Perhaps in the eyes of others, it is very difficult to say goodbye to Flammulina velutipes and blackheads. In fact, as long as it is done with the following requirements, it is not difficult. First of all, it is necessary to keep the mushroom farm clean and clean. Mushrooms and waste; mushroom house, bed frame, utensils, etc. should be thoroughly disinfected with 1:50 times of Venus disinfectant or 2% bleaching powder, especially the mushroom shed with serious disease .
When mixing, the mixture should be mixed with water at a ratio of 1:1000 times. High-toxic, high-residue antifouling agents should not be used to ensure the production effect;
When the Flammulina velutipes is cultivated, the culture material should be thoroughly sterilized. When the mushroom and the mushroom are cultivated, the culture material should be fully fermented, the rot is evenly cooked, and the soil covering material can be fumigated with formaldehyde.
During the mushrooming period, the temperature of the mushroom is controlled to be below 15°, avoiding the high temperature and high humidity season. When the temperature is high, the ventilation and heat dissipation should be strengthened. The temperature of the mushroom should not exceed 18°. If the temperature suddenly rises, the temperature should be lowered. Measures, such as opening windows, uncovering the film, shading, etc., but pay attention to the temperature fluctuations in the mushroom house should not be too large, to prevent condensation of water vapor, resulting in water film.
Found that the diseased mushrooms should be removed in time, and immediately increase the amount of ventilation, suspend or reduce water spray, quickly reduce the temperature, and medication to control the degree of disease, such as spraying 5% lime water solution to the surface, can also spray per milliliter oxytetracycline solution or streptomycin 300 units units 100-200, or 500-1000 times the bleach solution, once every two days, one day before and after spraying Guchuang without water, with an interval of 3-4 days again pesticide , continuous use more than 3 times, can effectively control the spread of disease. When the disease is serious, the diseased mushroom should be removed first, and the surface or soil should be cleaned and then sprayed as described above.
