Prevention and control methods for producing small and dense white champignon mushroom
In addition to individual strain characteristics, the main reason is that the relationship between water spraying, ventilation, and mushroom formation is not properly handled under high temperatures. In general, when the temperature is relatively high (19-23 ℃), after covering the soil and spraying water, the ventilation capacity of the mushroom room is low, the relative humidity of the mushroom room is high, and the mycelium growth and development of the material layer and soil layer are vigorous, causing the mycelium growth to be too high. Most of the fruiting bodies are formed on the surface of the soil layer, and the mushrooms are densely formed. The distance from the material layer and soil layer to transport water and nutrients to the surface of the soil layer is far, which cannot meet the requirements of the mushroom body for water and nutrients, Some people call it "balloon mushroom", resulting in small and dense mushrooms. In addition, it is also possible that the cultivation material and soil layer are too thin, which can easily lead to the production of small and dense mushrooms.
Prevention and control methods:
After adjusting the water content of the soil layer, first close the doors and windows to hang the mycelium, so that it can be lifted up above the soil layer, and then hang it to a certain position. After adding fine soil, spray water to strengthen ventilation, so that the mycelium looks like hair thick, transforms into reproductive growth, and twists into mushroom buds in time. When the soil layer has sufficient hyphae and the position is moderate, pay attention to strengthening ventilation and cooling in the morning, evening, and night to promote mushroom formation and control the position of mushroom formation not to be too high.
Pay proper attention to the thickness of the culture material and soil layer. The thickness of the culture material is generally 15-16cm, and the thickness of the soil layer is about 3cm.
If the soil layer is too thin or the mushroom grows on the surface of the soil layer, it is necessary to timely replenish the mud, cover with fine soil, artificially reduce the position where the mushroom grows, meet the water and nutrient requirements of the mushroom body, and improve the condition of dense and small mushrooms.
