The optimum temperature for the growth of mushroom mycelium is 24°C-26°C. When the outside temperature is higher than 35°C, the growth stops and the production cycle is longer. Mycelial culture needs to pass through the hot summer, and the management is not good. A lot of bacteria bags infect bacteria, which can easily cause bad bags. At present, the mushroom production has entered the preparatory stage of summer. According to the observations and experiments in recent years, the author had the following experience in the safe summer of fungus tube for the reference of the majority of edible fungus producers.
1. Suitable for summer facilities. According to the temperature requirements of mycelium growth, cool, ventilated and rain-proof places should be selected. The temperature of the culture room should be controlled below 30°C, and the maximum temperature should not exceed 33°C. For example, bungalows, auditoriums, warehouses, etc. of civil engineering structures can also be used. Shade the summer outdoors, but don't put any houses on the top floor of the special mix structure and under the platform over the summer.
2. Place the fungus tube. The summer tubers are placed in the form of “goods†or “wellsâ€, “△†shapes, and scaffoldings. The purpose is to expand the contact area between the fungus tube and the air, so that the heat in the seedling tube can be distributed in a timely manner to facilitate the ventilation of hyphae. .
3. Control the temperature and prevent high-temperature burning bacteria. The cultivation room doors and windows are covered with straw or shade nets to prevent direct sunlight. A thermometer should be placed in the middle of each culture chamber. Every day at noon and evening, the maximum temperature should not exceed 33°C. In the hot season of July-August, it is possible to reduce the temperature in the channel by watering. It is forbidden to move the fungus tube to prevent it from being rotted.
4. Puncture ventilation in time. The purpose of the tube puncture is to ensure that the mycelium in the tube can breathe normally, reduce the moisture content of the culture material, increase the gap of the mushroom, promote the accumulation of nutrients in the mycelia, inhibit the generation of nodular projections, and prevent bacteria Barrels are bad.
5. Discharge yellow water in a timely manner and turn off the color of the fungus tube. When the temperature rises during the summer time when the fungus tube rises and yellow water appears in the bag, the nail film is used to pierce the yellow film, but the bacterial bag cannot be squeezed by hand, otherwise the fungus may be broken and easily infected by the bacteria causing the bag to be damaged.
