Prevention and control of Lentinus edodes
Colored velvet coriander, alias coriander, in classification belongs to basidiomycetes subphylum, hymenomycetes, non-pleated fungi, polyporaceae, coriander genus. Fungus cap leather, sessile, imbricate overlapping, semicircular or shell-shaped, long diameter 1 - 10 cm, short diameter 1 - 6 cm, thickness 1 - 2 mm, cover with narrow concentric rings and slender villi, color diversity, often gray, brown, green to black, shiny, complete or wavy. In nature, it often occurs in the rotten wood of broadleaf trees in summer and autumn. The mycelium growth temperature is 3 - 32℃, the optimum temperature is 25 - 28℃, the optimum temperature for fruit body development is 20 - 25℃, and the relative humidity of air is 85%-90%. This fungus is most likely to infect 2 - 4 years of mushroom wood, from the rainy season to midsummer every year, in poor ventilation conditions, high temperature, high humidity, especially by direct sunlight and dry mushroom wood occurs most. Because of its strong ability to rot wood, mushroom hypha cannot grow once it infects mushroom wood.
After the fruiting body of Coriolus versicolor appears on the Duan wood, it should be removed. Because Coriolus versicolor contains anticancer substances, it has the effect of preventing and treating tumors and improving immunity. It also has certain effect on treating chronic hepatitis. Thus, the excised fruiting bodies are available for medicinal purposes.
Prevention and control methods: in the pile with tree branches and leaves cover, prevent direct sunlight, strengthen ventilation to avoid high temperature, high humidity. Scrape off the fruiting bodies of Coriolus versicolor and smear with 10% lime water or spray with 1% Bordeaux mixture.

The method of preventing and curing the mildew of Lentinus edodes
During the period of changing color and emergence of Lentinus edodes cultivated in bags, the high quality and high yield of Lentinus edodes are often affected by the decay of the mushroom tube. There are two kinds of manifestations of rotten bacteria canister. In one case, the fungus tube is loose and disintegrated. The bacterial tube is loose and inelastic, it is easy to disperse with hand touch, and the culture material has no peculiar smell. It often occurs when the fungus tube is opened to change color or after 1 Mel and 2 batches of mushrooms have been produced. The main reason is that in the process of bacteria propagation in the bacteria tube, the culture room is poorly ventilated and seriously anoxic, or a certain bacterial temperature is produced in the later stage of mycelium growth, coupled with high air temperature, and the heap is not turned in time to dissipate heat, resulting in a part of the temperature exceeding 35 ℃.

Measures to prevent the difficulty of mushroom production from bag material
In recent years, the "Xixia Model" of cultivating mushroom with plastic frame has become a model for the northward migration of mushrooms from south to north in China, blooming all over the country. However, due to the regional climate temperature difference and the lack of understanding of mushroom varieties and fruiting characteristics in newly developed areas, the use of medium temperature mushroom varieties, such as 135,241,939,L26, etc., or the same type of strain, in the low temperature season to promote the mushroom, there will be abnormal phenomenon that the mushroom cannot normally produce, light will reduce production, heavy loss. Now we will control the bag material
