To cultivate shiitake mushrooms with corn cobs, it is necessary to crush the corn cob shaft rods after removing the corn kernels into crumbs, and add a certain amount of auxiliary materials to prepare the culture medium, which can be used for the corn kernel suitable “EX03†mushroom varieties. Cultivation. Its mushrooming temperature is 5-25 °C. Its mushroom quality and color are the same as that of the wood chips substitute mushroom, and its yield is higher than sawdust. Now we will introduce the cultivation techniques as follows: 1. Formulation of culture materials: 1. Formula: 80% of corn chips, 18% of wheat bran, 1% of gypsum powder and white sugar, 0.3% of potassium dihydrogen phosphate, and 130% of water. 2. Preparation method: According to the proportion of formula, mix and stir the mixing ground and mix for 2 hours. After the mixture is mixed, check the moisture content about 65%, that is, grasp the ingredients tightly and form water droplets between the fingers. No drop for the degree. Then build a pile of fermentation, turn 2-3 times in the middle. First, bagging sterilization: 1. Bag making tube. The width of 15 cm polypropylene plastic tube film were cut into 55 cm long, one end of the tube film is tied with a string, and the film head is placed on the flame of the candle and the barbecue is melt-sealed into a bag barrel. 2. Loading. The fermented culture materials were put into bag barrels, each bag was loaded with about 1 kilogram, and the wet weight was about 2 kilograms. The compaction is tight and the mouth of the bag is tied with a string. 3. Sterilization: Put the filled bag into a space sterilization package and sterilize it for 4-5 hours, or place it in an atmospheric pressure steamer for 8-10 hours, and cool it until the bag is not hot to the touch. Take it out and set it in a clean room. Third, the hole inoculation: bag temperature dropped below 30 °C hot inoculation. With "four non-type" mushroom sterile inoculator, no electricity, no drugs, no alcohol, no sterilization sterilization. Two people randomly and randomly take the bag to open the hole and inoculate. The punchers placed the material bag on the inoculation inoculation platform, and three holes with a diameter of about 1.5 cm and a depth of 2 cm were evenly punched on the material bag. The vaccinators quickly took the mushroom with the size of the “EX03†mushroom. The plant is planted in three holes. The puncher immediately sealed the hole with a 4 cm 4 cm single-sided plastic tape, and sealed the exposed bacteria in the tube, so that the bacteria could kiss the culture around the hole. After sealing the hole, the material pocket was rotated 180 degrees, and then three holes were punched on the material bag, corresponding to the three holes that had been inoculated. The vaccinators in turn caught the bacteria and planted them into the hole of the hole. The puncher sealed the hole with a tape, and switched it by bag. Connected, set the 15-25 °C clean indoor bacteria culture, open the doors and windows every morning and evening ventilation, check the mycelial growth trend, 7-10 days bag. After 50-60 days of culture, mycelium can fill the whole bag. Fourth, mushroom management: After the mycelium full bag, loosen the bag two tied rope, strengthen ventilation, open the door at night to widen the temperature difference for coloring and budding. When the fungus rod turns from white to tan, and when a large number of nodules are present, the bag tube is removed, and the distance between the bacteria sticks is 3-4 cm upright and leans against the horizontal bar of the plastic arch shed, and the temperature is increased by the coating film. Or remove the membrane cooling method to regulate the seedbed temperature 10-22 °C to keep the soil surface moist. After 8-10 days of culture, the nodules on the bacilli gradually differentiated and spread into fruiting bodies of mushrooms. At this point need to increase the water spray to improve the relative humidity of 85% -95%. When the mushroom bud cover is stretched to 5-10 cm, the edge of the mushroom cap can be harvested when it is not fully deployed. After the first round of fresh mushrooms were harvested, the mushroom sticks were immersed in water to supplement the nutrients, and the management of mushroom cultivation and mushrooming was continued. The 4-5 tides of fresh mushrooms and bioconversion rates were 150%-250%.
