Causes and Countermeasures of Death of Straw Mushrooms
Reasons and Countermeasures for Death of Straw Mushrooms During the mushroom hatching, mushroom buds often appear shriveled and eventually die. There are many reasons for the death of Mushroom mushrooms. Mushroom farmers should focus on prevention. 1, improper use of water. In the high temperature conditions, a lot of water, so that the young mushroom bud surface covered with a layer of water film, respiratory metabolism was blocked and wilting dead mushrooms. Especially in the case of poor ventilation and high carbon dioxide. Countermeasures: (1) The moisture content of culture materials is adjusted at one time, and the water is only sprayed into the air, the ground, and the surrounding areas when the mushroom is grown. 2 When spraying water, make air convection as much as possible. After spraying, it is not appropriate to tightly cover the film immediately to prevent boring of young mushrooms. 2, young mushrooms too dense. Sowing volume is too large, ventilation and ventilation is too small, young mushroom bud is very dense, in which the ability of large mushroom buds to absorb nutrients is strong, and some small buds died due to lack of adequate nutrients. Countermeasures: 1 Suitable for sowing. 2 pay attention to ventilation. 3 Make up for fine soil to prevent the mycelium from growing out of the soil, and push down the part of the mushroom to prevent it from becoming too dense. 3, inappropriate mushrooms. When harvesting 1-2 tidal mushrooms, because of careless action, the mycelium of the buds was shaken or broken, and they lost their ability to absorb water and nutrients and died. Countermeasures: Be easy to move when harvesting, be careful not to damage the surrounding mushrooms. 4, drug death mushrooms. In the prevention and treatment of diseases and miscellaneous bacteria, improper use methods, will cause dead mushrooms due to phytotoxicity. Countermeasures: Do a good job of sterilizing and killing insects. The dosage should be accurate and the spray should be uniform. Avoid heavy spraying. 5, excessive carbon dioxide. When mushrooming, the mushroom house is poorly ventilated and lacks oxygen. In addition, the mycelium breathe vigorously, the heat produced cannot be distributed quickly, and the young mushrooms die sultry. Countermeasures: Open doors and windows or turn off membrane ventilation in time to cool down and prevent heatstroke.
