How to prevent and treat deformed mushrooms? First, identify the common types
Deformed mushrooms take many forms. The main ones commonly seen in production are: landmine mushrooms, hollow mushrooms, big-bottom mushrooms, hard cap opening and early cap opening, red roots, and water rust spots. Landmine mushrooms. The main cause is that the casing soil material is too coarse, the soil is rather hard, the casing layer is thick, the surface of the casing layer contains relatively little water, while the temperature and humidity conditions of the lower part and the substrate are suitable for fruiting body formation and growth, so fruiting bodies are easily differentiated and formed on the surface of the substrate or in the middle and lower layers of the casing soil, and then push out through the soil surface. Solution: choose high-quality humus soil, preferably peat soil, and mix in a certain amount of rotted cow manure or wheat bran, etc. in proportion; when collecting and sun-drying the soil, it should be sieved so that most soil particles remain comparable in size to @#@245@#@ particles, with the largest about 1/2 the size of a corn kernel, accompanied by some soil particles; casing is generally about 3 cm, and if conditions permit, first apply a layer of coarse soil 1-1.5 cm thick, then fine soil, and pay attention to maintaining uniform moisture content.
