Prevention and treatment of non-growth of mushroom hyphae
After sowing for about 10 days, the mushroom hyphae can obviously grow into the material, if not, it is because the culture material is wet and thick, the material is dry, the material layer is hardened and so on. It is necessary to find out the cause in time to create good conditions for mycelium growth. Although the material surface is dry, do not spray water on the bed when cultivating mycelium. If the material is too dry, you should replenish the nutritious water in the material, about 90 kg of soybean bubble swelling grinding juice for every 100 square meters, add 45 tablets of yeast, 127 tablets of vitamin B127, 0.45 kg of sugar, mix and dissolve in the sprayer, remove the sprinkler, replace the water injector and insert the middle layer of the culture material at a distance of 15 cm on the bacterial bed, inject the right amount of nutritious water, and create suitable water and nutritional conditions for the mycelium to grow downward. If the material layer is wet, thick and hardened, it can pry loose the culture material, distribute water, eliminate waste gas, increase the air permeability in the material, and promote the downward growth of mycelium.

Control of common diseases and insect pests of Lentinus edodes
In the process of Lentinus edodes production, it is often harmed by diseases and pests. If the prevention and control is unfavorable, it will make the cultivation of Lentinus edodes fall into a vicious circle. If it is light, it will reduce the yield, and if it is serious, the cultivation will fail. Therefore, great attention must be paid to it. Trichoderma, also known as green mold, is widely distributed in a variety of plant residues, soil and air. Trichoderma spreads by spores and invades the culture medium with the aid of airflow, water droplets, insects, raw materials, tools, hands and clothes of operators, and germinates and propagates as soon as the conditions are suitable. When the production environment is not clean and the culture material

Control of mushroom powdery mildew
Powdery mildew is caused by Monosporium roseum infection and is transmitted by soil cover, airflow and water. It occurs seriously under the condition that the culture material is wet. The symptoms are white villous hyphae at the beginning of the cap, followed by pink powder mold. When the disease is serious, the red powder mold is very thick, the fungal folds are red and pink, and the mushroom body is stiff and dry. Prevention and control measures: strengthen ventilation and control the water content of soil cover and culture materials. Spray 500-fold carbendazim solution and 800-fold topiramate solution in the ward.
