A probe into the death of Straw Mushroom and Young Mushroom

In the process of straw mushroom production, it is often seen that pieces of small mushrooms wither and die, which brings serious loss to straw mushroom yield. There are many reasons why young mushrooms die, mainly the following. 1. When pH value is less than 6, although it can bear fruit, it is difficult to grow. Acidic environment is more suitable for the growth of green mold, yellow mold and other miscellaneous bacteria, competing for nutrients causes the death of straw mushroom. Therefore, when preparing the culture medium, the pH value in the medium should be appropriately increased. After picking the first mushroom, spray 1% lime water or 5% plant ash water to keep the pH value in the material around 8. 2. The mushroom growth is very sensitive to temperature. Generally, when the material temperature is lower than 28 degrees Celsius, the mushroom growth is affected or even died. If the temperature changes too much, such as cold wave or typhoon attack, it will cause a sharp drop in temperature, which will lead to the death of young mushrooms, and serious big mushrooms will also die. 3. Improper use of water straw mushroom has certain requirements for water temperature, generally requires the temperature of water and room temperature. Such as spraying deep well water at about 20℃ in hot summer, it will cause a large number of young mushrooms to die. Therefore, water spraying should be carried out in the morning and evening, and the water temperature should be around 30 ° C. According to the different stages of growth and development of volvariella volvacea fruiting body, the water spraying method should be mastered correctly. If the fruiting body is too small, spraying too much water will lead to the death of young mushrooms. During the needle stage and the small button stage, the material surface must stop spraying water. If the material surface is dry, it can only be sprayed in the corridor of the cultivation room and poured on the ground to increase the relative humidity of the air. 4. Mushroom picking damage straw mushroom hyphae relatively sparse, easy to damage, if picking too much action, will touch the surrounding culture medium, resulting in hyphae fracture, the surrounding young mushroom hyphae fracture and water, nutrition supply is not up. Therefore, when picking mushrooms, the action should be as light as possible. When picking straw mushrooms, press the growth base of straw mushrooms with one hand to protect other young mushrooms, and twist and pick mature mushrooms with the other hand. If there are dense clusters of mushrooms, they can be picked together to avoid the death of most immature mushrooms due to the collision of individual mushrooms.
