Control Methods for Mushroom Mycelium Failing to Grow into the Substrate
About 10 days after spawning, the mushroom mycelium should visibly grow into the substrate. If this is not the case, it is due to causes such as the compost being too wet or too thick, the interior of the substrate being too dry, or the substrate layer being compacted. The cause should be identified promptly to create favorable conditions for mycelial growth. Although a dry surface is not a problem, never spray water on the bed surface while cultivating the mycelium. If the interior of the substrate is too dry, supplemental nutrient water should be added to the substrate: for every 100 sq m, use 0.9 kg of soybeans, soak them until swollen and grind them into about 90 kg of juice, add 45 yeast tablets, 27 vitamin B1 tablets, and 0.45 kg of white sugar

Why oyster mushroom mycelium fails to fruit for a long time after fully colonizing the substrate, and how to fix it
In oyster mushroom cultivation, you sometimes run into bags or blocks whose mycelium grows very well but, after fully colonizing the substrate, produce no mushrooms for a long time. The main causes and remedies are as follows: 1. The oyster mushroom variety does not match the season. The temperature type of the spawn differs too greatly from the air temperature at cultivation time, which is to say the sowing time was chosen poorly. For example, if a medium-to-low-temperature oyster mushroom spawn is sown at the turn of spring and summer, the mycelium fully colonizes just as the hot season arrives, making fruiting very difficult. Remedy: dig a trench in a shady spot, arrange the bags in it and cover them with soil to oversummer; when the autumn cool arrives and conditions are suitable, dig away the soil cover and carry out fruiting management to reduce losses.
