Grown fungus in plastic bags is usually made of polypropylene plastic bags that are 33cm long, 17cm wide, 0.06cm thick, or 18cm long, 12cm wide, and 0.06cm thick. The key to the success of bagged fungus is to overcome the problem of bacterial contamination. In addition to the good original species, the use of high-quality plastic bags, to minimize bag damage during the operation is also an important factor to improve the yield. Before loading the material, the quality of the plastic bag must be strictly inspected. Bonding is not strong and there is no need for sand eyes. Fill the bottom two corners inwards to 1/4 before loading. This will make the bag square and easy to stand upright and operate. 1 Mixing, bagging and sterilizing: Select one of the above-mentioned recipes, mix the ingredients in proportion, make the water content about 60% and then carry out bagging, and also stack the mixed materials into 1.5m high and 1m The wide trapezoidal pile of material is fermented for 5-7 days, and is turned in the middle 1-2 times. Then it is bagged again and the loading is slightly compressed. The bag mouth is covered with a hard plastic ring with a diameter of 3cm and a height of 2-3cm. The plastic is then re-rolled into a bottle-like mouth, stuffed with a tampon, or sealed with a plastic double-layer newspaper, and then fastened with a rubber band. . 2 Inoculation, culture: After sterilization, the temperature is lowered to below 30°C for inoculation. After inoculation, the bag is immediately transported into the culture room for cultivation. The management points during the cultivation are the same as those for the bottle planting. 3 ear ear management management method can be divided into two kinds of ear management methods: (1) on the indoor training ear ear culture room before use, indoor and outdoor environments should be carefully washed, pest sterilization, the old ear should strengthen cleaning and disinfection work. The cultivation room requires good moisturizing performance, the area should not be too large, the light is sufficient, the ventilation performance is good, and the cement floor is convenient for frequent flushing. When the fungus bag is moved into the ear chamber, it is appropriate to open the hole when the surface of the material to be cultured begins to appear. The appearance of the primordium indicates that the mycelium is transferred from the vegetative growth to the reproductive growth stage. When opening the hole, the surface of the bag is first sterilized with 0.1% potassium permanganate, remove the tampon and plastic ring, cut the plastic bag higher than the culture part, and open 10 holes with a diameter of 1.5-2cm around the bag. , And pay attention not to damage the hyphae, and then put the plastic bag upside down on the culture shelf, cover the film to facilitate heat preservation and moisturizing, promote ear bud formation. Ear bud formation temperature is 15-20 °C. In order to prevent mycelium from dehydrating, several sprays of space are performed daily. At the same time, light and oxygen are sufficient. After about 10 days, the ear can be heard and the film can be removed. After the formation of ear buds, the body grows rapidly and the metabolism is vigorous. The nutrients in the mycelium are transferred into the fruit body in large quantities and can grow up to about 0.5cm in one day. Sprinkle water 2-3 times a day, the amount of water spray to keep the ear wet, stretching is appropriate. At the same time pay attention to ventilation, ear buds can mature after two weeks. After the ear was collected, the water spray was stopped for 3-4 days, and then the water was sprayed. After one week, the ear buds were formed again, and the ears were generally received 3-5 times. (2) Outdoor arbor hanging bag cultivation ears to create air circulation, no pollution around the source, there is a certain place of light, the average daily temperature of 15 °C or so. The ground is covered with fine sand, lime, and ear racks are placed under a shed or in a sparse forest. About 2 meters high, the plastic bags are arranged in different heights on the ears. The lowest layer of bags should be 33cm above the ground. When the bag appears primordial, the surface of the bag should be disinfected with 0.1% potassium permanganate solution. Use a clean blade to open 8-10 2-cm diameter “+†shaped ports where the ear buds appear. After opening, the relative humidity of air is maintained at 80-90%. With the increase of ear buds and the growth of the ears, the humidity gradually increased. The temperature during earing should be controlled below 22°C and should not exceed 24°C.
