In the cold season, it is the main fruiting season for edible mushrooms. However, during the annual freezing season, there will be some problems in the production of edible fungi. The major problems this year are manifested in four aspects:
One, young mushrooms do not differentiate, long slow
Mushroom buds are difficult to differentiate in the later period: According to the situation reflected, the author analyzed that the main problems are two aspects: First, the greenhouse temperature is low, not suitable for young bud development and differentiation. Can be solved by increasing the temperature of the greenhouse; Second, the impact of drugs, such as some farmers use a lot of pesticides and spices, spraying pesticides during germination, to prevent the occurrence of diseases, resulting in heavy waste bags, and even the occurrence of mycelium inhibition.
Treatment method: After destroying the material surface, spray 6% lime aqueous solution twice a day, for 2 to 3 days, and calm the bacteria. When the buds emerge again, they can be managed normally; if the drug concentration is high, Need to take lime water soaked bag approach to be resolved.
The slow speed of the young mushroom is mainly due to the low temperature of the greenhouse, or the selected strain is not suitable for the current temperature. The treatment method is to increase the temperature of the greenhouse. There are three main ways: First, install a greenhouse water temperature air conditioner, the temperature is free to adjust, even if the selection of medium-high temperature strains, can also be normal mushroom; Second, install the soil heating, pay attention to the point is that the chimney must be smooth, and to maintain Adequate amount of air intake to avoid shortage of oxygen in the shed; Third, the sun. A black plastic film or high-density shade net is pulled up at the top of the booth. The volume is drafted and the heat inside the booth is not allowed to enter into the light. The effect is good, but rain and snow cannot warm the weather. There are low-pressure furnace cultivation households, can be "Little White Dragon" in the shed against the wall and placed in a circle, and finally received the boiler, boil the steam after the continuous transmission to the plastic pipe, mushroom shed heating, the effect is very it is good. If it is a medium-high temperature type strain, and no power can be warmed up, it can cool down and reduce humidity, and when the temperature rises, it will be re-emerged.
Second, the burr cap, cauliflower, crude stipe, mushroom cap upturned trumpet and other malformation mushrooms
The burr on the vegetative cover is the occurrence of some wormy meat tissue on the vegetative cover that affects the quality of the mashroom product. The main reason is that the shed temperature is low, or the strain is not a true low-temperature type. If the true low-temperature strain 2006, even below 0°C, it will not Malformed mushrooms such as burrs occur. The treatment method is warming and heat preservation.
Cauliflower calyx, coarse stipe, the former is the mushroom bud does not differentiate, the latter is the cap tissue does not differentiate, mainly due to the high concentration of carbon dioxide in the greenhouse, the lack of oxygen supply. The treatment is to enhance ventilation.
The mushroom cap tilted up like a trumpet, mainly due to drug effects, poor ventilation, strain species degeneration, or the temperature profile of the strain did not meet the conditions of the time period. Treatment method: If there are chemical drugs in the base material, please refer to the treatment method of “do not differentiateâ€; when the ventilation is bad, ventilation should be carried out at noon during sunny weather; if the species is degraded, it cannot be cured, and the temperature of the strain is not. Suitable for this season, can be taken to solve the solution.
Third, the aerial hyphae are very vigorous, thick bacilli, not mushroom
The aerial hyphae are prosperous. The main reason is the imbalance of carbon and nitrogen ratio and excess nitrogen. Processing methods: spray lime water on the surface of the material at a concentration of about 5%, or use lime water to soak the bag of bacteria and decompose nitrogen to make it as soon as possible. Achieve assimilation level, strengthen or strengthen ventilation at the same time, make aerial mycelium lodging and budding as soon as possible; in the future production, attention should be paid to the deployment of base nutrition so that it can be fully balanced. In particular, three-dimensional spermatozoa should be added to avoid this category. The phenomenon occurs.
Thick bacilli, the basic reason is the same as above, but it takes longer.
In addition to the unbalanced nutrition of the base material and the imbalance of carbon and nitrogen ratio, there are strains whose temperature type does not meet the current temperature and other reasons. In addition, the base material contains unknown substances, especially pesticides, on the mycelium. Inhibition occurs, resulting in no mushrooms. Treatment method: Refer to the above treatment using lime aqueous solution.
Fourth, the sub-entities have "pilus" at the base of the fruiting body.
The base has “pilusâ€, which is white mycelium, and some are because of poor ventilation, high humidity, aerial mycelium grown by edible fungi, and some are fungal infections. The early stage is mycelial, once the temperature rises. It will develop into a disease, such as brown rot. Treatment method: After clearing the material surface, spray about 400 times the silly solution, reduce the humidity, observe no more than a week to develop, you can switch to normal management.
Ciprofloxacin is a broad-spectrum antibiotic that is active against Crampositive.Gram-negative bacteria, Myco plasma infection, Ecoli, Salmonella, Anaerobic bacterobic infection and Streptocossus, etc.
It is used for treatment of bacterial infection and Myco plasma infection in livestock and Poultry.
and also used for gastrointestinal, respiratory and urinary tract infections caused by ciprofloxacin sensitive micro-organisms like Campylobacter, E. coli,Haemophilus, Mycoplasma, Pasteurella and Salmonella spp. in calves, goats, poultry, sheep and swine.
