Overwintering management technology of Lentinus edodes bag
After entering the Winter Solstice, the temperature will drop obviously. This paper puts forward the following technical suggestions on how to do well the overwintering management of Lentinus edodes for mushroom farmers' reference:
1. Remove the sunshade net used for cooling and thermal insulation, and let the sunlight shine directly on the plastic greenhouse to increase the daytime temperature of the greenhouse.
2. Reduce the number of ventilation around the greenhouse, change the steam every other day, and the small arch film in the greenhouse generally does not need to lift the film ventilation except picking Lentinus edodes.
After the end of a tide of mushrooms, let the bag dry and ventilate for 10 days, and then inject Cui Lei, Cui Lei period pay attention to heat preservation. If the temperature in the mushroom shed does not exceed 15 degrees, it can be ventilated once every 5 days in 3mi, and the existing mushrooms can be ventilated in combination with Lentinus edodes.
For high-temperature varieties such as L26 and Qingke 20, it is difficult to grow when the temperature drops below 10 degrees, so we should pay attention to heat preservation and proper ventilation to prevent bacteria bags from spending the winter in high humidity.

Bag cultivation techniques of Lentinus edodes
1. Raw material preparation (1) Wood slices with a moisture content of more than 20% are inserted into the feed port of the slicer and cut into fragments with a thickness of about 4 mm and a cross section of 60 × 20 mm. (2) crushing the raw materials put the sun-dried wood chips or bagasse, Camellia oleifera shell and manuscript stalks into a special grinder or feed grinder (a special iron sieve with a sieve hole of about 2mm) and process it into powder. 2. Preparation of culture materials (1) Culture ratio of main materials such as sawdust, bagasse, etc.

Treatment measures of Lentinus edodes bag pollution
The bacterial bag should be turned 4-5 times during indoor culture, the first time at 6-7 days after inoculation, and then every 7-10 days. Check the miscellaneous bacteria carefully when turning the bag and deal with it in time. Only sporadic or filamentous colonies of miscellaneous bacteria appear at the mouth or folds of the bacterial bag with mild pollution. If there is no spread, the injection syringe can absorb 50 ml of 75% alcohol and 30 ml mixture of 36% formaldehyde, inject the injured area, and gently massage the surface with fingers to soak the liquid into the body of miscellaneous bacteria, and then stick the injection mouth with adhesive tape. Inoculation hole contaminated miscellaneous bacteria
