TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: In the step (i), the mixed pre-wet cultivation material comprises 15% sawdust, 36% corn cob, 15% bagasse, 20% bran, 5% corn powder, 5% soybean meal, 2% calcium carbonate and 2% calcium oxide. Preferred Method: In the step (i), the pre-wetting with stirring operation includes mixing the cultivation material by using pre-wet mixer with stirring for 5 minutes, and then taking a microcomputer time controller, electromagnetic valve and pressurizing water pump, according to required amount, and stirring for at least 15 minutes to obtain mixed cultivation material. In the step (ii), polypropylene bag of 18x 35x 0.005 cm is used as a packaging bag, where each polypropylene bag is added with 1200-1300 g mixed cultivation material. In the step (i), the pre-wet process comprises stirring, and packaging for not greater than 2 hours. The step (iii) comprises carrying out steam sterilization for first time under vacuum of 0.055 MPa at 100 degrees C, and maintaining the sterilized cultivation bag at 30 minutes, then sterilizing again by using steam at 110 degrees C, and maintaining for 20 minutes, then sterilizing using steam at 125 degrees C, and maintaining for 3 hours, and then sterilizing at a vacuum degree of 0 MPa, and taking out the cultivation bag. The step (vi) comprises cultivating Pleurotus eryngii added into the cultivation bag in a room to carry out fruiting management which is divided into primordia promotion period, mushroom bud forming period, elongation period and mature period management, and then adding ground water during primordia promotion period to maintain room humidity at 90-95%, maintaining the carbon dioxide concentration in the room at 0.3-0.5% during mushroom bud forming period, and taking artificially produced buds with sparse, cutting the poor quality mushroom with a knife, where each cultivation bag is added with 1-3 mushroom buds, and maintaining the carbon dioxide concentration in the room at 0.4-0.6% during elongation period, and maintaining the carbon dioxide concentration in the room at 0.4-0.6% during mature period. The step (vii) comprises allowing the formation of Pleurotus eryngii smooth cover, without ejecting the spores, and recovering under controlled period of 17-20 days, cleaning the recovered mushroom house, sterilizing, ventilating for 1-2 days, and then packaging, and chopping off the base of Pleurotus eryngii placed in a cultivation medium by using a stainless steel knife, and placing in a cold library at 2-5 degrees C for 4 hours, and cooling to protection freshness in the package. The step (vi) comprises illuminating the cultivation bag in mushroom room in presence of diffusion light, for 8-10 hours/day or 24 hours/day.
