach 150%~200. %, considerable economic benefits. Its high yield and high efficiency technology are as follows.
1. Culture material ratio. 100 kg of corn cob, 80 kg of wet bean curd, and 6 kg of lime.
2 spices bagging. The wet bean curd residue and lime were diluted with water and poured into the corn cob and mixed until the moisture content of the culture material was 65%. A 50 cm x 25 cm x 0.05 cm polyethylene low-pressure plastic cylinder was used for loading and compaction (about 1.25 kg of dry material per bag) and the two ends were tied with a string.
3. Sterilization. The bacteria bags are sterilized at normal pressure and maintained at 100°C for 8-10 hours. Boring 8-10 hours after a ceasefire. After the pan was removed, the material was inoculated with the temperature cooled to 30°C. The inoculation room is sterilized twice. The bag was fumigated with potassium permanganate and 3 parts of formaldehyde before moving into the inoculation room. After the bacterial bag is moved into the inoculation room, it is sterilized with a mist disinfection box once.
4. Selection of strains. Select Nanjing No. 1, Life No. 1, ccef89, and No. 1 No. 1 strains. The bacteria age of the tertiary strains is 30-40 days.
5. Inoculation method. Take the inoculation method 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 weight is 15% by dry weight. This method of bacteria germination fast, can quickly occupy the material surface and reduce bacterial infection.
6. Fungus management. The inoculated bag was moved to the culturing room and placed in a row. The stack height was 5-7 layers, and each line was 50 cm apart. 15t is appropriate at room temperature. Ventilation is immediately reduced when the temperature exceeds 25°C, and the temperature of the material is controlled at 25°C or below. After 10 days of cultivation, they were piled up and exchanged between the upper and lower layers. 30 days can be filled with bacteria bags.
7. Miscellaneous bacteria treatment. In the fungus bag germination process: if any bacteria are found to grow, use 95% alcohol, 5% formaldehyde, 20% lime water, 5% carbolic acid and other fungicides, use a Syringe to inject it into the culture of the growth of bacteria In the material, the permeation area and depth of the liquid medicine are all greater than the growth area of ​​the bacteria to prevent and control the bacteria. If the area of ​​the bacteria in the bag is too large to be controlled by liquid medicine, it should be picked out and handled outdoors.
8. Cocoon cover cultivation. Digging soil to do 畦, 畦 1 meter wide, 35 cm deep, unlimited length. Insecticides and bactericides (80% dichlorvos emulsion 1000x and 10% lime water) were sprayed on the bottom of the loach and around the surface. Then, the hyphae-laden 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 moist soil and compacted. The nutrient solution was watered with 100 kg of water and urea. Grams, potassium dihydrogen phosphate 300 grams, magnesium sulfate 200 grams, lime 4 kilograms). The cover soil and the material surface are the same. The residual soil on the material surface is flushed with water, exposing the material surface, and then covering the plastic film. The surrounding is not compacted for ventilation.
9. Mushroom management. In order to promote fruit body formation, ventilate for 1 hour every day. When the temperature is higher than 15°C, it is ventilated at night; when the temperature is lower than 0%, it is ventilated at noon. At the same time, the plastic film on the surface will be opened for ventilation. A few days later, there were a large number of buds growing. The top was covered with the original bacteria. The film was peeled off and sprayed into the air daily to keep the relative humidity of the room air at 95%. From the fruiting body formation to the picking took 7-10 days.
10. Harvest. Picking when the edge of the cap is copper-shaped. At this time, the quality of the mushroom is good, the weight is large, and the tide is fast. After picking, clean the pasta and stop spraying for 3-5 days. Then pour water into the bowl once to keep it moist. One week later, the buds sprouted again and were still managed according to the first batch of mushroom management methods. Generally 4-6 batches are harvested, and the whole growth period is 4 months.
