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. The inoculation point pollutes the inoculation hole, but the mycelium is still in the growth stage, and the bag which has little effect on the mycelium growth of Lentinus edodes can first use 5%-10% lime water supernatant, and then wipe the affected area with 50% carbendazim solution, but avoid applying to the mycelium of Lentinus edodes. If dead bacteria are found, they should be re-inoculated under aseptic conditions. Seriously contaminated bacteria bags are basically covered with miscellaneous bacteria flower spots, should be broken bags to take materials, mixed with 3% lime solution piled overnight, spread out and dried, re-ingredients, bagged sterilization, and then inoculated and cultured.

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 a good job in the overwintering management of Lentinus edodes for mushroom farmers' reference: 1. Take off the sunshade net originally used for cooling and thermal insulation, and let the sun 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. Inside the mushroom shed

It is important to change the color of Lentinus edodes sticks
When the mycelium of Lentinus edodes fills the bag and reaches a certain physiological maturity, the ventilation, light, temperature and humidity of the growth environment are artificially regulated, so that all the aerial hyphae on the material surface lodge and secrete pigments. the color of the material surface gradually changed from thick white and light white to light brown to brown and brown, and finally formed a brown membrane with multiple functions such as heat preservation, moisturizing, light protection, anti-miscellaneous bacteria and so on. This process is called color conversion. The color depth and film thickness of Lentinus edodes stick are closely related to the time, yield and quality of mushroom. General condition
