Cultivation techniques of Lentinus edodes in summer

First, mushroom arrangements: generally seed production in early February, bagging and sterilization in late April, mushroom production in early August, and harvest in early November. Second, variety selection: select high temperature tolerant varieties, we choose Suxiang 1, 1310 and other varieties. Third, the cultivation place: the cultivation place should be as cool and moist as possible. Use the greenhouse or under the high-yielding forest, hillside and other places to use a small arch shed for production, the greenhouse above the sunshade net, or in front of the shed planting towel gourd, wax gourd and other climbing crops. 4. Cultivation management: ① formula: sawdust 80%, wheat bran 18%, sugar and gypsum 1% each, material-water ratio 1. 2%; sawdust 20%, corncob 60%, wheat bran 15%, cornmeal 4%, gypsum 1%, material-water ratio 1. 25% 1.35. ② ingredients: raw materials are screened, wood blocks and other hard objects are removed to prevent piercing the bag. Weigh according to the formula, turn and mix well. Don't have too much wheat bran. Too much bran is easy to sour the material. After that, sprinkle the dissolved sugar water and water into the material and mix well. After that, it is best to bag within 2 hours to prevent rancidity. When the temperature is high, 0.1% carbendazim or mildew king can be added to the material. ③ bagging: adjust the prepared material to pH6~6.5 with lime water, pack and compact immediately after absorbing enough water, or use a bagging machine. The bacterial bag is made of high-density and low-pressure polyethylene film with length × width × thickness of 50cm × 60cm × 15cm × 17cm × 0.05mm. ④ sterilization: immediately after bagging, the pot should be sterilized, and the material bag should be put neatly, preferably in a turnover basket. First attack with a big fire, reaching 100 ℃ in 2-3 hours, lasting 8-10 hours, and then gradually cool down. ③ inoculation: the sterilized bacterial bag was moved into the inoculation room and stacked in the shape of a "well". When the temperature dropped below 28 ℃, it was inoculated. Before inoculation, all appliances in the inoculation room should be disinfected with smoke disinfectant; bacteria bottles, bag surfaces and operators' clothes and hands should be sterilized with 75% alcohol. The inoculation block should be kept intact as far as possible, and the mycelium could germinate and survive. The speed of vaccination should be fast, and the amount of inoculation should be sufficient; the inoculation room should avoid people walking and talking as far as possible; the time of vaccination should be in the morning and evening. ⑥ bacteria: after inoculation, gently move the bacteria bag indoors, such as bacteria in the shed, disinfection before use, the ground is sprinkled with lime powder. Air is ventilated in the morning and evening when the temperature is high and at noon when it is low. Pour the bag once every 10 days, check the mycelium growth, change the position on top, middle and bottom, and handle it gently. If miscellaneous bacteria are found to be less than 5 cm, you can use 95% alcohol or 20% formaldehyde injection, hand massage to make the medicine infiltrate, seal with adhesive tape; serious pollution should be isolated and treated. With the growth of mycelium, it is necessary to keep an eye on the growth of mycelium and increase oxygen. Pay close attention to the germicidal temperature and adjust the stacking level as appropriate. ⑦ bag removal: the best time for bag removal is 10-15 days after full bag, generally from the time of inoculation, 60-65 days for early-maturing varieties and 80-90 days for middle-late-maturing varieties, and the hyphae are light yellow. ⑧ mushroom stimulation: move the bacterial stick after taking off the bag to the shed where the bracket is fastened, put it vertically on the ground, and set up a small arch shed on it, and cover it with plastic thin touch to protect moisture and pay attention to sunshade. When Jie Lei occurs, we should strengthen ventilation and increase sprinkler irrigation every day.
