Straw mushroom is a high-temperature, constant-temperature solid fungus with strict requirements on the environment. According to the biological characteristics of the straw mushroom and the author's experience in the practice of straw mushroom cultivation and cultivation for many years, the causes and countermeasures of the straw mushroom were discussed for readers' reference.
I. Causes of Death of Mushrooms
1. Mushroom ventilation and moisturizing are not coordinated. Straw mushroom is an aerobic fungus, which requires a lot of water for growth, and it is easy to dry out due to excessive ventilation. Insufficient ventilation can cause excessive carbon dioxide and death due to lack of oxygen.
2. The mushroom house temperature suddenly changes. Most of the straw mushroom cultivation in the south uses foam mushroom house, which plays an important role in constant temperature and humidity. However, if typhoons were not used to close windows and doors in time, or if they were not heated in time when they were frozen, they could not be ventilated and cooled early in the event of sustained high temperatures, or the well water that was sprinkled on the floor was excessive, and the cooling was too fast. Can not stand the sudden change in temperature and die in batches.
3. Poor quality and disease and insect damage. For various reasons, age-appropriate strains die of ageing because they cannot be cultivated in time. The vigor of the mycelium is poor, and the accumulation of nutrients after seeding is insufficient, and the survival rate of the mushroom will be very low. At the same time, dead mushrooms may also appear when infected with bacteria or by locust infestation.
Second, prevention and control measures
1. Straw mushroom grows in high temperature and high humidity environment. After cultivating the material into the house, it is necessary to strictly control its water content and eliminate the use of over-age strains. At the same time to maintain the temperature of the mushroom room at about 30 °C, if you encounter continuous high temperature weather, when the water is too little, you can spread water to the floor and increase ventilation and ventilation to achieve the purpose of cooling and moisturizing.
2. The application of wheat bran (nitrogen) on the surface of bacteria should not exceed 3% (or not), so as to reduce the occurrence of green mold and other bacteria and insect pests.
3. Be careful when harvesting straw mushrooms so as not to mechanically injure the mushrooms or break the layer of mycelium causing dead mushrooms. As long as care is taken at every production stage, the death mushroom phenomenon in mushroom cultivation can be reduced.
