Prevention and control of several common diseases of straw mushroom

Today I will tell you about the prevention and treatment of several common diseases of straw mushrooms:

1. The mushroom buds wither

① The temperature should be controlled at 25-28℃ during the mushroom bud formation period. When the temperature drops below 20℃ in early autumn, cover the shed with straw curtains to keep warm; ② The light should be dim during the growth stage of the fungus line to prevent strong light stimulation and premature formation of mushroom buds; the straw should be compacted to facilitate the close connection of the mycelium; ③ During the mycelium growth period, spray the culture medium around the mushroom bed with dervine essence and dichlorvos to kill pests such as millipedes and woodlice; ④ The fungus species must be separated or introduced every year and stored at a suitable temperature; ⑤ Regularly sprinkle water on the ridges around the material blocks or in the furrows. ⑥ After the mycelium has grown all over the culture medium, remove the film covering the surface of the culture medium in time to ventilate the room, but avoid the wind and dry wind blowing directly into the mushroom room, so as to combine heat preservation and ventilation; ⑦ Before cultivation, the culture medium should be exposed to the sun for 1-2 days, and the pH should be adjusted to about 8-9 when mixing the ingredients; ⑧ When picking mushrooms, do not pull them hard to avoid hurting the young mushrooms. After picking, clean the mushroom bed, dig out the mushroom heads, and pick off the rotten mushrooms.

2. Young straw mushrooms shrink and die

① This situation cannot be remedied. The only feasible way is to purchase the appropriate-age strains, that is, healthy strains within 3 days of age; ② Control the temperature change well, and the amplitude should not be too large. Do not spray water on the mushroom bed when the mushrooms are forming; ③ The materials should be fermented and sterilized before entering the bed. If there are mites on the bed, spray 0.1-0.2% dichlorvos when the mushrooms have not yet grown, and cover with a film.

3. Prevention and control of fungi such as Coprinus comatus

① Choose fresh, clean and mildew-free culture medium;
