According to the number of plants, Jianfa mushroom sheds generally cover an area of 120 square meters per 10,000 bags. The brightness in the sheds should not be too high, otherwise it will affect the normal growth of mycelia.
Calculated on the basis of 10,000 bags, 11 tons of wet coarse sawdust, 3 cubic meters of fine broad-leaf sawdust, 2 tons of bran, 100 kg of sugar, 100 kg of gypsum and other materials must be prepared for use.
① Stir the coarse and fine sawdust, bran, and gypsum thoroughly, and fully melt the sugar into the water. Sprinkle the water evenly over the blended ingredients. The amount of water is determined according to the dryness and wetness of the sawdust, and it is advisable to make the water after mixing reach 65%-70%.
②Put the material into a 53cm×15.2cm mushroom bag with a bagging machine. The weight of the packed mushroom bag is 1.8-1.9kg. If it is too tight, it is easy to produce bagging, and if it is too loose, it will affect its output and the fungus bag is easy to break.
It is usually sterilized by normal pressure, and it is advisable to pack 3000-3500 bags per pot. Use steam to bring the fungus bags to 100°C and steam for 20 hours to kill harmful bacteria in the material.
Lower the temperature below 25°C in a closed manner, and then sterilize the sterilized bacteria bags by fumigation for 3-5 hours. Then punch 4 holes on the front of each bag, stuff the fungus material tightly, and stick it firmly with adhesive tape.
After recovering the bacteria bags that have been connected with the strains at room temperature for 2 days, raise the temperature to 18-25°C for germination, and keep the bacteria chamber clean. When the bacteria grow to 10 centimeters, puncture the holes to release oxygen, and change the original 4 stacked together to 3, so that the air can fully enter the stack. When the bacteria grow to the back side, oxygen release is performed for the second time, and the number of puncture holes is 18-22.
In the later stage of the germination process, the bacteria bag itself generates heat, and the temperature should be kept below 28°C.
Go to the ground
In June, take off the outer bag of the fungus bag, go down to the small shed that has been built, and fill the seams of each bag with fine sand. At the same time, micro-spray or artificial water spray should be used to prevent the bacteria bag from losing water. According to the weather, spray water 3-4 times a day. The shade net density of the fruiting shed should be above 90%.
After 3 to 5 days of water spraying, the small mushroom buds will grow up, and the dense and deformed mushroom buds should be removed. As the mushroom buds grow up, the amount of water spray should be gradually reduced, otherwise the quality of the mushrooms will be affected. The fruiting shed should not exceed 25°C, and the mushrooms should be picked according to the quality of the harvested mushrooms, at least 3 times a day.
Management after the second crop of mushrooms
As the number of mushrooms decreases, increase the number of water sprays to replenish water, so that the water can be fully replenished and the bacteria will be stopped. After the bacteria have rested, use rubber or soft foam to vibrate the bacteria sticks to stimulate the fruiting. As the number of mushrooms grows, the rods will shrink, and cracks will form between the rods, and the cracks should be smoothed out with fine sand in time.
