Reasons for the death of greenhouse mushrooms Mushroom mushrooming often occurs when the mushroom shrinks and turns yellow and dies. The main reasons are as follows: 1. Continue high temperature. The temperature in the fruiting stage is higher than 23 °C for more than 3 consecutive days. The growth of the bud is inhibited by the temperature, which is conducive to the growth and development of the hyphae, so that the nutrients are reversely transported, resulting in the buds being dead without nutrition or moisture. Therefore, after the mushroom is produced, it is still necessary to prepare for high temperature resistance, such as using a shed on the south side, spraying water on the surface of the mushroom house, or cooling the ice block and appropriately delaying the stacking, avoiding the high temperature and the like. 2. Insufficient nutrients. There is not enough nutrient supply in the culture material, such as insufficient nitrogen source in the pile, especially the lack of manure, the carbon-nitrogen ratio is out of balance, the accumulated culture material is anaerobic fermentation, the culture material is thin and less, the nutrition is insufficient, or the mushroom nutrients are exhausted, resulting in spring. Mushrooms are folded. Therefore, it is required to provide high-quality materials, fermented yeast, turn over good materials, and promote thick material cultivation to provide sufficient nutrients. 3. The mushroom house or mushroom shed is poorly ventilated. The mushroom house is depressed, and the ventilation is poor for a long time, especially in the mushrooming stage. The fruiting body metabolism is strong, such as the high temperature and high humidity caused by the water in the window, which causes a large number of fruit bodies to die. 4. Improper water management. The requirements for water in different growth stages of fruiting bodies are different. The lack of water in the bacteria layer and the lack of sufficient water supply in the soil layer can also cause the death of the young buds, or the water is not clean, and the long-term spray of water will cause death. 5. The osmotic pressure is too high. Repeated use of saline will increase the osmotic pressure, causing the bud to lose moisture and die. 6. When the pests are seriously harmful, they will eat the hyphae, causing the buds to die in batches. 7. Abuse of pesticides. The pesticide used during the mushrooming period should be diluted as required. Increasing the concentration of pesticides at will causes phytotoxicity, and the use of pesticides containing petrochemical emulsifiers is prohibited. Management considerations Mushrooms need water, but mushrooms are afraid of water, because more water will damage the hyphae, causing the mushroom to reduce production. Different stages of fertility vary. In addition to the use of water, the management of greenhouse mushrooms also needs to pay attention to the following points: 1. Prevention of pests and diseases Pests and diseases have a great threat to mushrooms. Once they are harmed, they will endlessly suffer, and some will even end up. The focus of pest prevention is: the culture material should be killed before entering the house, the secondary fermentation should be emphasized, and the mushroom house should be disinfected and disinfected beforehand. The strain should be fumigation with aluminum phosphide, and the soil should be covered with formaldehyde, lime or Fusarium, and mold. Spirit processing, daily mushroom room often spray pesticides. 2, prevention of free ammonia Ammonia has a toxic effect on mycelium, which makes the sowing species lose their vitality. It was found that the culture material had an ammonia smell, and the next species should be stopped, and the ammonia treatment was carried out with formaldehyde. The amount of formaldehyde depends on the amount of culture material and ammonia content, and then fumigation and then turn to flat. Generally, as long as the carbon-nitrogen ratio of the ingredients is paid attention to when stacking, the nitrogen fertilizer should not be used too much, and the chemical fertilizer should be controlled in an appropriate amount. When the nitrogen fertilizer is put into use at the time of stacking, the production of free ammonia can be avoided. Disclaimer: Some articles on this website are transferred from the Internet.
