Technical Model of Pleurotus eryngii Factory Cultivation
1. Main cultivation technology models
The industrial cultivation technology of Pleurotus eryngii is aimed at the production of fresh mushrooms for sale, adopts industrialized technical means, and realizes the large-scale, intensive, standardized and annual production of Pleurotus eryngii under controllable environmental conditions.
2. Supporting technical points
(1) Cultivation season. Mushroom bags are made from early February to mid-March, and mushrooms are produced in June to October, and the cost of mushroom production is low. Factory production is mostly annual production.
(2) Strain selection. Select strains with strong stress resistance, strong resistance to miscellaneous bacteria, robust mycelium growth, fast fruiting body growth, high quality and high yield.
(3) Grow bag making.
Culture medium formulation. Formula 1: 48% corn cob, 20% sawdust, 25% wheat bran, 5% corn flour, 1% gypsum, and 1% lime. Formula 2: miscellaneous sawdust 20%, corn cob 30%, bean straw 20%, wheat bran 25%, corn flour 3%, gypsum 1%, lime 1%.
Prepare materials. Wheat bran, corn flour, gypsum, lime and other auxiliary materials are fully prepared and properly kept to prevent mildew and loss.Culture medium formulation. Formula 1: 48% corn cob, 20% sawdust, 25% wheat bran, 5% corn flour, 1% gypsum, and 1% lime. Formula 2: miscellaneous sawdust 20%, corn cob 30%, bean straw 20%, wheat bran 25%, corn flour 3%, gypsum 1%, lime 1%.
Mixing. Weigh the qualified materials according to the formula ratio requirements, add water to pre-wet while stirring the main ingredients, add wheat bran and gypsum half an hour before bagging, and mix evenly, the water content is 63%~65%, adjust the pH to pH7.5 with lime.
Charge. Generally, high-pressure polypropylene plastic bags with a thickness of 17 cm x 33 cm and a thickness of not less than 0.04 cm are used. The height of the material is 18 cm. It should be dense and moderate. Tighten the top and loosen the bottom. Level the surface of the material and compact it. A hole with a diameter of 2 cm is drilled in the middle of the material, and the depth is two-thirds of the height of the material. Put on the collar and stuff with cotton or cover with a cotton-free cover.
Sterile inoculation. Autoclave sterilization at 125°C (0.12 MPa pressure) for 2 hours, and take out the pot when the temperature drops below 60°C. Move the sterilized bacteria bags directly into the pre-sterilized cooling room, cool down to below 28°C and wait for inoculation.
Mycelium culture. After the inoculation, move the bacteria bags to the sterilized bacteria cultivation room to grow bacteria away from light. The temperature of the culture room is kept at 20°C~22°C, and the relative humidity of the air should be kept below 70%; ventilate once or twice a day. Check the cultivation bag pollution 7 days after inoculation, and clean up the bacteria bag contaminated by miscellaneous bacteria in time. Thereafter, check every 10 days. After 30-35 days of cultivation, the mycelium is covered with fungus bags, and moved to the fruiting room for fruiting management.
