The Problem and Treatment of Edible Fungi Growth in Low Temperature Season

There are two reasons why young mushrooms do not differentiate: First, the temperature of the shed is low, which is not suitable for the development and differentiation of young buds. The treatment method can be solved by raising the shed temperature; secondly, some pesticide farmers use a large amount of pesticides and spices. During spraying, pesticides are also sprayed to prevent the occurrence of diseases. As a result, the waste gas in the bag is heavy and the mycelium is inhibited. 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 reason why the young mushroom is slow is that the temperature of the greenhouse is too low, or the selected strain is not suitable for the current temperature. Treatment methods: increase the temperature of the greenhouse, first, install the greenhouse water temperature air conditioner, the temperature is arbitrarily adjustable, even if the selection of medium-high temperature strains can also be normal mushroom; Second: install soil heating, pay attention to the point is that the chimney must be smooth, And to maintain sufficient amount of air intake, so as to avoid shortage of oxygen in the shed; Third, the drying shed, black plastic film or high-density shade nets shall be set up at the top of the shed, and the volume shall be drafted. The heat inside the shed will not enter the light, and the effect is good. However, rain and snow cannot warm up. 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 of plastic pipe to the 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. The larvae of burr bacteria on the lid of the burr have some wormy meat tissue that affects the quality of the mash. The main reason is that the shed temperature is low, or the strain is not a true low-temperature type, such as the 2006 strain, even if the temperature is below 0°C, no burr occurs. Such malformation mushrooms, this is the real low-temperature strains, processing methods: warming and heat preservation. Cauliflower sprouts and stipe in the former are not differentiated in mushroom buds, while the latter is indifferent in the structure of capsella. The main reason is the high concentration of carbon dioxide in the greenhouse and the lack of oxygen supply. Treatment method: Strengthen ventilation. The main reason for the upturned trumpet shape of the cap was that there was drug effect, poor ventilation, degeneration of the strain species or the temperature 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 differentiate”; 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. The main cause of aerial hyphae exuberance is the imbalance of carbon and nitrogen ratio, excessive nitrogen, and the treatment method: spray lime water on the surface of the material at a concentration of about 5%, or use lime water to impregnate the bacteria bag to decompose nitrogen and make it as soon as possible. Achieve assimilation level, strengthen or strengthen ventilation at the same time, make aerial hyphae fall down as soon as possible, kinks and buds; 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 pheromone should be added to avoid this. The phenomenon of class. The basic cause of thick fungus is the same as above, but it takes longer. In addition to the unbalanced nutrition of the base material and the misalignment of the carbon and nitrogen ratio, the temperature of the strain does not meet the current temperature and other reasons. In addition, the base material contains unknown substances, especially pesticides, which produce hyphae. Suppression leads to no mushroom. Treatment method: Refer to the above treatment using lime aqueous solution. The fruiting body of the fruiting body has “pilus” at its base, and the mushroom product is not exactly correct. The main reason for the low quality of the product is that the base has “pilus”, which is a white mycelium, and some are due to poor ventilation, high humidity, and the growth of edible mushrooms. Hyphae, and some are fungal infections, the early performance of the mycelium, once the temperature rises, it will develop as a disease, such as brown rot, that is the performance. 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.
