Six Key Technologies for High Temperature Mushrooms

Auxiliary raw materials should be reduced: the formula of wheat bran, rice bran, etc. should be appropriately reduced, can not be used as much as possible, the amount of lime should be appropriately increased to increase the PH value of the culture material, the moisture content of the culture material is generally less, than other seasons The amount of water needed for the cultivation materials is less than 5%. The above requirements are all to strengthen the ability of the culture materials to resist the contamination of the bacteria.

Mixing bagging: in the hot season, the use of bag size is better than the other seasons, so that edible fungus mycelium grow as soon as possible to reduce the bag material pollution, different edible fungi according to their formula will be mixed after the culture material Mix well with water, gypsum powder, calcium superphosphate, etc., and stir it with dry culture material. Mix well with dry culture material and add water. Urea, etc. should be dissolved in water and then mixed with main ingredients. Stir well culture materials immediately. Bags, in hot weather bags, generally require bagging from the beginning to pot sterilization, can not exceed 5 hours, otherwise the culture material is easy to acid and odor, so that the mycelium does not eat material and cause cultivation failure.

Sterilization: The key to sterilization is to ensure that there is a certain gap between the culture bags to facilitate the air circulation inside the stove, so that the temperature inside the stove is uniform, and when the normal pressure sterilization begins, it is to use a high-temperature fire to burn in 2-4 hours. Internally, the temperature in the stove rises to 100 degrees Celsius. If the temperature does not rise for a long time, the bag material will become sour and smelly. When the temperature reaches 100 degrees Celsius, it will be maintained in the middle of the fire for 8 to 12 hours, and the temperature cannot be reduced in the middle. Burn for a while and stop the fire. The sterilizer will add water to the middle of the sterilizer. It is best to heat the water. When the bacterium bag is handled, the temperature of the fungus bag must be handled at about 60 degrees Celsius to control the infection.

Inoculation: The summer weather is hot and humid, and there are miscellaneous insects everywhere. The inoculated environment should be clean and hygienic, and be disinfected and insecticide treated. The vaccinated house (box) should be sealed and sterilized. All tools must be strictly sterilized. In summer, the temperature should be high. To be quick, the amount of strains should be more appropriate than in other seasons. The inoculated bacteria bags should be placed in the shed to be infected.

The germination management: The key technology of the germination management is to properly discharge the stacking bags, timely implement the bag turning and stacking, ventilation and oxygen increase, and control the germination temperature and the ambient temperature. In summer, when the temperature exceeds 30 degrees Celsius, the bacteria bags Must be affixed to a single layer of tiled, strewn to strengthen shading, increase ventilation and heat dissipation, if necessary, splash cold water to promote cooling, the bag internal temperature is strictly controlled at 33 degrees Celsius, with the mycelium The temperature of the bacteria will rise as it grows. Therefore, to intensify the inspection of the inner temperature of the bag pile, it must be borne in mind that as long as the fungus bags have not yet been successfully cultured and enter the management of the Ruru, the phenomenon of burning of the bacteria must be prevented. In summer cultivation, pests (mainly bacillary dysentery) must be strengthened. (Fly flies) precautionary measures, spraying 2000 times of creamy pesticide solution, such as omethoate, beta-cypermethrin, and enemies, etc. to the surrounding environment of the bacteria bag every 4-6 days, can receive obvious pest control, deworming, Insecticide effect. Special attention: Dichlorvos can not be sprayed during germination, otherwise it will cause a large number of mushroom deformities after the mushrooming.

In the high temperature season, premature piling and rising of material temperature can not meet the condition of mushrooming. Mycelium propagation time is elongated and the pellicle is formed. The bacterial rind is too thick, which not only results in the loss of the nutrients of the culture material, but also hinders the hyphae. From vegetative growth to reproductive growth, the mushrooming time is postponed. The budding method in the hot season is to open the greenhouses at both ends of the day and at night, and allow the cold and warm air to directly attack the bacteria bags. At noon every day, the well water is sprayed to the inside and outside of the ceiling film, the space in the shed and the ground to reduce the temperature of the bags. Artificially increase the temperature difference, to promote the formation of bacterial buds, when the mycelium is full of hair, through the hands of the bag rigid and strong, elastic, when the surface of the mycelium is light yellow water secretion or the formation of granular primordium, it is necessary to mushroom .

Mushroom Management: Summer early autumn fruiting, but also separated between each layer of bacteria between the bag with a bamboo pole to prevent the temperature between the bag burning bag, causing the next tidal mushroom or bacterial virus contamination. The water spray time is 10 am and 4 pm respectively. With the development of the mushroom body, the requirements for oxygen and water are also increasing, the amount of water spray should be from small to large, and the opening of the vent should also be From 1/4 to all uncovered and ventilated day and night. Ventilation and water spray management should be flexible and flexible. In the rainy days and foggy days, more ventilation and less water should be used to promote the rapid development of mushroom bodies; if windy weather is encountered, more water should be sprayed to maintain the humidity and properly shut down or reduce. Ventilation in the wind to prevent the mushroom body from dehydrating and drying too quickly. Do not close the vent after spraying water to prevent oxygen deficiency after water absorption by the mushroom body. As a result, nutrient transport is hindered, causing the yellow mushroom to die. Special attention: Close the vent immediately after water spray is one of the causes of yellow mushroom and dead mushroom. In short, during the entire long mushroom stage, there must be a good humidity environment in the shed to keep the air fresh. In warmer seasons, because the bags are separated by bamboo baskets, the mushrooms are also fast.
